How to Convert HEIC to JPG on Windows (Without Installing Anything)

Since iOS 11, iPhones have defaulted to HEIC (High Efficiency Image Format). It's half the size of JPG at the same visible quality — great for iCloud storage. Terrible for sharing with anyone who isn't also on an Apple device. Modern Windows can open HEIC natively, but only if you've paid £0.99 for Microsoft's HEVC codec extension from the Microsoft Store. Older Windows machines and most CMS platforms just error out.

Which is why the conversion request keeps coming up — you're not doing anything wrong, HEIC just isn't built for anyone outside the Apple ecosystem.

Skip installing anything. Open the HEIC to JPG converter, drop the file in the box, and download the JPG. The whole thing takes less than five seconds on a fast connection. Your file is TLS-encrypted on the way up, processed on an isolated worker, and deleted from our servers within 30 minutes. Nothing sits around.

If you've got a batch — say, a folder from a wedding you're trying to share with the whole family — the tool takes up to 20 files at once. Filenames stay the same, just with .jpg on the end.

Windows 10 and 11 will open HEIC files if you install HEIF Image Extensions from the Microsoft Store. That gets you a preview but doesn't convert anything. To actually save as JPG:

Once the codec extension is installed, open the HEIC file in the Photos app, click the three-dot menu in the top right, choose "Save as", and pick JPG from the format dropdown. It works, but you're doing it one file at a time. The codec download itself costs a small fee — Microsoft charges £0.99 for the HEVC decoder that HEIC needs.

If you've got a phone-full of photos that all need converting, doing them one at a time is painful. Your options:

• Online batch: drop up to 20 at once into the converter, download as a ZIP. Free tier caps you at 10 MB per file — enough for iPhone photos.
• Turn HEIC off on the phone: Settings → Camera → Formats → Most Compatible. Every new photo saves as JPG from that point on. Old photos stay HEIC.
• Change AirDrop settings: Settings → Photos → Transfer to Mac or PC → Automatic. iPhone converts HEIC to JPG when the destination doesn't support HEIC natively.

UK visa portals, US government sites, university applications, insurance uploads — none of these accept HEIC. If you're trying to submit a photo and the site keeps saying "unsupported format," this is almost always the reason. Convert to JPG first, upload the JPG, done.

Same story for WordPress, Squarespace, Wix, and most other CMS platforms. HEIC uploads work only if the site owner has installed a specific plugin. JPG works everywhere without asking.

By default, no — the converter preserves EXIF metadata (camera model, date, GPS coordinates, exposure settings). If you're about to post the photo somewhere public, that's something to think about. GPS in a holiday photo tells anyone with basic tools exactly where you were and when.

Most conversion tools have an option to strip metadata during conversion. Worth using if the photo is going somewhere public. Worth keeping if the photo is going into your personal archive.

HEIC to JPG isn't a quality decision — it's a compatibility fix. Every non-Apple system on the planet reads JPG. Not everything reads HEIC. If a file needs to leave your Apple universe, convert it before it goes. For a one-off, the browser tool is faster than anything you can install. For a big batch, flip the phone setting so new photos save as JPG going forward.
