Image Format Converter
Convert an image between PNG, JPEG and WebP formats.
What is the Image Format Converter?
This tool converts an image from one format to another — PNG, JPEG or WebP — entirely in your browser. PNG preserves transparency and sharp edges (good for logos and screenshots), JPEG is a compact, universal format for photos, and WebP generally offers the best compression of the three for similar visual quality.
How to use it
- Choose an image from your device.
- Pick the format you want to convert it to; a quality slider appears for JPEG and WebP, since those are lossy formats.
- Click Convert Image and then Download the result.
A common reason to convert formats is compatibility: some upload forms only accept JPEG or PNG, or you might want to switch a PNG screenshot to JPEG to shrink its file size when transparency isn't needed. Converting to PNG from a JPEG won't recover detail that JPEG compression already discarded, since PNG can only preserve what's already there. As with the other image tools on this site, the conversion runs on your own device using the Canvas API, so your image is never sent to a server.
