HEIC wins on efficiency. JPEG wins on compatibility. Which is better for you depends on where your photos end up.
The comparison at a glance
| HEIC | JPEG | |
|---|---|---|
| File size | Roughly half of a JPEG at similar quality | Larger |
| Colour depth | Up to more than 8 bits per channel | 8 bits |
| Transparency | Supported | Not supported |
| Multiple frames, depth data | Supported | Not supported |
| Opens on Windows | Needs extensions | Yes, out of the box |
| Accepted by web forms | Often rejected | Almost always accepted |
| Editing software | Modern tools only | Everything |
| Introduced | 2015 standard, iPhone default since 2017 | 1992 |
Does HEIC look better?
At equal file sizes, HEIC generally preserves more detail and shows fewer blocky artefacts than JPEG, because its compression is more advanced. In everyday viewing the difference is subtle. The practical win is the smaller file, not a dramatic quality jump.
When to keep HEIC
- Your photo library lives mainly on Apple devices and iCloud.
- Storage is tight and you do not need to share files outside Apple apps.
When to use JPEG
- You send photos to other people, or upload them to forms, marketplaces and job sites.
- You work on Windows or with older software.
- You want one format that never causes questions.
Switching between them
Convert HEIC to JPEG with the HEIC to JPG converter. Converting the other way is possible with JPG to HEIC, but it recompresses an already compressed image, so only do it when you have a reason, and keep the originals.
