How to Change the Screenshot File Format to JPG on Mac

There are some easy solutions to the PNG format.

Mte Feat Mac Photo

When taking a screenshot on your Mac, you may notice that macOS saves all screenshots in the PNG (Portable Network Graphics) format by default. While this lossless format can retain the quality of an image, the files tend to be larger than the other formats (like .jpg), which causes longer loading times. Luckily, there’s a little trick that lets you change the screenshot file format on your Mac to .jpg.

The trick requires the use of Terminal, which issues a command that tells the Mac to change the screenshot file format to .jpg. This tutorial walks you through the process.

Changing the Screenshot File Format on a Mac

Launch Terminal on your Mac by opening Spotlight and searching for and clicking on “Terminal.”

The most common photo file type is JPEG, also known as JPG. To change the default screenshot format from PNG to JPG, type the following command into Terminal and press Enter:

defaults write com.apple.screencapture type jpg;killall SystemUIServer
Mac Terminal To Jpg

Try capturing a screenshot using the Command + Shift + 3 combo. You should see the screenshot saved in the JPG format instead of PNG.

Changing the Screenshot Format to GIF

GIF images are usually low-quality images that do not retain the full quality of the image that was captured. It’s a good option if the little details of the image aren’t important.

defaults write com.apple.screencapture type gif;killall SystemUIServer

Changing the Screenshot Format to TIFF

TIFF stands for Tagged Image File Format. It’s a format usually saved for high-quality images. To make your screenshots use this format, use the following command:

defaults write com.apple.screencapture type tiff;killall SystemUIServer

Changing the Screenshot Format to PDF

PDF is usually used for documents. You can have your screenshots saved to this format using the below command:

defaults write com.apple.screencapture type PDF;killall SystemUIServer

Reverting to the Original Screenshot File Format

If you tried all of the above file formats but nothing seemed to work as great as the default PNG format, you can revert back to PNG as the default by running the following command in Terminal, just as explained above.

defaults write com.apple.screencapture type png;killall SystemUIServer

Frequently Asked Questions

Is there a way to configure screenshot file formats without using Terminal?

Unfortunately, no. You can do many things with the built-in Screenshot app on your Mac but cannot configure file formats before you shoot unless you use the Terminal app.

How can I reduce the file size of my screenshots without impacting quality?

You may want to share several JPG screenshots over email or another service. To reduce the file size of one or multiple screenshots, compress the JPG files by selecting them followed by a two-finger click or right click. From the drop-down menu that appears, select “Compress.”

If I want a transparent background for my screenshot, which file format should I use?

macOS captures screenshots in PNG format by default. PNG files not only offer higher quality but also feature transparent backgrounds, making them ideal for use with image-editing software or inside presentations.
