How to use HEIC to PNG

- 2Click Convert to PNG; each photo is decoded and re-encoded losslessly on your device.
- 3Download each PNG, or download them all as a ZIP.
How it works
Drop your HEIC files in and each one is decoded on your device and re-encoded as a PNG. PNG is lossless, so no additional quality is discarded during the conversion.
Nothing is uploaded — the conversion uses your browser's own processing power.
When to choose PNG over JPG
Pick PNG when you need pixel-perfect quality with no compression artefacts, when you'll edit the image repeatedly, or when you need transparency preserved.
PNG files are larger than JPG for photographs. If your goal is a small, shareable file, HEIC to JPG is usually the better choice.
Quality and detail
Because PNG stores every pixel exactly, the output keeps the full detail decoded from the HEIC. EXIF orientation is applied so photos aren't rotated.
Expect PNG files to be several times larger than the original HEIC — that's the cost of lossless storage.
Frequently Asked Questions
Are my images uploaded to a server?
No. Every conversion runs locally in your browser using your device's own processor. Your images never leave your computer or phone, and nothing is stored on our servers.
Is PNG really lossless?
Yes. PNG compression rearranges data without discarding any of it, so the decoded image is identical to what came out of the HEIC. There's no quality slider because there's no quality to trade away.
Why is my PNG larger than the HEIC?
HEIC uses efficient lossy compression, while PNG stores every pixel exactly. Larger PNGs are expected. If size matters more than perfect fidelity, convert to JPG instead.
Can I convert several images at once?
Yes. Drop or select multiple files and they'll be processed in a controlled queue so your browser stays responsive. Each file shows its own progress, and you can download them individually or all together as a ZIP.
Is it free, and are there limits?
It's completely free with no account required. Because processing happens on your device, there's no per-file upload limit — the practical ceiling is your device's available memory. You can batch many files and download them as a single ZIP.
