Should I convert HEIC to PNG or JPG?

Choose PNG when you want lossless quality and crisp edges — screenshots, images with text, graphics, or anything you will edit again. Choose JPG when you want the smallest file for photos to email or post. For typical iPhone snapshots that are mostly for sharing, JPG is smaller; for archival or editing, PNG keeps every pixel intact.

Will I lose any quality converting HEIC to PNG?

No. PNG is a lossless format, so the decoded image is stored exactly with no new compression artifacts. The only caveat is that HEIC itself is already a compressed photo, so PNG preserves whatever detail the HEIC contained — it cannot add back detail HEIC discarded.

Why is the PNG so much larger than the HEIC?

HEIC uses modern, highly efficient compression, while PNG stores image data losslessly. A 2MB HEIC photo can easily become a 10–20MB PNG. That is the normal trade-off for lossless quality. If size matters more than perfect fidelity, convert to JPG instead.

Does PNG keep transparency from my image?

Yes. PNG supports an alpha channel, so any transparency is preserved. Standard iPhone photos do not contain transparency, but if your HEIC came from an edited or cut-out image, the transparent areas stay transparent.

Are my iPhone photos uploaded to a server?

No. Every byte stays on your device. Conversion runs locally in your browser via WebAssembly — no upload, no server storage, nothing logged. You can confirm this in DevTools → Network: no file transfer happens during conversion.

Can I batch convert many HEIC files to PNG?

Yes — drop up to 20 files at once. They convert in parallel and you can download them individually or as a single ZIP.

Does it work on Android and Windows?

Yes. Open the page in Chrome, Edge, or Firefox on Windows, or Chrome on Android. No HEIF extension purchase from the Microsoft Store is required.

What is the maximum HEIC file size?

Up to 100MB per file, which is far larger than the 1–4MB files modern iPhones produce.
