Why Windows Can't Open HEIC by Default
HEIC files are compressed using HEVC (H.265), a licensed video codec. Microsoft doesn't bundle a license for that codec into every copy of Windows, so File Explorer, the Photos app, and most other built-in tools have no way to decode a HEIC file's image data. The file isn't broken — your PC just doesn't have the piece it needs to read it yet.
Quick Comparison of All 4 Methods
| Method | Setup Required | Best For |
|---|---|---|
| Microsoft Store codec | Install two free extensions, restart | Permanent fix for regular HEIC files |
| Photos app (after codec) | None — works once codec is installed | Viewing and light editing |
| Convert online (EasyConvertTools) | None — works immediately | One-off files, no install wanted |
| Third-party desktop apps | Download and install an app | Batch conversion, offline workflows |
Method 1: Install the HEIC Codec from Microsoft Store
This is the permanent fix if you receive HEIC files regularly. Open the Microsoft Store, search for "HEVC Video Extensions", and install it (this one occasionally carries a small fee depending on your device). Then search for and install "HEIF Image Extensions", which is free. Restart File Explorer — or just restart your PC to be safe — and HEIC files will start showing real thumbnails instead of blank icons.
Method 2: Use the Photos App After Installing the Codec
Once both extensions from Method 1 are installed, double-clicking a HEIC file opens it directly in the Windows Photos app, exactly like a JPG. You can zoom, rotate, and run basic edits from there. This only works after the codec is installed — without it, Photos will show the same error as File Explorer.
Setting Photos as the Default for HEIC
If HEIC files open in the wrong app, right-click any .heic file, choose
"Open with" → "Choose another app", select Photos, and check "Always use this
app." Future HEIC files will open there automatically.
Method 3: Convert Online with EasyConvertTools (No Install)
If you only need to deal with a HEIC file occasionally, installing two Store apps and restarting your PC is a lot of friction for one photo. Our HEIC Viewer opens any HEIC file directly in your browser tab — drag it in and it displays full-size immediately, with nothing installed and nothing uploaded to a server.
If you want a file you can keep using afterward — attach to an email, upload somewhere, print — convert it instead with our HEIC to JPG converter. It runs entirely client-side, so your photos never leave your device, and you get a JPG you can open anywhere, forever, without needing the codec at all. A HEIC to PNG option is also available if you need a lossless result.
Method 4: Third-Party Desktop Apps
If you regularly need to batch-convert large folders of HEIC photos offline, a dedicated desktop app can be worth installing. Look for one that's actively maintained and clearly states it processes files locally rather than uploading them. For most people, though, the codec install (Method 1) or a browser-based converter (Method 3) covers the same need with far less setup.
Which Method Should You Pick?
If you regularly receive HEIC files from an iPhone-using friend or family member, install the codec once (Method 1) and forget about it. If this is a one-time situation — someone just sent you a single photo — skip straight to converting it online (Method 3) and you'll have a usable JPG in under a minute.
