Go to User Guide →01 Start with the original image format
Handle format differences such as material preparation, transparency channels, and compressed edges.
WebP to SVG
Static WebP can be uploaded directly for SVG vectorization without converting to JPG first. It is suitable to give priority to logos, icons and flat illustrations with clear edges; transparent backgrounds need to be checked after conversion, and animated WebP will not automatically turn into SVG animation.
Read the format guide →PNG to SVG
PNG is commonly used for transparent background icons, logos and graphic illustrations. The key to converting PNG to SVG is to trace the color blocks and edges in the pixels into paths for easy scaling and editing. Here we introduce how to check transparent areas, what original image is more suitable, and the cleaning steps after conversion.
Read the format guide →JPG to SVG
JPG / JPEG is suitable for storing photos and is often the only logo format on hand. Determining the compression traces and image complexity before conversion can help you choose the appropriate original image and reasonably evaluate the editing value of SVG.

Using vector conversion for the first time: from uploading to saving files
Prepare a PNG, JPG or WebP with clear edges, log in and confirm that your membership is valid, then upload and check the original image and results, and finally save the file to your device. It is recommended to choose a simple icon for first time use.
Read full text →The upload prompt format is not supported: How to check the true format of the image
This site accepts PNG, JPEG and WebP images. Directly changing the suffix of a HEIC, GIF, PDF or SVG file will not turn it into a supported image. You should actually export a static PNG or JPEG in a software that can open it.
Read full text →What should I do if the image exceeds 10 MB? Crop first and then compress appropriately
When the upload limit is exceeded, first cut off the irrelevant white space and background, and then use image software to adjust the size or compress according to the purpose. Prioritize preserving text, edges, and cutouts to avoid repeatedly saving lossy JPEGs in order to reduce file size.
Read full text →Picture cannot be read: troubleshooting order for damaged files and fake pictures
If it cannot be read, open the original image locally first, and then check whether a web page, empty file or incomplete image has been downloaded. If the original image is normal, try re-exporting it to a standard static PNG in the image software before uploading it.
Read full text →What should I do if tasks keep being queued? Understanding Queues and Waiting States
Queuing means that the task has been accepted but has not yet started execution. Check the status of existing tasks first, and do not upload again. The server queue will still be retained after closing the page, and you can continue querying by reentering the studio.
Read full text →What should I do if the conversion takes a long time? Select next step by task status
First distinguish between queuing, allocation and execution. Images with complex textures and many paths may be slower. The temporary lack of results on the page does not mean failure; you should continue querying or use the Cancel button to wait for confirmation.
Read full text →How to cancel the conversion task? The difference between queuing and execution
Select the task in the studio and click the Cancel Queue or Cancel Task button in the wireframe. Cancellation requires server confirmation; when the button displays Confirming, continue to wait for the status to refresh before deciding whether to submit a new image.
Read full text →Why can’t I upload multiple photos at the same time? How to lift single task restrictions
The same account only allows one conversion task in progress at a time. The official website and the extension share this restriction. The next conversion can only be initiated after the existing task succeeds, fails, or is confirmed to be cancelled.

