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.
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.
