How to convert JPEG to JPG on Mac

Although JPEG and JPG are often used interchangeably, there are situations where you may need to convert JPEG to JPG on Mac. Perhaps you're trying to upload an image to a website that only accepts JPG files, or maybe you just prefer the JPG format.

Regardless of the reason, converting JPEG to JPG on a Mac can be a straightforward process. In this post, we'll guide you through the steps to change JPEG to JPG on Mac. Before diving into details, it's important to understand the difference between the two formats.

How to convert JPEG to JPG on Mac?

The maximum 3-letter limit for file extension was never applied to Unix systems, so Mac operating systems continued using the .jpeg extension to save images. That's why you may need a bit of tweak to change images to .jpg on Mac. Typically, there are three ways to convert JPEG files to JPG files on Mac.

Way 1: Convert JPEG to JPG on Mac using iBoysoft MagicMenu

The easiest and most efficient way to convert from JPEG to JPG on Mac is by using iBoysoft MagicMenu. It's a Finder context menu extension utility that allows you to convert image files to different formats, including JPEG to JPG. With it, you can right-click to batch convert JPEG images to JPG on Mac, without the need to launch an app or upload and download files.

Here's how to batch convert JPEG to JPG on Mac:

Step 1: Download and install the JPEG to JPG converter for free.

Step 2: Select the JPEG images you want to change to JPG formats, then right-click on them and select "ImageConvert."

A window will open with all your JPEG images selected.

Step 3: Check the box next to "Convert all file types to" and select "JPG."

If you notice the "Original file type" column lists your JPEG files as jpg, don't be surprised. As we mentioned earlier, .jpeg and .jpg are two extensions for the same format.

Step 4: Choose whether to save the converted JPG files to the original folder.

If you'd like to store the JPG images in a different folder, check the box next to "Custom" and select the desired location. If you choose to keep using the original folder, the converted files will have an extra word (1) added to their name to avoid conflicts with the original JPEG images.

Step 5: Click "Start converting."

The speed of the conversion depends on the number and size of files being processed. After the images are converted successfully, you can check them in the directory you chose to save them. It's worth mentioning that both .jpg and .jpeg extensions are categorized as JPEG images on Mac.

Way 2: Change JPEG to JPG on Mac by renaming the extension

Another way to change JPEG to JPG on Mac is by renaming the extension. It's different from converting images, as the extension name is the only thing being modified. Therefore, it won't affect the file size or image quality of the JPEG files. However, this method may not work for some sites that require .jpg files. If this is the case, try iBoysoft MagicMenu instead.

  1. Right-click on the JPEG file and select Rename.

JPEG vs. JPG: Are they the same?

JPEG, which stands for Joint Photographic Experts Group, is a widely used format for storing and sharing digital images. Meanwhile, JPG is a shortened version of JPEG that only exists because earlier versions of Windows operating systems (MS-DOS 8.3 and FAT-16) don't support extensions with more than 3 letters.

Therefore, JPEG and JPG are essentially the same file formats with the only difference being the number of characters used in the file extension. Still, some applications or websites may only accept files with the JPG extension.


Will converting JPEG to JPG on Mac reduce the image quality?

Generally speaking, converting from JPEG to JPG won't reduce the image quality, as they are fundamentally identical formats. But sometimes, you may notice that the converted JPG file has a larger file size. One likely reason for the file size increase is that your image converter uses a different color profile.

To verify this, right-click on both the original JPEG image and the converted JPG image and select "Get Info" to compare their color profiles.

A color profile is used to ensure that colors in an image appear consistent and accurate on different devices. The default color profile for Mac displays is color LCD, which is ideal for general use such as web browsing, document editing, email, etc.

However, the color profile used by most digital images is sRGB IEC61966-2.1 because it's compatible for most devices and applications. Your image converter may use the more popular sRGB as color profile when converting from JPEG to JPG and cause the file size to be larger.

Tips for saving screenshots to JPG on a Mac

If you prefer using the .jpg extension on Mac, here's a simple tip to change the default screenshot formats to JPG on Mac. 

  1. Open Finder, then launch Terminal from the Applications/Utilities folder.
  2. Copy and paste the following command into Terminal and press Enter.defaults write com.apple.screencapture type JPG;killall SystemUIServerRun Terminal commands to change default screenshot format to jpg on Mac 

From now on, every screenshot you take will automatically be saved as a JPG file.
