Convert PNG to WebP

Drop your PNG files below. Conversion happens on your device — nothing is uploaded, and there is no limit on how many you convert.

Quick answer. Converting PNG to WebP re-encodes the image in a different container and codec. Lossless WebP is 26% smaller than PNG on average and often far more on screenshots, with pixel-identical output. It is the single easiest byte saving available on most websites. An 800 KB screenshot PNG typically becomes 110–190 KB as lossless WebP. This tool does it with your browser's own codecs, so the file never leaves your device.

Lossless WebP is 26% smaller than PNG on average and often far more on screenshots, with pixel-identical output. It is the single easiest byte saving available on most websites.

What is lost in the conversion?

Nothing, in lossless mode. Transparency and color depth carry across exactly.

How much smaller will the file be?

File size depends heavily on image content. Photographs, screenshots and line art compress very differently, so treat these figures as typical rather than guaranteed.

Frequently asked questions

Is PNG to WebP conversion lossy?

No. WebP is lossless, so every pixel of the decoded source is preserved exactly.

Will I lose transparency?

No. WebP supports an alpha channel, so transparency is preserved.

Can I convert several files at once?

Yes. Drop as many as you like and download the whole batch as a ZIP.

Is there a file size limit?

No server-imposed limit. The ceiling is your device's memory, which is far above what upload-based converters allow.

Does it add a watermark?

No. No watermark, no daily cap and no signup.

Are my images uploaded?

No. Decoding and encoding both use your browser's built-in codecs on your own device.
