HEIC and PNG Compatibility
PNG is often easier to use than HEIC across non-Apple applications and workflows.
HEIC Photos from iPhone and Apple Devices
Many iPhones save photos as HEIC when High Efficiency capture is enabled. Converting a copy can make the image easier to use outside Apple-focused workflows.
Image quality when converting HEIC to PNG
Output quality depends on the HEIC source and selected PNG settings.
File size after conversion
Final file size depends on the source photo and selected PNG settings.
What happens to image metadata?
Re-encoding can remove or change embedded metadata. Use the Strip metadata option when you want the converted copy to exclude embedded information.
Private image conversion
HEIC is decoded locally when possible. Some files may require a compatibility path if browser decoding is unavailable.
Compression presets
Presets automatically adjust compression and image size depending on how the converted image will be used.
| Preset | Compression | Max Dimensions | Typical File Size | Best For |
|---|---|---|---|---|
| Web | Medium | 1920px | 200KB – 800KB | Websites, blogs, landing pages |
| Social | Medium-High | 1200px | 100KB – 400KB | Instagram, Facebook, LinkedIn |
| High | 1200px | 50KB – 200KB | Email attachments and quick sharing | |
| Low (Highest Quality) | No resize | 1MB+ | Printing photos or marketing materials |
Actual file size depends on the original image resolution, source format, image content, and selected settings.
Common HEIC to PNG conversion issues
