WebP transparency creator.

Yes. WebP has an alpha channel like PNG, so it holds transparent, semi-transparent and opaque pixels, and a transparent WebP is 25 to 35% smaller than the same PNG.

Drop the WebP, pick the background color to remove, set the tolerance for similar shades and download. The result is a transparent PNG you can convert back to WebP.

For the web, yes: same quality, 25 to 35% smaller. Older software reads PNG more reliably, which is why the tool writes a PNG.

Only still images. An animated WebP decodes to its first frame.

Lossy WebP is smaller and drops some detail, like JPG; lossless keeps every pixel, like PNG. Both carry transparency and both work here. A lossy file may need a little more tolerance to catch compression noise.

No. The browser decodes the file, a canvas does the work and the result is built on your device; the page makes no request with your image. You can load it, go offline and keep working.

The edit is written as a PNG so nothing is lost: it keeps every pixel and the alpha channel exactly. Run the result through the WebP compressor to get a WebP back for the web, usually 25 to 35% smaller than the PNG.

No. The WebP transparency creator is free and opens without a sign-in, an account or an install.

Nothing. The WebP transparency creator holds your input in the page's memory, so closing or reloading the tab clears it, and it saves nothing in this browser.

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.
