If you have ever emailed an iPhone photo and the other person could not open it, you have met HEIC. Apple adopted it because it stores photos at roughly half the size of JPG at the same quality — great for your phone's storage. The problem is compatibility: Windows photo apps, many web upload forms, older devices, and plenty of editing software still cannot read HEIC. Converting to JPG fixes all of that at once, and you can do it without uploading the photo to anyone.
What HEIC is and why it trips people up
HEIC (High Efficiency Image Container) is Apple's wrapper around the HEVC codec. It is efficient, but it is not universally supported the way JPG is. JPG has been the lingua franca of digital photos for decades, so converting to it removes the friction entirely — the resulting file opens in Windows Photos, Paint, Word, every browser, and every upload box.
Step by step: convert in your browser
Open HEIC to JPG. The conversion runs on your device — the photo is not uploaded.
- Open the tool in any modern browser (Chrome, Edge, Firefox, Safari).
- Drop in your HEIC files. Drag one or many
.HEICfiles onto the page, or choose them. - Let it decode. Each photo is decoded and re-saved as JPG locally — no upload, no waiting on a server.
- Download the JPGs. Save them, and they now open anywhere.
On Windows
You do not need Microsoft's paid "HEVC Video Extensions" or any install. Open the tool, drop the files, and you get JPGs that Windows handles natively. This is the simplest fix for the "Windows won't open my iPhone photos" problem.
On Mac
Preview can export HEIC one at a time, but the browser tool is faster for a batch and keeps everything in one place. Drop several photos and download them all as JPG.
JPG or PNG — which should you pick?
For photos, choose JPG: it is smaller and supported everywhere. Choose HEIC to PNG only if you specifically need a lossless copy or transparency, neither of which a normal photo has. If you later need the JPG under a size limit (for an upload form, say), run it through the compressor — also in your browser.
A note on quality and file size
Because HEIC is so efficient, the JPG version of the same photo is usually a little larger. That is normal and the quality difference is invisible in everyday use. If file size matters, compress the JPG afterwards rather than over-compressing during conversion.
Why "without uploading" matters here
The photos people convert are almost always personal — family pictures, screenshots, documents — and iPhone photos frequently carry GPS location data. A browser-side converter decodes and re-saves the image on your own machine, so there is no server copy to worry about. Want to remove the embedded location and camera data too? Run the JPG through Remove Metadata afterwards.
Use the tool: HEIC to JPG — free, runs in your browser where supported, no file is uploaded to a server.
Frequently asked questions
Do I need to install anything to open HEIC on Windows?
No. A browser-based converter turns the HEIC into a JPG that Windows opens natively, so you avoid the paid HEIF extension and any software install.
Will converting HEIC to JPG lose quality?
There is a small, usually invisible quality change because JPG is lossy, and the JPG is often slightly larger than the HEIC for the same photo. For everyday use the difference is not noticeable.
Is my photo uploaded when I convert it?
No. The conversion runs in your browser on your own device, so the photo is never sent to a server. You can verify by going offline after the page loads.
Can I convert many HEIC photos at once?
Yes. Drag multiple HEIC files into the converter and download them all as JPG; each one is processed locally in your browser.
