Image Converter — HEIC, PNG, JPG, WebP
Convert between HEIC, PNG, JPG, WebP and ICO — including HEIC-to-JPG for iPhone photos that other apps can't open — and optionally cap the output at an exact KB in the same step.
What it does
- Auto-detects the input format; you just pick the output.
- Batch conversion for multiple files at once.
- Combine format conversion with an exact-KB target in one pass.
Private by design
Processing runs entirely inside your browser tab — your photo or document is never uploaded to a server.
Good to know
Because nothing is uploaded, there's no wait for a server queue — the result appears as soon as your own device finishes the work, which is usually just a second or two on a normal photo.
How it works
Frequently asked questions
Does converting HEIC to JPG lose quality?
There's a small, generally invisible quality trade-off — HEIC's extra efficiency partly comes from a slightly different compression approach than JPEG.
Can I convert straight to a specific KB size?
Yes, set both the output format and a KB target together.
