Image Converter
Convert an image from one format to another — PNG to JPG to save space, anything to WebP for the web, or JPG to PNG when you need a lossless copy.

How to use the Image Converter
Add your images
Drop one or more images onto the upload area.
Choose the output format
PNG is lossless and supports transparency. JPEG is smallest for photographs. WebP is a good modern default for the web. AVIF is smaller still, where your browser can write it.
Set the quality
For JPEG, WebP and AVIF, the quality slider trades file size against fidelity. PNG is lossless, so the slider does not apply.
Convert and download
Press Convert and download the results.
Where your files are processed
Your files are processed locally in your browser and are not uploaded to our servers.
The Image Converter runs as JavaScript on the page you are reading. When you choose a file, the browser hands it to that code directly — it is never put into a network request, so there is no upload to cancel, no copy sitting in a queue somewhere, and nothing for us to delete afterwards. We could not see your file if we wanted to.
You can verify this rather than take our word for it: open your browser’s developer tools, switch to the Network tab, and run the tool. You will see no request carrying your file. Better still, once the page has loaded you can disconnect from the internet entirely and the Image Converter will keep working — which it could not do if it depended on a server.
To be exact about what doesleave the page: like the rest of this site, it loads analytics, which record that a tool was opened and whether it succeeded. Those events carry the tool’s name and a duration — never a file, a file name, or anything read out of your file. The tool panel above is also excluded from session recording, so nothing shown inside it is captured either.
