How to Convert HEIC to PNG
Need a lossless version of your iPhone photos? Converting HEIC to PNG gives you a pixel-perfect copy in a format that works everywhere — and preserves any transparency data your original image might contain. imageconvert.co decodes your HEIC files using a WebAssembly decoder running entirely in your browser, then encodes them as PNG without any quality loss in the conversion step.
HEIC vs PNG: What's the Difference?
| Feature | HEIC | PNG |
|---|---|---|
| Compression | Lossy (based on HEVC codec), very efficient | Lossless — no data is discarded |
| File size | Very small (advanced compression) | Larger — typically 3-5x bigger than HEIC |
| Transparency | Supported (alpha channel) | Supported (alpha channel) |
| Browser support | Safari only | Universal — every browser since the early 2000s |
| Best use case | On-device storage on Apple products | Graphics, screenshots, images needing lossless quality |
Keep in mind that since HEIC uses lossy compression internally, converting to PNG won't magically restore lost data — it preserves exactly what the HEIC file contains, just in a universally compatible lossless wrapper.
How to Convert HEIC to PNG
- Drop or click to upload your HEIC files — batch conversion is fully supported
- Files are decoded and re-encoded as PNG automatically, entirely in your browser
- Download your PNG files individually or as a ZIP archive
Frequently Asked Questions
Will my HEIC to PNG conversion be lossless?
The conversion step itself is lossless — PNG preserves every pixel exactly as decoded from the HEIC file. However, since HEIC uses lossy compression at capture time, the original sensor data has already been compressed. You get a perfect representation of the HEIC content, stored in a lossless format.
Why are my PNG files so much larger than the HEIC originals?
PNG uses lossless compression, which produces significantly larger files than HEIC's lossy approach. A 2MB HEIC photo might become 8-12MB as a PNG. If file size matters more than lossless quality, consider converting to JPG or WebP instead.
Does HEIC to PNG preserve transparency?
Yes. If your HEIC file contains an alpha channel (transparency data), the PNG output will preserve it. Standard iPhone photos don't use transparency, but some edited images or Portrait mode depth maps might.
When should I choose PNG over JPG for my HEIC conversion?
Choose PNG when you need pixel-perfect quality (like screenshots or graphics), need transparency support, or plan to edit the image further (each JPG save introduces more compression artifacts). Choose JPG when file size is the priority and you're just sharing photos.
