How to use
- Drag your PNG files into the box above or tap Choose files. You can add many at once.
- Adjust Quality if you like. The default (90) already looks virtually identical to the original.
- When it finishes, tap Save on each file or Save all (ZIP) to download everything at once.
Good to know
PNG is a lossless format, so no quality is lost when saving. It supports transparency, which makes it popular for logos, icons, screenshots and design work, but photos saved as PNG are large.
WebP is an image format created by Google for the web. It is smaller than JPG and PNG at similar quality and supports transparency, so many websites use it — but some editors and older software still cannot open it.
Converting PNG to WebP keeps the transparent background while cutting the file size dramatically. Higher quality values stay closer to the original; around 80 usually looks the same to the eye at a fraction of the size.
Everything happens inside this browser. Your files are never sent over the internet, so personal photos and work images stay private, and the converted files no longer carry metadata such as GPS location.
FAQ
Is the transparent background kept?
Yes. WebP supports transparency, so the PNG’s transparent areas stay transparent.
Are my files uploaded to a server?
No. Conversion runs entirely in your browser on your own device. Your files never leave your computer or phone.
Can I convert many files at once?
Yes. Add as many files as you like; they are converted one after another and you can download them all with Save all (ZIP).
Does it work on my phone?
Yes, in iPhone and Android browsers. Very large images may be scaled down automatically to fit your device’s memory.
