Make a WebP transparent.

Drop the WebP, pick the background color, set the tolerance for similar shades and download. Everything runs in your browser and the output is a transparent PNG.

Yes. Only pixels of the color you pick, within the tolerance, become transparent; the rest of the image is untouched.

Yes: no watermark, no signup, no limits. It runs on your device, so the images stay private.

A WebP with transparency is 25 to 35% smaller than the same PNG, and every current browser reads it, so it's the better choice for a website.

Images with a solid-color background. Turn on Outer pixels only to keep that color inside the subject and Smooth edges for anti-aliased boundaries.

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.

Nothing. The "Make a WebP transparent" tool 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.
