Remove a color from an AVIF.

Drop the AVIF, click the color in the preview or type its hex, widen the tolerance to catch its shades and download. The matched pixels become transparent in the PNG.

Yes. Select the green, raise the tolerance until the backdrop is fully in the mask, and leave outer pixels only on so green inside the subject isn't lost. Photographed backdrops want 15 to 25 percent.

A lossy AVIF shifts colors a little near edges, so an exact match leaves a fringe. 15 to 20 percent tolerance and edge smoothing take care of it.

One per pass. Download, drop the PNG back in and pick the next color; PNG loses nothing between passes.

Drop the AVIF, then pick the color to remove: click it in the preview or type its hex. Tolerance widens the match to nearby shades; 0 takes the exact color only and 10 to 20 catches compression noise and off-whites. The result is a PNG with real alpha.

Turn on outer pixels only. Then only matching pixels connected to the edges go, so white text or highlights inside the subject stay. Preview mask shows exactly which pixels will be cleared before you download.

Browsers write PNG and WebP from a canvas but only Chrome and Edge write AVIF, and a PNG is what every editor and site accepts. Keep the PNG as your source and encode AVIF, with its alpha, in your build or an encoder such as Squoosh.

No. The file is decoded by your browser and every pixel is handled by JavaScript on your device. The page makes no request with your image, and you can load it, go offline and keep working.

No. The "Remove a color from an AVIF" tool is free and opens without a sign-in, an account or an install.

Up to 100 MB per file, the limit the tool states under its drop area. A larger file is refused with a plain message instead of being decoded.

The edit is written as a PNG because PNG stores every pixel exactly, with a full alpha channel, so the result can be edited again without a second round of loss.

No. The browser decodes the image and the tool writes a new file from its pixels, so camera EXIF, GPS position and text chunks in the original are not copied into the result. Keep the original file if you need them.

No. The result has the same width and height in pixels as the source.
