PNG to WebP
Convert PNG to WebP free, on your device. Drop up to 50 files, convert, download. Nothing is uploaded and there is no watermark.
Runs on your device. Nothing is sent to a server. Files are checked by content, not by name.
How it works
Drop your PNG files or tap to choose them, press Convert, then download each file or all at once. The quality slider controls file size; 90% is visually identical to the original for photos.
PNG is lossless and supports transparency, which makes files large. WebP is what most websites serve today because it is small. Many editors, print shops and older programs still do not open it. Converting in the browser means the originals never leave your phone or computer, which matters for personal photos and documents.
Questions
Is there a file limit?
50 files per batch and 50 MB per file. Large phone photos convert in about a second each.
Why does my file say it is not a PNG file?
We check the real content of the file, not its name. A photo renamed to .png is still what it was and should be converted with the matching tool.
