FAQ

Common questions about PNG to WebP.

How do I convert PNG to WebP?
Drop your PNG file (or a whole folder) onto the converter. The browser decodes the PNG and re-encodes it as WebP, then gives the file back to download. No upload, no signup, no install. For multiple files, they bundle into a single ZIP.
Is the PNG to WebP converter really free?
Yes. No accounts, no daily caps, no per-file size limit, no watermark. The whole conversion runs in your browser, so there is nothing to ration.
Do my PNG files upload anywhere?
No. The PNG decoding and WebP encoding both happen on your device. Nothing uploads, nothing is logged. Close the tab and the files are gone.
What's the difference between PNG and WebP?
PNG is lossless and supports transparency, which makes it ideal for logos, screenshots, and graphics. PNG photos are usually 5 to 10 times larger than JPEG. WebP is Google's modern format, about 25 to 35% smaller than JPEG at the same quality, with transparency support. Every modern browser reads it, but some older email clients and desktop apps still don't. Converting PNG to WebP makes sense when you need WebP's compatibility or features for your target platform.
Can I batch convert many PNG files at once?
Yes. Drop a whole folder or multi-select files. Each one converts in turn and the WebP files bundle into a single ZIP for one-click download.
