Convert HEIC to PNG
Choose PNG over JPG when the photo is about to be edited: PNG is lossless, so layers of retouching and re-saving will not stack compression artifacts on top of HEIC’s own. The files come out large — that is the nature of lossless — but for a photo heading into Photoshop or GIMP it is the right starting point.

How it works
Select or drag in the HEIC shots you plan to edit — bursts arrive as separate files, and all of them can go in together.
There’s no quality dial to think about: PNG output is lossless, so every pixel of the decoded photo is kept exactly.
Download the PNGs individually or zipped, then open them in Photoshop, GIMP or any editor without a codec in sight.
HEIC vs PNG
This pair isn’t really a contest — it’s a handoff. HEIC is where the photo lives efficiently; PNG is where it goes to be worked on, because retouching a lossy format directly stacks fresh compression on every save. Pay the 10× size cost only for shots headed into an editor.
| HEIC | PNG | |
|---|---|---|
| Compression | Lossy | Lossless |
| Transparency | No | Yes (full alpha) |
| Animation | No | No |
| Support | Apple devices; patchy elsewhere | Universal — every browser, editor and OS |
| Best for | iPhone camera storage | Logos, screenshots, graphics with transparency |
Frequently asked questions
No — that is the whole reason I built this. The conversion runs in your browser using WebAssembly, so your files never leave your device; there is no server in the loop at all. It also means the tool keeps working offline once the page has loaded, and there is no file size limit beyond your device’s memory.
Pick PNG when the image will be edited further — retouching, compositing, repeated saves. Pick JPG when the destination is sharing or uploading and file size matters. PNG preserves every pixel of the decode; JPG re-compresses but is a fraction of the size.
HEIC is one of the most efficient lossy formats there is, and PNG is fully lossless — you are unpacking a highly compressed photo into a format that discards nothing. A 2 MB HEIC becoming a 15–25 MB PNG is normal for a 12-megapixel shot.
Yes — the decode is pixel-exact at the original resolution, whether that is a 12, 24 or 48-megapixel shot. Nothing is resized or cropped. Very large sensors just take a moment longer, since everything runs on your device.
Not on efficiency — a 2 MB HEIC blows up to 15–25 MB as PNG. PNG wins on two other axes: nothing ever degrades it (every save is exact), and everything made since 1996 opens it. So HEIC is the better container for storing photos; PNG is the better container for working on one. Convert the shot you are about to retouch, not the whole camera roll.
Anything you merely want to share or upload — the 10× size increase buys nothing there, and plenty of forms cap uploads below what a 48-megapixel PNG weighs. For those, HEIC to JPG at quality 90 looks identical and stays a tenth of the size. PNG earns its bulk only when an editor will re-save the file repeatedly.
