When you convert an iPhone photo, you usually reach for JPG — small and universal. But JPG throws away a little data every time it saves, which matters if you plan to edit the image, archive it, or need it pixel-perfect. For those cases, PNG is the right destination: it’s lossless, so your converted file is an exact copy of the source. Here’s how to convert HEIC to PNG without losing a thing.
What “lossless” actually means here
There’s an important nuance. HEIC itself is a lossy format — your iPhone already compressed the photo when it saved it. Converting to PNG doesn’t magically restore detail that HEIC discarded at capture. What “lossless conversion” means is this: the converter decodes the HEIC and saves the result without adding any new compression artifacts.
In other words:
- HEIC → PNG introduces zero additional loss. The PNG is a perfect copy of the decoded HEIC image.
- HEIC → JPG introduces a small, usually invisible, additional loss because JPG re-compresses.
So if your goal is “don’t degrade the image any further than it already is,” PNG is the format that guarantees it.
How to convert HEIC to PNG losslessly
The simplest, most private method runs entirely in your browser. Our HEIC to PNG converter preserves every pixel:
- Open the converter in your browser on any device.
- Add your HEIC file(s). Drag them in or use the picker — single files or a whole batch.
- Convert. The image is decoded and written as PNG on your device — nothing is uploaded to a server.
- Download the PNG, or grab a ZIP if you converted several.
That’s it. The output is a lossless PNG, identical to the source image, with any transparency preserved.
Why PNG (and when transparency matters)
PNG has two qualities that make it the go-to for fidelity:
- Lossless compression — the saved file is pixel-for-pixel identical to the decoded image.
- Full alpha-channel support — it keeps transparency intact, where JPG would flatten it to a solid color.
That second point is crucial if your HEIC contains a cutout, logo, or any transparent area. Convert it to JPG and the transparency is gone for good; convert it to PNG and it survives. We dig into this in does HEIC support transparency and alpha channel.
The trade-off: file size
PNG’s fidelity comes at a cost. Because it’s lossless and stores far more data than HEIC’s efficient compression, PNG files are usually several times larger than the original HEIC. A 2 MB HEIC might become an 8–12 MB PNG. That’s normal and expected — you’re paying in size for an exact copy.
If file size matters more than perfect fidelity (for example, posting online or emailing), JPG is the better pick. Our HEIC to JPG converter gives you a small, universal file with only a tiny, invisible quality loss. For a side-by-side of the trade-offs, see does converting HEIC to JPG reduce quality.
When to choose PNG over JPG
Reach for PNG when:
- You’ll edit the image and re-save it multiple times (each JPG save would compound loss; PNG never degrades).
- The image has transparency you need to keep.
- You’re archiving a master copy and want maximum fidelity.
- You need a screenshot-sharp result with crisp text or lines.
Reach for JPG when the file is for sharing, uploading, or storage savings and a microscopic quality loss is fine.
The bottom line
To convert HEIC to PNG without losing quality, use a converter that decodes and re-saves the image without re-compressing it — which is exactly what a lossless PNG export does. Our browser-based HEIC to PNG converter produces a pixel-perfect copy on your device, transparency and all, with nothing uploaded. Just remember the trade-off: PNG files are larger, so use them when fidelity matters and JPG when size does.