03Vector Basics
Understand paths, coordinates, padding, transparency and file formats, and avoid using file suffixes as quality judgments.
The difference between bitmaps and vector graphics: judging usage from pixels and paths
Bitmaps record pixel colors, and vector graphics describe outlines with geometric shapes. Photos are usually suitable for bitmaps, and flat logos and patterns that need to be scaled are often suitable for vectors; the two types solve different needs and are not substitutes for each other.
Read full text →How to judge whether SVG is a real path or an embedded image
Select the object in an editing software that supports SVG and check whether the path nodes can be edited. SVGs containing image elements may still rely on bitmaps; simply changing the suffix or wrapping the PNG in SVG does not equal vectorization.
Read full text →What is the viewBox of SVG? Coordinate range and canvas size
viewBox defines the coordinate range used internally by SVG, usually consisting of a starting point, width and height. It is not the same indicator as document pixels and printing resolution. A larger value does not mean a clearer image.
Read full text →SVG width, height and display size: why it looks large after importing
SVG can contain both internal coordinate ranges and external display width and height. The import software interprets units and artboards differently, which may make the same file look different in size; check the size and proportion first, and then determine whether the path is wrong.
Read full text →What is the difference between SVG fill and stroke? View object before deleting
The fill determines how the inside of the shape is colored, and the stroke is drawn along the outline. The same visual effect may consist of a filled path or a stroked line, and removing a stroke only affects the actual stroke, not all shapes that look like lines.
Read full text →Is the more SVG path nodes the better? Complexity and editing costs
Having more nodes does not mean it is more accurate. Over-density of nodes may come from noise, texture or tracing errors, which will increase the editing burden; over-simplification may change sharp corners, small characters and curves, so judgment should be based on the target outline.
Read full text →SVG Why does the hollow become solid? Compound paths and fill rules
Hollows such as letter holes and ring patterns depend on path structure and filling rules. When making it solid after importing, first check the compound path and fill-rule. Do not simply cover the inner hole with a white block instead of being truly transparent.
Read full text →SVG transparency and transparent background: two concepts that are easily confused
Transparent background means there is no opaque basemap outside the subject; object transparency controls whether the subject itself is translucent. The pattern can reveal the background color, which may be due to the translucence of the object or missing graphics, which need to be judged separately.
Read full text →04Material preparation
Check the original image, edges and details first to reduce blur, noise and missing parts found after conversion.
How to choose the original image suitable for converting to vector: five check points
Priority is given to pictures with complete subjects, clear edges, clear color blocks, and without repeated compression. The more complex the background and the denser the small text, the more subsequent cleaning and checking is usually required; large size is no substitute for true detail.
Read full text →Can screenshots be converted into vectors? Impact of browser scaling and compression
Screenshots can be input as bitmaps, but the screen is limited by the display size, screen scaling and screenshot range. When the original image can be downloaded, the original image will be downloaded first to avoid cutting the thumbnail in the browser into low-detail material.
Read full text →JPG How compression noise affects vectorization: first look around the outline
JPEG compression can leave blocking, noise, or ringing near high-contrast edges, and tracing can turn these traces into extra paths. Prioritizes finding uncompressed originals rather than multiple transfer formats.
Read full text →Transparent PNG has white edges: how to check before converting to vector
Place the transparent PNG on a dark background and check. If a light halo appears on the edge, it may contain white semi-transparent pixels. Vectorization traces the visible edges, possibly preserving or enhancing the ring of noise.
Read full text →Do I need to crop before converting to vector? The choice between white space and main body proportion
Irrelevant white space and complex background can be cut off first, so that the processing can be concentrated on the subject. When cutting, keep the complete outline, shadows and necessary decorations, and do not cut the graphics close to the edge of the canvas.
Read full text →Convert black and white line drawing to SVG: How to retain thin lines and closed areas
For black and white line drawings, the gray background of the paper and scanning noise need to be cleaned first, while retaining the finest strokes. The black outline may form a closed color block after tracing, and may not necessarily be a single-line center path that can be directly used for tooling.
Read full text →Convert hand-drawn scanned manuscript to vector: How to deal with paper texture, tilt and brush strokes
First correct the scan tilt, cut off the edges of the paper, and then distinguish the brush strokes that need to be retained and the paper grain that should be cleaned. Brush stroke particles are also graphic information, and paths will be added after tracing. You cannot expect complete preservation and minimalist nodes at the same time.
Read full text →Are photos suitable for converting to vector? First, decide whether you need contour or texture.
Photos can be traced into path color blocks, but may change lighting, skin, and texture. Bitmaps are usually retained when a realistic photographic look is required, and pathing is considered only when a silhouette or flat poster effect is required.

06Editing and troubleshooting
Focus on specific problems, first determine the cause, and then choose editing or material processing methods.
There are still jagged edges after converting to SVG: first distinguish between path and display issues
The aliasing may come from the polylines traced in the original image, or it may just be a small rendering of the screen. First enlarge the path and change the display environment to compare, confirm whether the outline really has redundant vertices, and then select the trimming method.
Read full text →SVG color is different from the original image: check from transparency and display environment
First compare in the same background color, the same size and the same software. Transparent edges, tracing and merging color blocks, color configuration and monitor settings may affect the look and feel. You cannot determine the color value error based only on screenshots of different windows.
Read full text →There are many small fragments in SVG: how to distinguish noise from details
First determine whether the fragments are valid textures in the original image or are residues from compression, scanning or cutout. Determine the retention range according to the target display size, and make a backup before cleaning to avoid deleting eyes, stamens or small font punctuation together.
Read full text →Thin lines disappear after converting to SVG: How to determine whether it can be repaired
First check whether the thin lines in the original image are already very shallow, very thin, or have been scaled and compressed. If information is missing during the input stage, automatic conversion cannot reliably complete it; priority should be given to using clearer materials or manually redrawing necessary lines.
Read full text →There are white gaps between adjacent color blocks: real gaps or rendered thin lines
First change the zoom ratio and background to see if the white seam changes with the display. Adjacent paths may appear thin lines during screen anti-aliasing, or there may be real gaps. The path boundaries should be checked before processing instead of bolding all graphics directly.
Read full text →SVG is blank after importing: first check the artboard, color and external links
Blank spaces do not necessarily indicate a corrupt file. First check whether the object is outside the drawing board, whether the white graphics fall on the white background, and whether external resources are missing, and then determine whether the target software supports the file content.
Read full text →SVG edges are cropped after import: canvas and stroke range check
Check the viewBox, artboard bounds, clipping paths, and strokes beyond bounds. Just because the outline itself is within the canvas, it does not mean that all line widths drawn along the outside of the outline are also within the canvas.
Read full text →The pattern disappears after removing the stroke: How to determine whether the stroke is necessary
Lines displayed by stroke alone will not be visible when the stroke is removed. Undo first and check the fill and stroke structure of the pattern; when you need to retain the outline, you cannot clear all strokes with one click.

