| Category | HEIC | JPG |
|---|---|---|
| Full name | High Efficiency Image Container | JPEG |
| Introduced | 2017 (iOS 11 default) | 1992 |
| Compression | HEVC - modern, efficient | DCT - old, universal |
| Typical file size | Roughly half of JPEG | Baseline |
| Apple devices | Native | Native |
| Windows / Android | Often needs an add-on | Universal |
| Extra features | Depth maps, Live Photos, 16-bit, multiple images | Single 8-bit image |
Why your iPhone produces these at all
Since iOS 11, Apple devices default to HEIC because it stores a visually comparable photo in roughly half the space of JPEG. On a phone full of thousands of photos that is a genuinely large saving, and it also lets a single file carry things JPEG cannot: depth maps for portrait mode, the short video of a Live Photo, and higher bit depth.
Why it will not open on a PC
HEIC files use HEVC compression, which is covered by patent licensing. That has made support outside Apple slow and inconsistent - Windows can display HEIC but historically required a codec from the Microsoft Store, and support across Android devices, older software and web applications is uneven. JPEG has no such encumbrance, which is the whole reason it is everywhere.
Quality is not really the argument
At the settings a phone actually uses, you will not see a quality difference between a HEIC and a good JPEG of the same photo. The difference is size and features, not visible fidelity. Anyone telling you a HEIC looks obviously better at normal viewing sizes is overselling it.
The setting that avoids the problem entirely
On an iPhone, Settings → Camera → Formats → Most Compatible switches the camera to JPEG permanently. You lose the space saving and the depth-map features, and you stop ever having this problem again. If you mostly share photos with people on other platforms, that is usually the right trade.
Converting the ones you already have
Our HEIC to JPG and HEIC to PNG converters run in your browser and load a decoder only when you actually pick a HEIC file, so the page stays light for everyone else. Worth knowing: only Safari can decode HEIC natively, so on Chrome, Firefox and Edge a WebAssembly decoder does the work - which takes a moment or two per photo but means it works on Windows and Android without installing anything.
Our Verdict
Keep HEIC if you live inside the Apple ecosystem and want the storage saving. Switch your camera to Most Compatible if you regularly send photos to Windows, Android or web services, because the space you save is not worth the friction. For photos you already have, convert to JPG at the point of sharing rather than converting your whole library.
