HEIC to JPG on Windows.
Nothing to install.
Windows still can't open iPhone photos out of the box. Skip the codec download — convert in your browser instead, with the photos never leaving your PC.
Short answer: open toolpantry.app/heic-to-jpg in any browser on the PC, add the photo, keep quality at 85%, and download the JPG. No codec, no app, no upload.
By the Tool Pantry team, October 2026. Measured with Chrome 130 on macOS using a 1440×2200 test image; the same page runs in Edge or Chrome on Windows.
The steps
- On the PC, open your browser and go to toolpantry.app/heic-to-jpg.
- Drag the .heic file in, or tap Choose a HEIC photo. The file usually arrives in Downloads or Pictures after AirDrop, iCloud, or a USB cable.
- Leave quality at 85%. If the JPG needs to be smaller, step down to 60–75%.
- Download the JPG. The original HEIC stays where it was, untouched.
Why Windows makes this harder than it should be
HEIC is a container around HEVC — the same codec family as 4K video. Windows doesn't decode it natively; you're expected to install "HEIF Image Extensions" from the Microsoft Store, which is paid on some builds and still won't make every app cooperate. Older Office versions, and plenty of upload forms, just refuse the file.
The browser route sidesteps all of that. The decoder is part of the web page — about 1.3 MB, downloaded once — and it runs on your machine. Nothing gets installed, nothing gets uploaded.
Our test, with real numbers
We took a 165.6 KB HEIC photo (1440×2200) and converted it at four quality levels. Each conversion took about half a second.
| Quality | JPG size | Good for |
|---|---|---|
| 60% | 146.9 KB | Upload limits, email attachments |
| 75% | 180.4 KB | Everyday sharing |
| 85% (default) | 212.0 KB | Keep-forever copies |
| 95% | 310.3 KB | Printing, archival |
One thing to notice: even the smallest JPG here is close to the HEIC's own size, and at 85% the JPG is actually bigger than the file it came from. That's normal — HEIC compresses better, which is exactly why Apple uses it. You're trading some bytes for a file that opens everywhere. If size matters more than fidelity, 60% is the honest choice; the difference is hard to see on a laptop screen.
Keep in mind
Burst photos and Live Photos contain several images; the tool converts the primary one. And if you'll do this often, there's a setting worth knowing: on the iPhone, Settings → Camera → Formats → Most Compatible makes the camera shoot JPGs directly. It costs storage on the phone, so most people convert on demand instead — which is what this tool is for.
Need a lossless file for editing? HEIC to PNG keeps every pixel. Bundling photos into one document instead? That's HEIC to PDF.
Do I need the HEIF extension from the Microsoft Store for this?
No. The decoder ships with the web page itself (about 1.3 MB, downloaded once) and runs in your browser. Nothing to install on Windows.
Why is the JPG bigger than the HEIC?
HEIC compresses more efficiently — that is why Apple uses it. Converting trades some size for universal compatibility. Drop the quality to 60–75% if the size matters.
Is this free, and are my photos uploaded?
Free, no account. And no — the conversion runs on your PC. The photos never leave it.
Can I convert several photos at once?
One photo per pass, a few seconds each. For a whole camera roll, convert them as you need them — or check the iPhone camera format setting described above.
