About this tool
WebP to PNG writes a still PNG on this device. Animation is not preserved. The file may grow. Use it when a program cannot open WebP, not as a way to compress a photo.
WebP to PNG stays on this device. The download is the copy you keep, and Weesize does not store a second one. Close the tab when you are finished and the bytes are gone.
- No upload: the WebP to PNG encode uses this browser, not a conversion API.
- Speed: the file does not travel to a server and back, so the wait is only the work itself.
- Quality: the original is kept when the new file would be worse or is not actually smaller.

When is “WebP to PNG” the wrong job?
