What it does
Convert Image Format works on JPG, PNG, WEBP and HEIC images and writes a new file; the one you dropped in is untouched. JPG, PNG and WebP, converted freely.
When you need it
Usually because something downstream has an opinion: a profile photo that must be square, a marketplace that rejects anything over a certain width, a print that needs the right proportions, or a phone photo that arrived rotated.
Limits and caveats
Enlarging an image cannot add detail that was never captured, so scaling up softens it. Saving to a lossy format re-encodes the pixels, which is worth doing once rather than repeatedly on the same file. Everything happens in your browser, so the file never leaves your device.

Frequently asked questions
- Does PNG to JPG keep transparency?
- JPG has no alpha channel, so transparent areas become white.

- No. This tool runs entirely in your browser, so the file never leaves your device.
