heic → png
Convert HEIC to lossless PNG — with zero quality loss and zero uploads.
When you need a lossless result, PNG is the right target for HEIC photos. Lossy compression is thrown away entirely; every pixel that survived the HEIC encode is preserved exactly. That makes PNG the correct choice when a photo will be composited into a design, masked, colour-profiled or re-edited — but be aware the resulting file is usually three to six times larger than a JPG.
100% client-side — your files never leave your device
Conversion runs locally in your browser using Canvas and WebAssembly. There is no upload step, no server processing and no file storage. Disconnect from the internet and this page still works.

Side by side
Here is how the two formats differ. Use it to decide whether converting is worth it, and which one to pick if you have a choice.
| Attribute | HEIC.heic | PNG.png |
|---|---|---|
| Full name | HEIC (High Efficiency Image Container) | PNG (Portable Network Graphics) |
| Compression | Lossy | Lossless |
| Transparency | No | Yes |
| Browser support | Limited | Universal |
| Typical file size | 2.6 MB | 8.1 MB |
| Best for | iPhone and iPad camera originals | Lossless editing and compositing |
The guide
Both formats start from the same decoded image; the difference is how they store it. PNG uses lossless DEFLATE compression, so re-opening the file gives you bit-identical pixels and it supports a full 8-bit alpha channel. JPEG uses lossy DCT compression, discarding detail your eye may not notice but a machine certainly will. If your workflow involves masks, layers, or matching a brand colour exactly, PNG is the only correct answer.
Expect a 12-megapixel iPhone photo to grow from about 2.5 MB as HEIC to 6–9 MB as PNG. That is normal and unavoidable: PNG cannot throw away any information. If file size matters more than losslessness, use the HEIC to JPG converter instead — it is the better choice for email, web upload and social media.
HEIC itself does support an alpha channel, and this converter preserves it when present. However, iPhone photos are almost always opaque, so a PNG from a camera roll will have no transparent regions. Transparency mainly matters for screenshots and graphics exported to HEIC by design tools.
