Frequently Asked Questions

You've just received iPhone photos, downloaded them from iCloud, or transferred them via USB — and now none of them open. The files end in .heic and every app says it can't display them. This is one of the most frustrating compatibility problems that iPhone users encounter.

The good news: it's fixable in under two minutes. Here's a systematic guide to diagnosing and resolving every HEIC opening failure.

Common Error Messages and What They Mean

"Windows can't open this file" / "We can't open this type of file"

Cause: Windows has no application associated with .heic files. Fix: Install the HEIC to JPG Converter Chrome extension to convert the files, or install the HEIF Image Extensions codec from the Microsoft Store.

"This file can't be displayed" in Windows Photos

Cause: Windows Photos recognizes HEIC files but lacks the HEVC codec to decode them. Fix: Install "HEIF Image Extensions" from the Microsoft Store (free) or "HEVC Video Extensions" ($0.99) for full compatibility.

HEIC files show as generic icons with no preview in File Explorer

Cause: Missing HEIC codec prevents Windows from generating thumbnails. Fix: Install the HEIF Image Extensions codec from the Microsoft Store, then restart Windows Explorer via Task Manager.

HEIC uploads fail or show as broken images on websites

Cause: Most websites don't support HEIC uploads. They expect JPG or PNG. Fix: Convert HEIC to JPG before uploading to any website or online service.

HEIC file opens as garbled or black image

Cause: The application is attempting to open the HEIC file using an incompatible decoder, producing corrupted output. Fix: Use a dedicated HEIC viewer or convert to JPG first.

Fix 1: Chrome Extension (No Downloads Required)

This is the fastest fix for Windows users. The HEIC to JPG Converter Chrome extension converts HEIC to JPG locally in your browser, producing standard JPG files that open in any app.

Install the extension Go to the HEIC to JPG Converter Chrome Web Store page and click "Add to Chrome".
Open Chrome and load your HEIC file Press Ctrl+O and select your HEIC file, or drag it into a Chrome tab.
Click the extension icon and convert Click the HEIC Convert icon in your toolbar, select your quality/format preferences, and click Convert.
Download and open the JPG Your converted JPG downloads to your Downloads folder. Double-click to open it in any viewer on Windows.

Fix 2: Install the HEIF Codec (Windows)

This fix enables Windows to open HEIC files natively in Photos, File Explorer thumbnails, and compatible apps.

Open the Microsoft Store Press the Windows key, type "Microsoft Store", and open it.
Search "HEIF Image Extensions" Type in the search bar. Look for the app published by Microsoft Corporation.
Install the free version Click "Get" to install. This takes 1–2 minutes.
Optionally add HEVC Video Extensions For full HEIC compatibility, also install "HEVC Video Extensions" ($0.99) — this handles certain HEIC variants that the free HEIF codec doesn't decode correctly.
Restart Windows Explorer Open Task Manager (Ctrl+Shift+Esc), find "Windows Explorer" in the list, right-click it, and select Restart. This refreshes thumbnails in File Explorer.

After the Codec Fix: HEIC files will show thumbnails in File Explorer, open in Windows Photos by double-clicking, and display correctly in apps that use Windows imaging APIs. However, you'll still need to convert HEIC to JPG for web uploads and apps that don't use the Windows codec.

Fix 3: macOS HEIC Not Opening

On Mac, HEIC files should open natively in Preview on macOS 10.13 High Sierra and later. If they don't:

Check your macOS version: Older versions (before 10.13) don't support HEIC. Update macOS if possible.
Right-click → Open With → Preview: Sometimes the file association gets broken. Right-click your HEIC file and manually choose Preview as the app.
Reset file associations: In Finder, right-click a HEIC file → Get Info → Open With → change to Preview → click "Change All"
Convert to JPG: If Preview still fails, use the Chrome extension to convert the file to JPG first.

Fix 4: HEIC Not Opening in Specific Apps

Photoshop

Photoshop on Windows requires Camera Raw 9.9+ to open HEIC files. Update Photoshop through Creative Cloud, or use the Chrome extension to convert HEIC to JPG/TIFF first.

GIMP

GIMP doesn't support HEIC by default. Install the HEIF/HEIC plugin from GIMP's plugin registry, or convert to JPG/PNG first.

Paint.NET

Paint.NET supports HEIC only with the HeicFileType plugin from the plugin repository. Alternatively, convert to JPG first.

Microsoft Office apps

Word, PowerPoint, and Excel can insert HEIC images if the HEIF Image Extensions codec is installed. Without the codec, you'll see a "can't insert this image" error.

Fix 5: HEIC Not Opening on Android

Android HEIC support is fragmented. On Android 12+, some devices can open HEIC natively, but app support varies. The most reliable approach:

Convert HEIC to JPG on your computer before transferring to Android
Use Google Photos, which can display HEIC files uploaded from iCloud
On iPhone, change Settings → Camera → Formats → Most Compatible to send JPG via USB

Fix 6: HEIC Email Attachments Not Opening

If you received a HEIC file via email and can't open it:

Save the HEIC file to your desktop Right-click the email attachment and save it to a known location.
Convert using the Chrome extension Drag the saved HEIC file into Chrome and use the HEIC to JPG Converter extension.
Open the converted JPG normally The JPG file opens in any image viewer.

Never Struggle With HEIC Files Again

Install the HEIC to JPG Converter once and convert any HEIC file in seconds, right in Chrome.

Frequently Asked Questions

Why won't my HEIC files open?

HEIC files won't open when the software on your device lacks the HEVC codec required to decode them. This is most common on Windows (which doesn't include the codec by default), Chrome/Firefox browsers, and older Android devices. The solution is either to install the HEIC codec or convert the files to JPG using a converter like the HEIC to JPG Converter Chrome extension.

How do I open HEIC files on Windows without the Microsoft Store?

Install the HEIC to JPG Converter Chrome extension. It converts HEIC files to JPG locally in your browser without requiring any Microsoft Store downloads or codec installations. The converted JPG files open in any application on Windows.

Why does Windows say "This file can't be displayed" for HEIC files?

This error means Windows doesn't have the HEIC codec installed. You need either the HEIF Image Extensions from the Microsoft Store, or a dedicated HEIC converter to change the files to a supported format like JPG.

HEIC files show as blank thumbnails in File Explorer — how do I fix this?

Blank HEIC thumbnails in File Explorer indicate a missing HEIC codec. Install the HEIF Image Extensions from the Microsoft Store to enable thumbnail previews. After installation, restart Windows Explorer (via Task Manager) to refresh thumbnails.

Can I open HEIC files on Android?

HEIC support on Android varies by device and manufacturer. Android 12+ has basic HEIC support, but not all apps handle it correctly. The most reliable approach is to convert HEIC to JPG before transferring to Android devices.
