What is HEIC and Why Won't It Open?
HEIC stands for High-Efficiency Image Container. Apple introduced it in iOS 11 (2017) as the default photo format for iPhones and iPads. It uses HEVC (also known as H.265) compression — the same technology used in high-efficiency 4K video — to store photos at roughly half the file size of an equivalent JPG.
The problem is that HEVC is a licensed codec technology. While Apple, which owns devices that use HEIC, includes the necessary support by default, other operating systems and software don't include it automatically. That's why HEIC photos look like broken files on many Windows PCs, Android phones, and in many desktop applications.
HEIC vs JPG: A Quick Comparison
Before diving into platform-specific fixes, it helps to understand why HEIC exists at all — and when JPG is the better choice for your workflow.
| Feature | HEIC | JPG |
|---|---|---|
| Typical file size (12 MP photo) | 2–3 MB | 4–6 MB |
| Image quality | Equal or better at smaller size | Good, with mild compression artifacts |
| Windows support | Requires codec install | Native, always works |
| Android support | Limited (some apps only) | Universal |
| Web browser support | Safari only | All browsers |
| Email/social media sharing | Often rejected or shown as icon | Universally accepted |
| Live Photos / Depth data | Supported | Not supported |
| Best for | Storing on Apple devices | Sharing across all platforms |
When Should You Keep HEIC?
HEIC isn't a bad format — it's excellent at what it does. There are genuine situations where keeping your photos as HEIC makes sense:
- You stay entirely within the Apple ecosystem. If you only ever view, edit, and share photos on iPhone, iPad, and Mac, HEIC works transparently and saves significant storage space on your device and iCloud.
- You're archiving originals. HEIC preserves Apple-specific metadata like Live Photo sequences, Portrait mode depth maps, and HDR information. Converting to JPG permanently discards this data.
- Storage is a priority. On a 64 GB iPhone, the difference between shooting HEIC and JPG can add up to hundreds of photos per year — a meaningful practical advantage.
- You use modern editing apps. Applications like Lightroom (version 2.3 and later), Affinity Photo 2, and Apple Photos natively support HEIC. If your workflow stays inside these apps, there's no reason to convert.
The rule of thumb: shoot in HEIC, convert when you share. That's exactly what Converter.Plus is designed for.
Why Can't Windows Open HEIC Files?
Windows 10 and Windows 11 do not include the HEVC codec by default. To open HEIC files in Windows Photos or File Explorer, you need to install the "HEIF Image Extensions" (free) and the "HEVC Video Extensions" (paid, or free if your PC included it) from the Microsoft Store.
If you'd rather not deal with codec installations, the fastest solution is to convert your HEIC files to JPG using our free HEIC to JPG converter. This works in any browser on any version of Windows — no downloads, no store visits, no codec purchases.
Why Can't Photoshop Open HEIC Files?
Adobe added native HEIC support in Photoshop 22.4.3 (part of Creative Cloud 2021). If you're on an older version, Photoshop will be unable to open HEIC files directly. Even with a newer version, support can be inconsistent depending on your operating system's codec setup.
The reliable workaround: convert your HEIC to JPG or PNG first, then open the converted file in Photoshop. The conversion takes seconds and produces a high-quality result.
Why Can't Android Open HEIC Files?
Android's default gallery and file manager apps don't support HEIC. Some third-party apps (like Google Photos) have added HEIC support, but it's not guaranteed. The easiest solution is to open converter.plus/heic-to-jpg in Chrome on your Android device and convert the files directly.
Platform-Specific Troubleshooting
HEIC Files in Google Drive
Google Drive can store HEIC files without issue, but it cannot preview them. When you open a HEIC file in Drive, you'll see a message saying the preview is unavailable. Drive also doesn't convert them automatically — it just shows a download prompt.
To share HEIC photos via Google Drive so recipients can actually view them: convert them to JPG first using Converter.Plus, then upload the JPG files. Recipients will be able to preview and download them directly in Drive without any codec requirements.
HEIC Files in Adobe Lightroom
Adobe Lightroom (version 2.3 for mobile, and Lightroom Classic 9.3 on desktop) added HEIC import support. However, several edge cases can cause problems:
- Lightroom Classic on Windows requires the HEVC codec to be installed on the system — even if Lightroom itself is up to date.
- Older Lightroom versions (pre-2020) have no HEIC support at all.
- Some HEIC files from older iPhone models may import with incorrect color profiles.
If Lightroom is refusing to import your HEIC files, the fastest fix is to batch-convert them to JPG using Converter.Plus, import the JPGs, and work from there. Quality loss is minimal at a high JPG setting.
HEIC Thumbnail Preview in Windows File Explorer
Even after installing the "HEIF Image Extensions" from the Microsoft Store, File Explorer thumbnails for HEIC files may not appear immediately — or ever — on some Windows configurations. This is a known issue caused by how Windows caches thumbnails.
To fix thumbnail previews on Windows:
- Open File Explorer Options from the Control Panel.
- Under the View tab, uncheck "Always show icons, never thumbnails."
- Clear the thumbnail cache: open Disk Cleanup, check "Thumbnails", and click OK.
- Restart File Explorer by pressing Ctrl+Shift+Esc, finding "Windows Explorer" in the Processes tab, and clicking Restart.
If thumbnails still don't appear after following these steps, the fastest workaround remains converting your HEIC files to JPG — File Explorer has supported JPG thumbnails since Windows XP.
The Fastest Fix: Convert HEIC to JPG or PNG
Converting your HEIC photos to JPG or PNG instantly makes them compatible with every device, every application, and every website. Converter.Plus does this entirely in your browser:
- Open converter.plus/heic-to-jpg in any browser.
- Drag your HEIC files onto the page — you can drop multiple files at once.
- Click Convert.
- Download your JPG files. Done.
Your photos never leave your device. All processing happens locally using WebAssembly in your browser.
How to Prevent HEIC on iPhone Going Forward
If you'd rather your iPhone always shoot in JPG instead of HEIC:
- Open the Settings app on your iPhone.
- Tap Camera.
- Tap Formats.
- Select Most Compatible.
From now on, your camera will save photos as JPG. Note that photos already saved as HEIC are not affected by this change. You can also use AirDrop to a non-Apple device — iOS will automatically convert HEIC to JPG during the transfer if the recipient's device doesn't support HEIC.
For most people, the ideal approach is a hybrid: keep your iPhone shooting HEIC to save storage, and convert specific photos to JPG with Converter.Plus whenever you need to share them outside the Apple ecosystem.
