HEIC for photos, PNG for lossless graphics and transparency
In a HEIC vs PNG choice, keep HEIC for efficient photo storage and use PNG when the app needs a lossless image or transparency.
The formats are optimized for different jobs
HEIC is commonly used for efficient photo capture and storage. PNG uses lossless compression and is a standard choice for graphics, screenshots, and images that need transparency.
A photographic image can be saved as PNG, but the file may be much larger than a compressed photo format.
HEIC vs PNG at a glance
A practical comparison for photos, graphics, and transparency.
| Decision point | HEIC | PNG |
|---|---|---|
| Compression | Common photo workflows use efficient modern lossy compression. | Lossless compression. |
| Transparency | HEIF can carry alpha/auxiliary image information when supported. | PNG has direct, widely supported alpha transparency. |
| Typical use | Camera photos and efficient photo storage. | Graphics, screenshots, UI assets, and transparent images. |
| Compatibility | Good on many modern devices but uneven in some software. | Very broadly supported across browsers and image software. |
What happens to file size?
PNG can be much larger for photographic images because it preserves pixel data losslessly. The exact difference depends on the image. For graphics with flat colors or transparency, PNG may be a natural fit regardless of size.
Which should you use?
Keep HEIC when your photo apps support it. Use PNG when an app asks for PNG, you need a lossless copy, or transparent pixels are important.
If you only need broad photo compatibility and do not need transparency, JPG is often a smaller and more common converted output than PNG.
For HEIC vs PNG, the most useful question is whether you need an efficient photo file or a lossless PNG copy for a specific app or asset.
To check the picture without changing it, open the HEIC viewer.

PNG does not recover detail missing from the HEIC
Converting HEIC to PNG avoids an additional lossy PNG encoding step, because PNG itself is lossless. But it cannot restore image information that was already absent from the HEIC source.

Frequently asked questions
Short answers to common comparison questions.
PNG is lossless, but converting an existing HEIC to PNG cannot restore detail that is not in the source.
Yes. PNG supports alpha transparency.
Use PNG when an app requires it, you need transparency, or you want a lossless raster copy. For ordinary photo compatibility, JPG is often more practical.
