The fastest way to convert HEIC to JPG on Mac

The simplest method is to open the HEIC file in Preview (the built-in image viewer on every Mac), then export it as JPG. Preview comes with macOS and requires no download or setup. Open the HEIC photo, click File, then Export, choose JPEG from the format dropdown, and save. This takes about 30 seconds per photo.

If you have many photos to convert at once, the Finder's Quick Actions tool can batch-convert them without opening each file individually. Right-click a folder of HEIC files, select Quick Actions, then Convert Image. You can set the format to JPEG and the quality level before converting the entire folder.

For photographers or designers who convert images regularly, third-party apps like ImageMagick (free, command-line based) or Permute 3 (paid, with a graphical interface) offer more control over compression and color settings. These are optional — Preview handles the conversion well for most people.

Key Takeaways

  • Preview, which comes free with macOS, can convert a single HEIC file to JPG in under a minute through File > Export.
  • Finder's Quick Actions tool converts multiple HEIC files to JPEG at once without opening each one separately.
  • HEIC files are smaller than JPG but not all devices and websites accept them, which is why conversion is often necessary.
  • Third-party apps like ImageMagick or Permute 3 give you more control over quality and compression if you convert images frequently.

Converting one photo at a time in Preview

Open Finder and locate your HEIC photo. Double-click it to open it in Preview (the default image viewer). At the top of the window, click File, then look for Export in the dropdown menu. A dialog box will appear asking where to save the file and what format to use.

In the format dropdown, select JPEG. You will see a slider for image quality — the default setting (around 75%) is fine for most uses. Higher quality means a larger file; lower quality means smaller but grainier. Click Save, and Preview creates a new JPG file in the location you chose. The original HEIC file stays unchanged.

This method works for one or two photos. If you have dozens, the batch method below is faster.

Converting multiple photos at once with Quick Actions

Open Finder and navigate to the folder containing your HEIC files. Select all the photos you want to convert (Command+A selects everything in the folder). Right-click the selected files and look for Quick Actions in the menu that appears.

Click Quick Actions, then Convert Image. A small window will pop up with options: choose JPEG from the format dropdown and set the quality level. Click Convert, then choose where to save the new JPG files. Finder will convert all selected photos and save them in that location, leaving the originals untouched.

This approach saves time if you have 10 or more photos. For smaller batches, Preview is often faster because you skip the setup steps.

Using command-line tools for advanced control

If you are comfortable with Terminal, ImageMagick is a free tool that converts images with precise control over quality, compression, and color profiles. Install it through Homebrew (a package manager for Mac) by opening Terminal and typing the installation command. Once installed, you can convert a single file with a one-line command or write a script to batch-convert hundreds of photos.

ImageMagick is powerful but has a learning curve. Most people do not need it — Preview and Quick Actions handle everyday conversions. Consider ImageMagick only if you convert images as part of your work and need settings that Preview does not offer.

When to use third-party apps like Permute 3

Permute 3 is a paid app (around $30) that provides a graphical interface for converting images, audio, and video. It shows a preview of your image before conversion and lets you adjust quality, resize, and apply filters without touching the command line. If you convert images weekly or more often, the time saved might justify the cost.

Most casual users never need Permute 3. Preview and Quick Actions are free and built into macOS, so start there. Move to a third-party app only if you find yourself converting images so often that the extra features become worth the money.

Why HEIC files exist and when JPG is better

HEIC (High Efficiency Image Container) is Apple's newer image format. It produces smaller files than JPG while keeping the same visual quality, which saves storage space on your iPhone and Mac. However, many older devices, websites, and software do not recognize HEIC files. If you need to upload a photo to a website, email it to someone with an older device, or use it in software that does not support HEIC, converting to JPG solves the problem.

JPG is older and more widely supported. Nearly every device, website, and program accepts JPG files. The trade-off is that JPG files are larger than HEIC for the same image quality. If storage space is not a concern and everyone you share with can open HEIC files, there is no reason to convert.

Checking file format and avoiding mistakes

Before converting, confirm the file is actually HEIC. Right-click the photo, select Get Info, and look at the Kind field. It will say "HEIC Image" or "HEIF Image" if it is the format you think. Some photos that look like they might be HEIC are already JPG, especially if they came from an older camera or Android device.

After conversion, you will have both the original HEIC file and the new JPG file. If you no longer need the HEIC version, you can delete it to save space. If you want to keep only JPG files, delete the HEIC after confirming the JPG looks correct on the device or website where you plan to use it.

Frequently Asked Questions

Does converting HEIC to JPG reduce image quality?

Not noticeably. HEIC and JPG are both compressed formats, and the quality loss from conversion is minimal if you use the default or high-quality setting in Preview. The JPG file will be slightly larger than the original HEIC, but the image will look the same to the human eye.

Can I convert HEIC to JPG on an older Mac?

Yes, as long as your Mac runs macOS 10.13 or later, Preview can open and export HEIC files. If your Mac is older than that, you can use free online converters or install ImageMagick through Terminal. Check your macOS version in the Apple menu under About This Mac.

What if Quick Actions does not show the Convert Image option?

Quick Actions may not appear if you are using an older version of macOS. Update to the latest macOS version through System Preferences > Software Update. If updating does not help, use Preview to convert files one at a time, or try a free online HEIC-to-JPG converter.

Is it safe to use online HEIC converters?

Online converters work, but they upload your photo to someone else's server. If the photo contains personal information or you prefer to keep it private, use Preview or Quick Actions instead — both work entirely on your Mac without uploading anything.

Can I convert JPG back to HEIC?

Yes, Preview can export to HEIC format the same way it exports to JPG. Open the JPG file in Preview, click File > Export, choose HEIC from the format dropdown, and save. The HEIC version will be smaller than the JPG, but you cannot recover any detail that was lost when the photo was originally converted to JPG.
