When should I pick PNG instead of JPG for HEIF?

Pick PNG for lossless quality: screenshots, images with text, graphics, logos, or anything you will edit again. Pick JPG when you want the smallest possible file for sharing photos. PNG files will be noticeably larger than the original HEIF.

Does converting HEIF to PNG lose quality?

No. PNG is lossless, so it preserves the decoded image exactly. It cannot restore detail that HEIF already discarded, but it adds no further loss.

Why is the PNG much bigger than the HEIF?

HEIF uses efficient lossy compression while PNG stores data losslessly. Expect the PNG to be several times larger. That is normal and is the price of zero quality loss.

Will transparency be kept?

Yes. If your HEIF image contains transparent areas, PNG preserves them via its alpha channel. JPG cannot do this — it would fill transparency with a solid color.

Are my files uploaded to a server?

No. Everything runs locally in your browser via WebAssembly. Your images never leave your device.

Does this read Samsung HEIF files too?

Yes. HEIF from iPhone (HEIC) and the high-efficiency mode on Samsung/Android phones are both supported.

Can I convert several files at once?

Yes — up to 20 at a time, downloadable as a ZIP.

What is the maximum file size?

100MB per file, far above typical HEIF photo sizes.
