Apple introduced HEIC in 2017 to save storage and improve quality. It works great inside the Apple ecosystem — and creates headaches outside it. Here's when to convert.
If you own a modern iPhone, you've probably been frustrated by HEIC files at least once. You email a photo to someone on Windows, and they can't open it. You upload a vacation picture to a website, and it's rejected. You drag a photo to your old computer, and it shows up as an unknown file type.
This is a strange situation. Photos used to be a solved problem — JPGs worked everywhere. So why did Apple change?
HEIC stands for High Efficiency Image Coding. It's based on the HEIF (High Efficiency Image Format) standard, which is part of the same MPEG family that produced the H.265/HEVC video codec.
Compared to JPG, HEIC is dramatically better at two things:
Apple introduced HEIC with iOS 11 in 2017. Since then, every iPhone (and iPad) defaults to HEIC for photos taken with the built-in camera.
The problem is that HEIC is much newer than JPG, and the world hasn't caught up:
The result: HEIC works great if you only share photos with other Apple users. The moment you need to share more broadly, you hit friction.
You can tell iPhone to save photos as JPG instead of HEIC. Go to:
Settings → Camera → Formats → "Most Compatible"
This changes future photos to JPG. Existing HEIC photos are not affected. You'll lose the storage and quality benefits, but everything you take from now on will work everywhere.
Keep HEIC as the default (you save space and get better quality) but convert when you specifically need to share. Our HEIC to JPG converter handles this in your browser — no upload, no software install, no Apple ID.
This is the better option for most people. You keep the benefits of HEIC for personal storage and only convert the specific photos you need to share with non-Apple users.
iOS is actually pretty smart about this. In some situations it auto-converts HEIC to JPG for you:
But this isn't reliable across every app and situation. When in doubt, convert manually.
Open our HEIC converter in Safari. Tap the dropzone, pick photos from your library, get JPGs out. No upload — conversion happens on your phone.
Transfer the HEIC files to your computer (via cable, AirDrop, email, or cloud), then drop them into the same converter. Works on Windows, Mac, and Linux.
Photos in iCloud download as HEIC by default. You can choose to download as JPG by going to iCloud.com → Photos → Select photos → Download → "Most Compatible."
Converting HEIC to JPG is mostly lossless (HEIC is already lossy, so the JPG conversion at quality 90+ is visually identical), but you lose some metadata:
For most casual sharing, none of this matters. The visual photo is preserved. The metadata losses only matter if you were specifically using those features.
If you almost never use Live Photos, never use Portrait mode for the depth data, and frequently need to share photos with non-Apple users, yes — switch your iPhone to JPG. The friction reduction is worth more than the storage savings.
If you live in an Apple ecosystem (iPhone, iPad, Mac, Apple TV, sharing only with other Apple users), keep HEIC. You save real storage space and get higher image quality.
If you're mixed (some Apple users, some not), keep HEIC and convert when needed. That's the best of both worlds.
