How it works
JPG is best for photos and is supported everywhere. PNG is lossless and keeps transparency, ideal for screenshots, logos and graphics with text. WebP gives smaller files than JPG at similar quality and supports transparency; all current browsers support it.
JPG cannot store transparency, so transparent areas are filled with the background colour you choose (white by default). The tool reads any format your browser can display, which includes GIF (first frame), BMP and, in most browsers, AVIF.
Frequently asked questions
How do I convert PNG to JPG without a black background?
Transparent pixels need a fill colour in JPG. Pick white (default) or any colour under "Background for transparent areas".
Can I convert HEIC photos from an iPhone?
Only if your browser can open HEIC (Safari on Apple devices can). Otherwise set your iPhone to "Most Compatible" in Camera → Formats, or share the photo as JPG.
Is WebP supported everywhere?
All current major browsers support WebP. Some older desktop software does not, so use JPG or PNG for maximum compatibility.
Are files uploaded?
No, conversion runs in your browser.
Limitations
- Animated GIF and animated WebP become a single frame.
- AVIF output is not offered because browsers cannot encode it from a canvas yet.
- HEIC input works only in browsers that can decode it.
