Convert PNG to WebP

No. The tool runs entirely in your web browser. Your images are read from your device, processed in memory and saved straight back to it. They are never uploaded, stored or seen by anyone.

Yes. WebP has an alpha channel, so transparent and semi-transparent areas, such as soft shadows and smooth edges, are kept. That makes it a good replacement for PNG logos, icons and cut-out product photos on a website.

It depends on the image. Photos and detailed artwork saved as PNG often shrink by three quarters or more. Simple graphics with a few flat colours are already compact as PNG, so they shrink less. Each file’s size before and after is shown.

At the default quality of 85 they usually look clean on screen. For screenshots full of small text, raise the quality to 90–95. If every pixel must stay exactly as it is, keep the PNG and optimise it losslessly with the image compressor instead.

Yes. Add as many images as you like, up to 50 MB each and 500 MB in total. A file over the limit is skipped and the others are still added. Each one gets its own result and download link, and “Download all” saves them together as a ZIP file.

Yes. There is no sign-up, no watermark and no daily limit. Because all the work happens on your own device, there are no servers to pay for.
