FAQ

Will my WeChat avatar actually be transparent?

WeChat shows transparent areas as white, so it looks like a clean white-background avatar — not truly invisible. For a colored avatar, add a background color before uploading.

How do I add a solid or gradient color?

After cutting to a transparent PNG, add a color or gradient in any image tool (even your phone's editor) and export.

Does it handle pets and hair?

Free local BiRefNet Lite handles fur and hair edges best on clean backgrounds; Pro adds a Fine cloud model option.
