Transparent AVIF maker.

Drop any image (AVIF, PNG, JPG, WebP), pick the background color to remove, tune the tolerance and download the transparent PNG. Encode that PNG as AVIF with Squoosh, Sharp or your build; browsers don't write AVIF from a canvas outside Chrome.

Size. A transparent AVIF is typically 50 to 70 percent smaller than the PNG and 30 to 50 percent smaller than the WebP. On a shop or a portfolio with many cut-outs, that is a visibly faster page.

Clear the background here, download the PNG, encode it as AVIF with alpha, and serve it in a picture element with a WebP and a PNG fallback.

Open it in a browser: transparent areas show the page behind. Or drop it here; the preview draws it on a checkerboard. Some viewers paint white where the file is transparent.

On the web, increasingly; in email, documents and older software, PNG stays. Make both and let the picture element choose.

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 Transparent AVIF maker 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.

No, it takes one file at a time. If you drop or choose several, only the first is used; run the tool again for the next one.

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.
