How to convert PNG to WebP
- Select Choose files, or drag your PNG files onto the box. You can also paste an image.
- Wait a moment. Each file converts on your device, and a progress bar shows the status.
- Select Download for a single file, or Download all (ZIP) when you convert several at once.
No account is needed, and there is no limit on how many files you convert.
Why convert PNG to WebP
WebP keeps transparency and is often 3 to 5 times smaller than PNG. Converting gives you a file that works in the place you need it. Because the conversion runs inside your browser, your files are never uploaded, so private photos and documents stay private. The conversion needs no server at all.
About the formats
PNG is a lossless format that supports transparency. The output format is WebP. Your browser must be able to encode WebP. Chrome, Edge and Firefox can.
Metadata such as camera model and GPS location is dropped during conversion, because the image is redrawn and saved fresh. This is handy when you want to share a picture without revealing where it was taken.
Screenshots, icons and illustrations often see the biggest savings when you switch from PNG to WebP.
Tips
- Convert many files at once. They run in parallel on phones and computers with several cores.
- Use the quality slider, when it is shown, to balance file size and sharpness. Around 90 percent suits most photos.
- Need a different format? Try jpg to webp or webp to png.
- Very large images need a lot of memory. If a file fails on your phone, try a computer or a smaller image.
