You copied photos off an iPhone, double-clicked one on your PC, and Windows shrugged — a grey box, a "can't open this file" message, or just a thumbnail that never loads. The file ends in .heic, and Windows doesn't always know what to do with it. It's one of the most common photo headaches people hit after switching a phone or sharing pictures across a family, and it has nothing to do with the photo being broken. Here's how to fix it, fastest option first, so you can get back to actually using the picture.
Why Windows chokes on HEIC
HEIC is Apple's default photo format, built on the HEVC codec. Windows ships without that decoder on most installs because of licensing, so the Photos app literally can't read the file. The photo is perfectly fine — your PC just can't decode it yet. If you want the full background, here's what a HEIC file is and why iPhones use it.
You've got two real paths: convert the file to a format Windows already reads, or teach Windows to read HEIC. Most people only need the first.
Method 1: Convert it in your browser (fastest, free)
This is the no-install, no-fuss route, and it works identically on Windows 10 and 11.
- Open our HEIC to JPG converter in any browser.
- Drag your .heic file onto the page, or click to pick it from your folder.
- Download the JPG — it opens in Photos, Paint, Word, email, anywhere.
Want lossless quality or hard edges (screenshots, graphics, text)? Use HEIC to PNG instead. The conversion runs in the browser, there's no account, no watermark, and you can throw a whole batch in at once.
Open any HEIC right now
No codec, no download, no sign-up. Convert your iPhone photo to a standard JPG right in your Windows browser — your file never leaves your device — and open it instantly.
Convert HEIC to JPG →Method 2: Install Microsoft's HEIC codec
If you deal with HEIC constantly and want them to just open in the Photos app like any other picture, add the codec.
- Open the Microsoft Store and search for HEIF Image Extensions. Install it (it's free).
- HEIF relies on HEVC Video Extensions for decoding. Microsoft sometimes charges a small fee for that package, and availability varies by region.
- Once both are in, double-click any .heic and it opens in Photos like a JPG.
The downside: it's a couple of installs, the HEVC package isn't always free, and it only helps on that one PC. It does nothing for files you need to email to someone whose computer still can't read HEIC.
Method 3: Let your iPhone hand you a JPG
You can sidestep the whole thing at the source. On the iPhone, open Settings → Camera → Formats and choose Most Compatible. New photos save as JPG, which Windows opens with no extra steps. This won't convert the HEIC photos you already have — only future ones — so it's prevention, not a cure for today's file.
Bonus: turning HEIC into a Windows-friendly document
Often the reason you're wrestling with a HEIC on Windows is that you need to send it somewhere — an expense form, a rental application, a job portal. In that case, skip JPG and go straight to a document. Our HEIC to PDF tool drops each photo onto its own page, and you can merge several HEIC shots into a single PDF. Already have a mix of JPGs and PNGs too? Combine the lot with Images to PDF.
Which method should you pick?
- One-off file, need it now? Convert in the browser (Method 1).
- HEIC every week, want native viewing? Install the codec (Method 2).
- Tired of the problem entirely? Switch the iPhone to Most Compatible (Method 3).
- It's actually paperwork? Convert straight to PDF.
For nine out of ten people, the browser conversion is the answer — it's instant, free, and leaves nothing installed on your machine. The codec route only pays off if you live in HEIC files day after day and want them to behave like ordinary photos in the Photos app. Everyone else is better served by a quick convert-and-go, which also produces a file you can confidently forward to anyone, regardless of whether their computer has ever heard of HEIC.
