Quick Answer
HEIC gives smaller, higher-quality photos on an iPhone, but few systems outside Apple's support it. JPG works everywhere. Convert HEIC to JPG when you share photos with other people or upload them to a platform that doesn't support HEIC.
HEIC vs JPG Comparison
| Feature | HEIC | JPG |
|---|---|---|
| Compression | HEVC (High Efficiency) | DCT-based lossy |
| File size | ~50% smaller than JPG | Larger |
| Quality | Better at same file size | Good, but less efficient |
| Transparency | Yes | No |
| Browser support | Safari, Chrome, Firefox, Edge | Universal |
| Windows support | Requires extension | Native |
| Android support | Android 9+ | Universal |
| Social media | Mostly supported | Fully supported |
| Default on | iPhone (iOS 11+) | Most cameras and phones |
| Editing support | Limited software | Universal |
When to Use HEIC
- iPhone photography, for smaller files with better quality on Apple devices
- Saving storage space: you can keep roughly twice as many photos at the same quality
- Moving photos between iPhone, Mac and iCloud
- Burst photos and Live Photos, since HEIC supports sequences that JPG cannot
- Photos with depth data, because HEIC keeps Portrait mode depth maps
When to Use JPG
- Sharing photos widely, since any device, app or website can open them
- Uploading to older platforms, as some websites and systems don't accept HEIC
- Professional editing, because most editing software handles JPG natively
- Email attachments that recipients can open without special software
- Windows, where JPG works without installing extra codecs
Compatibility in Practice
Most people convert HEIC to JPG for compatibility. Support is improving (modern Chrome, Firefox and Edge can display HEIC), but many situations still call for JPG:
- Emailing photos to someone on an older computer
- Uploading to certain websites, forums, or government portals
- Using photo editing software that doesn't support HEIC
- Printing photos at retail kiosks
- Sharing with Android users on older OS versions
Quality and File Size
HEIC gets its smaller files from the HEVC (H.265) codec, which compresses much more efficiently than JPG's DCT-based method. In practice, a photo that takes 10MB as a JPG might take 5-6MB as a HEIC at equivalent visual quality.
For most users the difference only matters when storage is limited or when uploading many photos over a slow connection.
