Why is the SVG larger than the original image? Path complexity and usage judgment
SVG records path and style. Complex photos or compressed noise may produce a large number of graphics, so the file size is larger than JPG and WebP. The value of vectorization is in the scalability and editing paths, there is no guarantee of compressed files.
Which pictures are easy to generate complex SVG?
Photos, grainy textures, soft shadows, and lots of gradients contain lots of color variation. Tracing these changes may require more paths; the original compressed noise of the JPG may also become additional small patches of color.
When comparing sizes, the number of bytes of the actual downloaded file should be used, and the image details should be confirmed at the same time. Smaller files may lose detail, and larger files are not necessarily more accurate.
When does it make more sense to keep the original bitmap?
If the intended use is photography for web pages, JPG or WebP will often preserve the desired look and feel; pathed SVG is more necessary if you need to adjust the outline of a logo, modify color blocks, or deliver a scalable pattern.
SVG can also embed bitmaps, so the content cannot be inferred from the suffix alone. The actual graphic object should be confirmed in the design software before deciding whether it is suitable for the next step of editing.
How to reduce unnecessary complexity?
Start with an original image with clear edges and a simple background to avoid vectorizing an entire complex photo for web display. Clean up any unwanted background or debris while editing and keep the original file for comparison.
When node simplification or special compression is required, it can be processed in design software with corresponding functions. This site does not call deleting graphics of the same color node simplification, nor does it promise that the file size can be reduced by a fixed percentage.
- First record the file size and intended use.
- Check details at actual display size.
- After cleaning, re-export and check to confirm that no subjects were accidentally deleted.
SVG format basis and reference materials
SVG can contain both vector shapes, images, and text. Therefore, a file name ending in .svg does not alone prove that the original image has been converted to an editable path.W3C SVG 2 Specification: SVG Graphics Objectdescribes these object types.
