How to View HEIC Photos on Mac

HEIC (High Efficiency Image Coding) is Apple’s default photo format on iPhone and iPad. It saves space while keeping quality, but some Mac apps and older systems can’t read it. This guide shows you how to view HEIC photos on a Mac using built-in tools and free workarounds, with no extra software needed for most cases.

What You’ll Need

A Mac running macOS High Sierra (10.13) or later – HEIC support is built-in from this version onward.
The HEIC file itself (if it came from an iPhone, it’s usually in the Photos app or in a folder like Downloads).
Optional: an internet connection if you want to use a free online converter for older Macs.

Step-by-Step

Double-click the HEIC file. On a Mac with macOS High Sierra or newer, Preview opens HEIC files automatically. Just double-click the file in Finder. If it opens, you’re done – you can view, zoom, and even edit it in Preview.
If double-click doesn’t work, open it in Preview manually. Right-click the file, choose Open With, then select Preview. If Preview isn’t listed, click Other and navigate to /Applications/Preview.app.
Use the Photos app for iPhone imports. If your HEIC photos are in the Photos library, open the Photos app. They’ll display normally because Photos converts them for viewing. If you see a placeholder or a “not supported” message, the file might be corrupted or from an older source.
Check if Quick Look works. Select the HEIC file in Finder and press the spacebar. Quick Look should show a preview without opening any app. If it shows a blank or an error, your Mac’s system version is likely too old.
For older Macs (pre-High Sierra), convert the file. Use a free online converter like CloudConvert or Zamzar. Upload the HEIC file, choose JPG or PNG as the output, and download the converted image. Then you can view it with any image viewer.
If you have a lot of HEIC files, convert them in bulk. In Preview, open all the HEIC files (select them in Finder, then drag them onto the Preview icon in the Dock). Then go to File > Export, choose JPEG, and save them all to a folder. This works on macOS 10.13 and later.

Common Mistakes

Assuming all Macs support HEIC. Only macOS 10.13 (High Sierra) and later have native HEIC support. If you’re on an older system, double-clicking won’t work.
Using the wrong app. Some third-party image viewers, like older versions of Photoshop or GIMP, don’t support HEIC. Always try Preview first.
Confusing HEIC with HEIF. HEIC is the file extension for HEIF images. They’re the same format, but some tools might label them differently. The steps here work for both.
Forgetting to check the file extension. If a file is named .heic but is actually a different format (e.g., renamed from .jpg), Preview might fail. Right-click the file, select Get Info, and check the “Kind” field.

Tips

Set your iPhone to capture JPEG instead of HEIC if you regularly share photos with non-Apple devices. Go to Settings > Camera > Formats and select “Most Compatible.”
Use the “Automatic” setting in Photos for Mac. When you import from an iPhone, Photos can automatically convert HEIC to JPEG for sharing. Go to Photos > Settings > General and check “Transfer to Mac or PC” as Automatic.
Install the HEIC codec for Windows if you also use a PC. Microsoft offers a free HEIF extension from the Store. This doesn’t affect your Mac, but it makes sharing easier.
Keep your Mac updated. Newer macOS versions improve HEIC handling and performance. Check for updates in System Settings > General > Software Update.
Use Preview’s editing tools. You can crop, adjust color, and even remove background from HEIC files directly in Preview – no conversion needed.

Troubleshooting

HEIC file won’t open in Preview. First, verify your macOS version (Apple menu > About This Mac). If it’s High Sierra or later, try copying the file to your Desktop and reopening. If that fails, the file might be corrupted – try downloading it again from iCloud or your camera.

Preview opens but shows a black or blank screen. This can happen with very large HEIC files. Try opening the file in Photos instead. If that works, the file is fine; Preview might be struggling with the resolution. Use Photos to export a smaller version.

Quick Look shows “No Preview Available.” This usually means the file isn’t a valid HEIC. Check the file extension – if it’s .heic but came from a non-Apple source, it might be mislabeled. Try renaming the file to .heif and opening again.

Photos app says “Unsupported Format.” This is rare on macOS 10.13+, but if it happens, the file might have been saved with an incompatible HEIC variant (e.g., from a third-party camera). Convert it online to JPEG and then import.

You’re on an older Mac and can’t update. If your Mac doesn’t support High Sierra (e.g., a 2009 model), you can’t view HEIC natively. Use a free online converter every time, or install a third-party app like “HEIC Viewer” from the Mac App Store (check compatibility).

HEIC files are huge and slow to open. This is normal – HEIC is efficient but decoding takes more CPU. Close other apps and try again. If it’s consistently slow, convert the files to JPEG for everyday viewing.

Frequently Asked Questions

Q: Can I view HEIC photos on macOS Sierra (10.12) or earlier?
A: No, native HEIC support started in High Sierra (10.13). On older versions, you must convert the files to JPEG or PNG using an online converter or a third-party app.

Q: Why did my iPhone save photos as HEIC instead of JPEG?
A: To save storage space. HEIC is about half the size of JPEG at the same quality. You can change this in iPhone Settings > Camera > Formats to “Most Compatible” for JPEG.

Q: Does converting HEIC to JPEG lose quality?
A: Yes, JPEG is a lossy format, so converting from HEIC to JPEG will reduce quality slightly. However, if the HEIC was captured at high quality, the difference is usually imperceptible.

Q: Can I edit HEIC files in Preview?
A: Yes, Preview supports editing HEIC files just like JPEG – you can crop, adjust exposure, and more. Changes are saved back to the HEIC file.

Q: How do I send HEIC photos to a Windows user?
A: The easiest way is to convert them to JPEG first (in Preview, File > Export, choose JPEG). You can also share via iCloud link, which lets the recipient view them in a browser without conversion.

Q: Are HEIC files safe to delete after converting?
A: Yes, once you have JPEG copies, you can delete the originals to save space. But keep in mind that HEIC retains more detail, so if you plan to edit heavily later, keep the originals.
