ICO to transparent PNG converter.

Drop the ICO, pick the color to clear or leave white selected, raise the tolerance if needed and download a PNG with full transparency.

PNG opens everywhere: Figma, Sketch, web projects, macOS. ICO is Windows' and browsers' format; nothing else cares for it.

The largest frame: an ICO with 16, 32 and 256 gives you the 256. To pick another size, use the plain ICO to PNG converter, which lists them all.

Then you only need ICO to PNG, which keeps the alpha with no color matching. This page is for an icon whose background still has to be cleared.

No. Both formats are lossless; every pixel and color is kept, and PNG carries a full 8-bit alpha, more than old ICO frames had.

Drop the ICO, 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 anti-aliasing 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 a white letter or highlight inside the icon stays. Preview mask shows exactly which pixels will be cleared before you download.

The largest frame of the ICO. A browser's canvas writes PNG, which every editor opens; to get an ICO back, pack the PNG with the PNG to ICO tool at the sizes you need.

No. The ICO is read and its frames decoded by JavaScript on your device; the page makes no request with your file. Load it, go offline and it still works.

No. The ICO to transparent PNG converter 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.
