HEIC vs JPG: Which Should You Actually Use?

If you own an iPhone made since 2017, your photos are probably HEIC files. If you have ever tried to send one to a Windows user, you have met the downside. The honest answer to "which is better" is that HEIC wins on technical merit and JPG wins on everything else.

Where HEIC is genuinely better

• Roughly half the file size at equivalent visual quality, thanks to a far more modern compression scheme.
• 16-bit colour depth against JPG's 8-bit, which means smoother gradients and far more latitude when editing exposure.
• Transparency support, which JPG lacks entirely.
• Multiple images in one file, which is how Live Photos and burst sequences are stored.
• Depth maps, enabling portrait-mode background editing after the fact.

On a phone holding 20,000 photos, halving storage is not a marginal benefit.

Where JPG wins, decisively

One thing: everything opens it. JPG has been universally supported since 1992. Every operating system, browser, printer, photo frame, email client and upload form handles it without thought.

HEIC arrived in 2017 carrying patent licensing requirements, which made other vendors slow to adopt. The practical result is a long list of places your photo will not open: older Windows installations without the paid extension, many Android devices, a great many web upload forms, older Photoshop and Office versions, most email previews, and a surprising number of print services.

Compatibility beats elegance in daily use.

A practical rule

• Keep HEIC for photos that live on your phone and in your own Apple ecosystem. You get the storage saving and the editing headroom with no friction.
• Convert to JPG whenever a photo is leaving that ecosystem — emailing, uploading to a form, sending to a Windows or Android user, printing, or posting anywhere that might not cope.

This is better than switching your camera permanently, because you keep the benefits and pay the compatibility cost only when it actually arises.

If you would rather not deal with it at all

Switch the camera to JPG: Settings → Camera → Formats → Most Compatible. New photos are captured as JPG from then on. Existing photos stay HEIC.

There is a second setting worth knowing. Under Settings → Photos, at the bottom, Transfer to Mac or PC set to Automatic makes the phone convert to JPG during cable transfer.

Converting without handing over your location

One consideration specific to photographs: the EXIF metadata in an iPhone photo includes the exact GPS coordinates and timestamp of where it was taken. Uploading a batch of family photos to a free converter transmits a precise record of where you live and when you were away from home.

Our HEIC to JPG converter decodes the image inside your browser using a WebAssembly build of libheif, so the photographs and their location data never leave your device. There is no file count limit, and batches download as a ZIP. For more detail, see our full HEIC guide.
