How to Convert HEIC to JPG on Mac? How to Change Image Format?

This guide explains how to easily convert HEIC images to JPG format on your Mac, addressing compatibility issues with other devices and platforms. While HEIC offers superior compression and quality, its limited compatibility necessitates conversion for wider sharing.

HEIC Explained:

HEIC (High-Efficiency Image Container) is a more efficient image format than JPG, resulting in smaller file sizes without sacrificing image quality. Introduced with iOS 9, it's now standard across many Apple devices and macOS versions from High Sierra onwards.

When to Convert HEIC to JPG:

Convert HEIC to JPG when sharing images outside the Apple ecosystem. This includes social media platforms like Facebook and Instagram, as well as sharing with users of Android or Windows devices, or older iOS devices (pre-iOS 9).

Converting HEIC to JPG using Preview:

The simplest method uses macOS's built-in Preview app:

1. Open your HEIC file in Preview.
2. Go to File > Export.
3. Select JPEG as the format and adjust the Quality slider.
4. Choose a file name and location, then click Save.

Automatic HEIC to JPG Conversion:

For batch conversion, consider these automated options:

1. Photos App: Import HEIC images into Photos. Dragging them to a Finder window automatically converts them to JPG. Alternatively, use File > Export > Export Photos for more control over format, naming, and location.

2. Automator: (Instructions for Automator are omitted for brevity, but this is another powerful batch processing option within macOS.)

Third-Party Apps (for older macOS versions):

Older macOS versions might require third-party HEIC to JPG converters. Exercise caution when using online converters due to potential security risks and privacy concerns.

Batch Conversion using Finder and Preview:

For bulk conversion:

1. Select all HEIC files in Finder.
2. Right-click and choose Open With > Preview.
3. In Preview, select Edit > Select All.
4. Go to File > Export Selected Images.
5. Choose JPEG and adjust quality settings.

Saving Photos as JPG Directly:

To avoid conversion altogether, change your iPhone's camera settings:

1. Go to Settings > Camera > Formats.
2. Select Most Compatible to save images as JPG.

Conclusion:

While HEIC offers benefits, converting to JPG remains essential for broader compatibility. This guide provides multiple methods to achieve this efficiently, catering to different user needs and macOS versions. Remember to consider the security implications when using third-party tools.