From responsive display, theme color matching to delivery dependencies, check the effect of using SVG in real web pages.
How to adapt the width of web page SVG? Proportions and Container Checks
Keep the correct viewBox and let the display width change with the container and the height adjust proportionally. The responsive layout changes the display size, and the internal path coordinates do not need to be regenerated for the mobile phone screen.
Read full text →Should I use img or inline SVG for web pages? The trade-off between style and isolation
Using img to reference SVG is suitable for ordinary independent pictures, and inline SVG facilitates page style control of internal graphics. The selection method depends on whether path-by-path interaction, color change, and maintenance are required. You cannot just compare the length of the writing method.
Read full text →How to follow the text color of web page in SVG? Usage boundaries of currentColor
The fill or stroke of an inline SVG can inherit the current text color using currentColor. If the color values are hardcoded internally in the file, or loaded independently using an img, changing the color of the outer text will usually not change the graphic as expected.
Read full text →How to write SVG alternative text? Distinguish between content images and decorations
Informative SVG should provide alternative text that expresses the purpose, and is purely decorative to avoid repetition. The text description focuses on the information conveyed by the image, rather than mechanically writing a string of colors and path shapes.
Read full text →The colors are messed up after multiple SVGs are placed on the same page: check for duplicate IDs
When inlining multiple SVGs, gradient, mask, or crop references may have duplicate IDs, causing the graphic to point to a different definition. First look at the url(#...) reference and the corresponding ID, and use a consistent and independent prefix for each instance.
Read full text →The web logo looks too small: first check the SVG’s built-in white space
If the image element fills up the container but the logo still appears small, it may be that the SVG canvas contains a lot of white space. Check the body bounds and viewBox before deciding to crop the canvas or resize the page.
Read full text →What should I do if the social platform does not accept SVG? Keep the master and then export
First check the upload format requirements of the target platform. If you do not accept SVG, export the PNG or JPEG supported by the platform from the vector master, check it according to the actual size, and do not simply change the suffix and upload it.
Read full text →What details should be simplified before using the logo as a website favicon?
The display area of the favicon is very small, so you should use a main mark that can be recognized in a small size, and remove unnecessary small characters and complex decorations. A full horizontal logo usually cannot be directly reduced to obtain a clear icon.

Establish a complete design workflow from e-commerce art, AI materials and cutouts to pattern repetition, size and printing delivery.
Image to DXF: PNG, JPG outline conversion and CAD size check
Upload PNG, JPG or WebP in the image to vector studio, and the DXF outline can be downloaded after the new task is completed on the member side. This file is the result of a raw conversion and does not contain subsequent modifications by the SVG editor. It is not a centerline tracing, automatic annotation, or a ready-to-process CAD drawing.
Read full text →Cut out the image first or convert it to SVG? Sort by subject and background selection
When the background is complex and only the subject is needed, you usually cut out the image first and check the transparent edges, and then determine whether the subject is suitable for vectorization. There are already transparent logos that can be converted directly; when you only need a transparent photo, exporting a PNG may be sufficient.
Read full text →How to convert AI-generated patterns to SVG? From sketches to editable footage
First confirm whether the AI tool exports a bitmap or an actual vector path. Bitmap patterns need to be checked for text, outlines and color blocks before tracing; if there are already editable vector files, they can be sorted directly in the design software without having to convert them into images and then trace them again.
Read full text →How to check the design documents before sending the printing pattern to the factory?
First confirm the process, actual size, color requirements and receiving format with the factory, and then check the text, background, thin lines and white space in the pattern. SVG is just one of the file formats, and the completion of vectorization does not mean that it is suitable for all printing processes.
Read full text →Introduction to pattern design: What are repeating units and seamless patterns?
Repeating units are basic blocks arranged continuously according to certain rules; seamless patterns require adjacent blocks to be naturally connected at the edges. Converting a single image to SVG does not automatically establish repeating rules, nor does it guarantee no seams when tiled.
Read full text →Pixels, PPI and print size: How big can the image be printed?
When a bitmap is not resampled, the printed width in inches is equal to the number of horizontal pixels divided by the PPI; centimeters are multiplied by 2.54. The required PPI is determined by the purpose and producer. Modifying the resolution tag alone will not increase the details of the original image.
Read full text →How to organize e-commerce art materials? From main image, logo to delivery documents
First organize the materials according to purpose: keep high-quality bitmaps for product photos, keep vector source files as priority for logos and icons, and keep editable drafts for typesetting. Export sizes separately from different channels, and save source files, preview drafts and final delivery drafts separately.
Read full text →How to check color blocks and color separations before using SVG for screen printing
First confirm the design color, substrate and format received by the producer, and then check the relationship between each color block, hollowing out and overprinting. The existence of a path in SVG does not mean that the screen color separation has been completed. The actual color version and process parameters should be confirmed by the producer.
