What to expect
This is the conversion with the most to gain. A PNG stores every pixel exactly, which is the right choice for a logo and the wrong one for a photograph or a screenshot with a gradient — WebP at high quality typically lands between a fifth and a twentieth of the size with no visible difference. Transparency carries over, which is the part people expect to lose.
How to convert PNG to WebP
-
Drop your files onto the converter, or browse for them.
-
The output format is already set for this conversion — adjust the quality or size if you want to.
-
Download each file, or the whole batch as a single ZIP.
Worth knowing
- Nothing is uploaded. The work happens in your browser, so the files never reach a server — go offline and try it.
- Conversion strips embedded metadata, including the GPS coordinates a phone writes into every photo.
- Convert a whole folder at once and download it as one ZIP, with no per-file queue or daily cap.
Nothing leaves your device
There is no server to upload to. The page is a folder of static files; the conversion happens in the tab using your own processor. Convert something with your Wi-Fi switched off and you can see this for yourself.
