Not every image format works everywhere β a website might reject a PNG that's too large, or you might need a lossless format for editing instead of a compressed JPEG. Our free Image Format Converter converts between PNG, JPEG, and WEBP directly in your browser using the Canvas API.
If your image has transparent areas and you convert it to JPEG, the transparency will be filled in with white, since JPEG doesn't support it β use PNG or WEBP instead if you need to keep it. Start with a quality setting around 80β85% for JPEG or WEBP; it's usually indistinguishable from full quality while noticeably shrinking the file size.
Conversion happens entirely on your device through the Canvas API β nothing is uploaded to a server. Try it now with the free Image Format Converter, or shrink a large photo further with our Image Compressor.
