How to remove white background from SVG? First distinguish between background color and graphics

If you see a white background, do you need to delete it?

Not necessarily. A browser or editor may display a transparent SVG with a white canvas. Switch between black, white and transparent previews, observe whether the background changes with the preview, and then determine whether there are actual white graphics.

Switching the canvas background color only affects the viewing mode and does not modify the SVG. Don't rely on the white area on the screenshot as the only basis for an existing background path.

How to delete the background by color in the editor of this site?

Open the editing SVG in the task results, select the suspected background fill color, and first observe the highlight range. Only delete the highlighted areas when they match expectations; this is not a smart cutout that automatically recognizes the subject.

1. Save the original SVG as a basis for restoration.
2. Select white or another background fill color and check all highlighted areas.
3. Carry out deletion after confirming that the same color part of the main body will not be accidentally deleted.
4. If details are lost, undo it immediately; if it cannot be separated, keep the original and process it further in software that supports object editing.

How to confirm the transparency effect after deletion?

Check edges on both black and white backgrounds to avoid light-colored fragments being ignored on white. The inner holes of the text, the whites of the eyes, and the decorative blanks are often the same color as the background, so they should be confirmed one by one.

After completion, export the SVG through the editor and reopen the exported file for verification. The original result downloaded from the task page will not include this deletion operation, and the edited content will not be automatically saved.
