iPhones save photos in HEIC — Apple’s space-saving format — which looks great on Apple devices but refuses to open on many Windows PCs, older programs and websites that still expect JPG. This converter fixes that in seconds: drop in your HEIC (or HEIF) files and download standard JPGs that open anywhere.
The important part: every conversion happens inside your own browser. Your photos are never uploaded to a server, never stored, and never seen by anyone — unlike most “free” HEIC converters online, which send your private pictures to their servers. You can convert a whole batch at once, choose the JPG quality, and download each result immediately.
How to use it
-
1Select your HEIC files
Tap “Choose HEIC files” and pick one or more .heic or .heif photos, or drag them onto the box. Everything stays on your device.
-
2Let it convert
Each photo is decoded and re-encoded to JPG right in your browser. A thumbnail appears as soon as each one is ready.
-
3Adjust quality if you like
Use the quality slider before converting for smaller files or maximum detail. 90% is a great balance for most photos.
-
4Download your JPGs
Tap download under any photo to save it, and repeat for the rest. The originals on your device are left untouched.
Why This Test Exists
Apple's image and video formats are excellent on Apple hardware and awkward everywhere else. HEIC photos and HEVC video routinely fail to open on Windows, on older software and in web uploads, which is why conversion is one of the most common things people need and one of the most common things sites do badly — usually by uploading your files to a server first.
Getting a Reliable Result
This converter does not. The work happens in your browser: the file is read locally, decoded locally and written back out locally, and nothing is transmitted. That is verifiable rather than promised — open the network inspector while converting and watch nothing leave. It also means the tool works offline once the page has loaded.
Reading the Outcome
Large batches will be limited by your device's memory rather than by us. If a conversion stalls on a phone, try fewer files at a time, or run it on a computer where there is more headroom.
Nothing Leaves Your Device
This tool runs entirely in your browser. There is no upload step, no account, no cookie set for it and no record kept of anything you test — which is a consequence of how it is built rather than a policy you have to trust. It also means it works on any device, on any operating system version, whether or not you are running a beta.
If a test here points at software rather than hardware, that is useful in itself: it means the next step is a beta build or a setting rather than a repair. Our troubleshooting guides cover the common ones, and your device's page sets out what to expect from your specific model on the current release.
Frequently asked questions
How do I convert HEIC to JPG on iPhone without an app?
Open this page in Safari on your iPhone, tap “Choose HEIC files”, select the photos from your library, and download the JPG versions. It works entirely in the browser, so there’s no app to install and nothing is uploaded.
Are my photos uploaded anywhere?
No. The conversion runs locally in your browser using an on-device decoder. Your images never leave your phone or computer, aren’t stored, and aren’t sent to any server — which is why it’s safe for private and personal photos.
Can I convert many HEIC files at once?
Yes. Select multiple files and they’re converted in a batch, each with its own thumbnail and download button. Very large batches take longer because all the work happens on your device.
Is there a watermark or a file limit?
No watermark, no sign-up and no artificial file limit. The only practical limit is your device’s memory for very large batches. The output is a standard JPG that opens on Windows, Android, the web and everywhere else.
Why won’t my HEIC photos open on Windows?
HEIC is Apple’s format; Windows and many apps only added partial support recently, and older software can’t read it at all. Converting to JPG produces a universally compatible file that opens on any device or program.
