This converter needs JavaScript. It runs entirely in your browser and nothing is uploaded.
Looking for video or audio? Those live on the video pages. Word, Excel and other documents need a server-side engine, so I don't offer them — CloudConvert handles those.
Files are read and written on your device. The page never uploads them, so there is nothing to delete later.
Convert as many files as you like, as often as you like. There is no queue and no daily cap.
Your browser does the work, so a batch finishes in seconds and keeps working without a connection.
Drop PNG files onto the box, or click to browse.
Pick a quality. Start at 85% and compare the sizes the tool reports.
Convert, then download individually or as a zip.
If you run a website, WebP is the format Google has been nudging everyone toward for years. It keeps transparency like PNG, compresses like JPG or better, and every current browser displays it. A 1 MB PNG illustration often lands under 150 KB as WebP with no visible change.
This converter uses the WebP encoder built into your browser. Move the quality slider to trade size against fidelity; for graphics with flat colour 85% is usually indistinguishable from the original.
Everything runs locally. Your images never leave your device.
Yes. WebP supports alpha transparency, which is exactly why it is the usual replacement for PNG on the web.
Chrome, Edge, Firefox, and Safari 16 or newer all encode WebP. On an older Safari the tool will tell you it cannot create WebP rather than silently handing you a PNG.
Yes. Every browser released since 2020 displays WebP, and it has been in Safari since version 14. For very old browsers you can serve a PNG fallback with the picture element.
