HEIC to PNG Converter – Convert iPhone HEIC Photos to PNG Free

iPhones save photos as HEIC, and half the world still cannot open them. This converter turns a HEIC photo into a PNG — the lossless format that keeps every pixel exactly as the camera captured it. Everything runs in your browser: no uploads, no sign-up, no waiting for a server.

Already have our HEIC to JPG converter? That one is for small, easy-to-share files. This is the twin for when quality matters more than size: PNG output, same trusted decoder, same full resolution.

How to convert HEIC to PNG

Click the file box and choose a .heic (or .heif) photo.
Click Convert to PNG. The first conversion loads the decoder and can take a few seconds on big photos.
Check the preview and file size, then click Download PNG.

A worked example, with the numbers

Take a standard iPhone photo: 4032 × 3024 pixels, saved as a 3.1 MB HEIC. The PNG that comes out is around 14–18 MB — five times the HEIC, because PNG stores the picture losslessly instead of throwing data away. Dimensions are identical, the orientation recorded by the phone is applied so nothing opens sideways, and unlike a JPG there is no quality setting to get wrong: PNG is exact.

PNG or JPG from a HEIC?

Choose PNG when you will edit the photo further, crop into it, print it, or archive it. Every edit-and-resave cycle with JPG degrades the image a little more; PNG does not.
Choose JPG (use our HEIC to JPG converter) when you just need to view, email or upload the photo somewhere. Files are roughly ten times smaller.
Screenshots and graphics hiding in your camera roll as HEIC also belong in PNG: text and sharp edges stay crisp.

How the decoding works

Safari can decode HEIC natively, so there the tool uses the browser itself. In Chrome, Edge and Firefox, the page loads the open-source heic2any decoder (built on libheif, the reference HEIC library) and decodes the file locally in your browser tab. Either way the photo never leaves your device.

Honest limitations

PNG files are big — a converted photo can be 10–20 MB, and some upload forms cap files below that. Convert one photo at a time; Live Photos convert using their still frame. EXIF data such as GPS location is not carried into the PNG. If a conversion fails on an older phone, try a desktop browser, where the decoder has more memory to work with.

iPhone settings that prevent the problem

If you convert HEIC files every week, two iPhone settings can end the chore. Settings → Camera → Formats → Most Compatible makes the phone shoot JPG directly — larger files, zero conversion, slightly less efficient storage. And Settings → Photos → Transfer to Mac or PC → Automatic converts on the fly when you copy photos to a computer, while keeping HEIC on the phone itself. Neither helps with photos already taken, or with HEIC files other people send you — for those, this page is the fix.

Frequently asked questions

Why is the PNG so much larger than the HEIC?

HEIC compresses photos very aggressively using modern techniques; PNG is an older, lossless format that keeps every pixel. The size jump is the honest price of zero quality loss.

Is my photo uploaded anywhere?

No. Decoding and encoding both happen inside your browser tab. You can load the page, switch to airplane mode, and the conversion still completes.

Can I convert HEIC to PNG on an iPhone?

Yes — Safari decodes HEIC natively, so conversions on iPhone and Mac are the fastest path this tool has.
