How to Convert Images to HEIC on Mac

What you need

• macOS 14.0 or later
• PixPack – Image Compressor Pro from the Mac App Store
• Source images in JPEG, PNG, WebP, GIF, BMP, TIFF or HEIC

Step by step

1. Add the images

   Add the files or drag in the folder you want to convert.

2. Set the output format to HEIC

   Choose HEIC from the format options.

3. Choose quality and dimensions

   Select a preset such as Archive, or set the quality and maximum width and height manually.

4. Decide about metadata

   Keep EXIF data if you need capture information, or strip GPS info if the images will be shared.

5. Preview

   Check the before-and-after preview and the reported savings.

6. Export

   Apply the settings to the batch and export the HEIC files to your output folder.

Why convert to HEIC

HEIC generally stores images more compactly than JPEG at a comparable visual quality. For a large photo library on an Apple device, converting to HEIC can meaningfully reduce storage use while keeping the images readable in Apple apps.

Compatibility considerations

• HEIC opens natively on macOS, iOS and iPadOS
• Windows and older applications may need additional codecs
• Web browsers have limited HEIC support — do not use it for web assets
• If you need maximum compatibility, export JPEG instead

Reversible or not?

Converting to HEIC is a re-encode. Keep your original JPEG or PNG files if they are the highest-quality copies you have, and treat the HEIC output as a space-saving derivative.

Expected result

HEIC copies of your source images at the quality and dimensions you selected, with the size reduction reported per file.

Tips

• Export into a separate folder so the originals remain available.
• Do not use HEIC for web assets — browser support is limited.
• Combine HEIC output with a maximum width for the largest total saving.
