WebP Converter
Convert to and from WebP.
WebP Converter turns JPG and PNG files into WebP for smaller pages, or turns WebP files back into JPG and PNG when something in your workflow will not accept them. Both directions run on a canvas in your browser, in batches, with a quality control and no upload.

Questions about WebP Converter
How much smaller is WebP?
Typically 25-35% smaller than JPEG at visually equivalent quality, and often 20-30% smaller than PNG for graphics with flat colour. Gains are largest on photographic content.
Does WebP support transparency?
Yes, including lossy transparency, which PNG cannot do. That makes it a good replacement for large transparent PNGs.
Is WebP supported everywhere?
Every current browser supports it. The remaining friction is desktop software and older systems — which is exactly why the reverse direction exists here.
Why will my computer not open a WebP I downloaded?
Plenty of desktop software still has no WebP decoder even though every browser does — older Photoshop versions, some Office builds, a few photo viewers. Converting the file back to PNG here fixes it, and PNG output keeps the pixels exactly as decoded.
Does an animated WebP keep its animation?
No. Conversion draws a single frame to a canvas, so an animated WebP comes out as a still picture of its first frame. There is no animated output format in this tool, and it says so rather than quietly dropping the other frames.
Is WebP Converter really free, with no limits?
Yes. There is no account, no daily cap, no file-size tier and no watermark, because there is no server cost to recover. The site is funded by clearly disclosed partner recommendations on the Partners page, never by metering the tools.
Are my files or text uploaded when I use WebP Converter?
No. Everything is processed by JavaScript running in your browser, on your device. You can verify it: open your browser's developer tools, switch to the Network tab, and use the tool. You will see no request carrying your data — because there is nowhere for it to go.
