How to Change HEIC to JPG on Mac: Every Method Explained

Apple's HEIC format is efficient and modern — but the moment you try to share a photo with someone outside the Apple ecosystem, or upload it to a platform that doesn't recognize it, the format becomes a friction point. Fortunately, macOS gives you several ways to convert HEIC files to JPG, ranging from built-in tools that require no downloads to third-party options built for bulk workflows.

Here's how each method works, what it's good for, and what to consider before choosing one.

What Is HEIC and Why Does It Need Converting?

HEIC (High Efficiency Image Container) is the default photo format on iPhones running iOS 11 and later. It compresses images more efficiently than JPG — meaning smaller file sizes at comparable quality — but it relies on codec support that Windows, many web platforms, and older software simply don't have.

JPG (or JPEG) remains the universal standard for photos. It's supported everywhere: browsers, social platforms, Windows PCs, Android devices, design tools, and legacy software. When compatibility matters more than compression efficiency, JPG wins.

Method 1: Convert Using Preview (Built-In, No Downloads)

Preview is macOS's native image viewer and it handles HEIC conversion natively on macOS High Sierra and later.

To convert a single file:

1. Open the HEIC file in Preview
2. Go to File → Export
3. In the Format dropdown, select JPEG
4. Adjust quality using the slider if needed
5. Choose a save location and click Save

To convert multiple files at once:

1. Select all the HEIC files in Finder
2. Right-click and choose Open With → Preview
3. In Preview, press ⌘A to select all images in the sidebar
4. Go to File → Export Selected Images
5. Choose a destination folder — Preview will export all files as JPG if you set the format accordingly

⚠️ One detail: when batch exporting, the format option appears in the export dialog. Make sure JPEG is selected, not the default format.

Preview works well for occasional conversions and small batches. It doesn't require any setup and produces clean output with adjustable compression.

Method 2: Convert Using Photos App

If your HEIC images are already in your Photos library, you can export them as JPG directly from the app.

1. Open Photos and select the images you want to convert
2. Go to File → Export → Export [X] Photos
3. In the export window, set Photo Kind to JPEG
4. Choose your JPEG quality and filename options
5. Click Export and select a destination

This method is straightforward for images already managed in Photos. It also lets you export with or without metadata, which matters depending on whether you want location data and timestamps preserved.

Method 3: Use Automator for Large Batches 🔄

For workflows where you regularly need to convert large numbers of HEIC files, Automator — macOS's built-in automation tool — can handle this without any third-party software.

Basic setup:

1. Open Automator (found in Applications or via Spotlight)
2. Create a new Quick Action or Application
3. Add the action Change Type of Images (search for it in the action library)
4. Set the output type to JPEG
5. Optionally add a Copy Finder Items action first to avoid overwriting originals
6. Save and run your workflow on a folder of HEIC files

Automator workflows can be saved and reused, making this the most efficient option if conversion is part of a recurring process. The learning curve is low for basic workflows, though more complex setups require some familiarity with Automator's logic.

Method 4: Third-Party Converters and Apps

Several third-party tools exist specifically for HEIC-to-JPG conversion. These range from Mac App Store applications to command-line utilities to browser-based converters.

Browser-based converters are convenient but involve uploading your photos to a third-party server. For personal or sensitive images, that's worth factoring in.

ImageMagick is a powerful command-line option available via Homebrew. A basic conversion command looks like:

magick input.heic output.jpg 

This approach suits users comfortable with Terminal and offers fine-grained control over compression, color profiles, and batch processing via shell scripts.

Factors That Affect Which Method Works Best for You 🖥️

The right approach isn't the same for everyone. A few variables shape the decision meaningfully:

• Volume: Converting 3 photos occasionally is very different from processing 500 images from a photoshoot
• macOS version: Preview's HEIC support requires macOS High Sierra (10.13) or later; older systems may need third-party tools
• Preservation of metadata: Some methods strip EXIF data (GPS, timestamps, camera settings) by default; others preserve it
• Original file handling: Some tools convert in place; others export copies — important if you want to keep originals untouched
• Workflow integration: If conversion is part of a larger editing or backup process, Automator or command-line tools integrate more cleanly than manual GUI methods
• Privacy sensitivity: Images containing location data or private content should probably stay off browser-based tools

A Note on Changing Default Capture Format

If you want to prevent the conversion need altogether, iPhones can be set to capture in JPG directly. Under Settings → Camera → Formats, selecting Most Compatible shoots in JPG instead of HEIC. Whether that trade-off — larger file sizes in exchange for universal compatibility — makes sense depends entirely on your storage situation and how often you share photos cross-platform.

The conversion methods above handle the files you already have. But for some users, adjusting capture settings removes the friction at the source rather than downstream.

How much any of this matters — and which approach fits — comes down to how you actually work with your photos, what software is part of your workflow, and how often you're dealing with compatibility issues in the first place.
