Convert JPG to HEIC
JPEG has been the default photo format for thirty years and works everywhere, which is exactly why nobody replaced it sooner. HEIC stores the same picture with far more efficient compression, typically at around half the size. Converting JPG to HEIC is mostly about reclaiming space in a photo library without visibly changing the photos.

How to convert JPG to HEIC

- Choose HEIC as the output. Nothing is uploaded; the work happens on your own machine.
- Pick a destination for the converted copies. The originals stay exactly where they were.
JPG vs HEIC: what actually changes
| JPG | HEIC | |
|---|---|---|
| File size | Baseline | Roughly half, at similar quality |
| Compatibility | Opens literally everywhere | Apple devices natively, elsewhere it varies |
| Transparency | No | Yes |
| Compression | 1990s design | Modern, video-derived |
| Good for | Sending to anyone at all | Storing a large library efficiently |
When to convert, and when not to
Convert JPG to HEIC when storage is the problem: a phone that is full, a photo library that has outgrown its drive, or an archive you would like to halve. It makes most sense when the photos live in an Apple ecosystem where HEIC is the native format anyway.
Do not convert photos you need to send to unknown recipients or upload to older systems. JPEG's compatibility is unmatched and that is its real value. Also remember both formats are lossy, so converting an already-compressed JPEG means a second generation of loss.
Why not just use an online converter?
A JPEG straight from a camera or phone carries EXIF: the device, the settings, the timestamp, and often GPS coordinates accurate to a few metres. Converting on your own machine means that record is never handed to an upload service, and you can drop the location data on the way through if you would rather it did not follow the photo around.
Questions
Is HEIC really half the size?
For typical photographs, roughly, at comparable visual quality. Flat graphics and images with large plain areas benefit less, because JPEG already handles those reasonably well.
Will converting a JPEG lose quality?
Slightly. The JPEG has already been compressed once, and re-encoding adds a second pass. It is usually not visible, but converting back and forth repeatedly will degrade the image.
Will the result open on an iPhone or Mac?
Yes. HEIC is what Apple devices shoot in by default, so the files land in Photos, Messages and AirDrop with no extra step.
Does this need an internet connection?
No. Conversion runs locally, so it works offline and nothing is sent anywhere.
