Remove the white background from an AVIF.

Drop the AVIF; white is selected as the color to remove. Set tolerance to 10 to 20 percent for off-white and cream, turn on outer pixels only if the subject has white in it, and download.

Turn on outer pixels only. Then only white connected to the edges goes, and white text, highlights and eyes inside the subject stay.

0 to 5 percent for pure #ffffff; 15 to 25 for slightly grey or cream; 20 to 30 for a photographed white sheet. The mask preview shows what goes before you commit.

Some exporters flatten the alpha to white, or the file was saved without it. Clear the white here and you get the transparency back, in a PNG you can re-encode.

With a picture element: an AVIF source, a WebP source, then an img with the PNG. Each browser takes the best it supports.

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.
