HEIC vs JPG
HEIC wins on file size and quality. JPG wins on compatibility. A HEIC is about half the size of a JPG at the same visual quality, but only Apple devices and recent Windows installs (with extra codecs) read HEIC natively. JPG opens on literally everything.
Quick comparison
| HEIC | JPG | |
|---|---|---|
| Year invented | 2015 | 1992 |
| File size (12 MP photo) | 3–4 MB | 6–8 MB |
| Image codec | HEVC (H.265) | JPEG (DCT) |
| Color depth | Up to 16-bit | 8-bit only |
| Transparency | Yes | No |
| Multiple images per file | Yes (burst, Live Photo) | No |
| Apple device support | Native since iOS 11 / macOS High Sierra | Always |
| Windows support | Requires Microsoft Store codec | Native |
| Android support | Android 10+ on most phones | Native |
| Web browser support | None natively | All browsers |
| Patent status | HEVC patent pool (licensed) | Royalty-free since 2017 |
When to use HEIC
- You're staying inside Apple's ecosystem
- You're tight on iCloud storage
- You want to keep Live Photo motion, depth, or HDR metadata
- You're a photographer who wants 10-bit or 12-bit color
When to use JPG
- You're sharing with Windows or Android users
- You're uploading to a website that doesn't accept HEIC (most don't)
- You're emailing photos to anyone
- You're submitting to a school portal, work portal, or government form
- You're printing
- You want maximum compatibility, period
The "have your cake" approach
Leave your iPhone Camera setting on HEIC (default). Keep iCloud storage savings. Convert to JPG only when you actually need to send a photo somewhere non-Apple. Use the free browser converter — no upload, no signup, batch supported.
Quality test: HEIC to JPG round-trip
The most common worry: "If I convert my HEIC photos to JPG, am I going to ruin them?"
Short answer: no, not at any reasonable quality setting.
The full chain is: original HEIC (decoded to pixel data) → JPG encoder. The decode step is lossless. The encode step adds JPG compression once. At High quality (95%), JPG artifacts are below the threshold most screens can show.
Where you'd see a difference: shooting 10-bit HEIC, converting to 8-bit JPG, then heavily editing the shadows in Lightroom. Most people don't do that. If you do, use HEIC to PNG (lossless) instead.
What HEIC actually saves over JPG
- Intra-frame prediction: HEVC predicts pixel values from nearby pixels before encoding, so it stores the difference instead of the raw value. JPEG just stores 8x8 blocks independently.
- Variable block sizes: HEVC uses 4x4 up to 64x64 blocks adaptively. JPEG is fixed 8x8.
- Better entropy coding: HEVC uses CABAC; JPEG uses Huffman.
- Container metadata: HEIF can store multiple images, depth maps, and EXIF in one file efficiently.
Net effect: ~50% smaller files at the same perceived quality. Apple's marketing claim is conservative; you can sometimes get 60%+ on smooth photos like landscapes.
