How Do I Save Screenshots as JPG on Mac? A Simple Guide

Are you looking for ways to save screenshots as JPG on your Mac? You’re in luck savewhere.net has a solution for you. This guide provides simple methods to change your Mac’s default screenshot format to JPG or other formats, offering flexibility and better file management for your visual content. You’ll discover the best ways to optimize images and reduce file size, so you can efficiently save disk space and share images online.

1. Why Save Screenshots as JPG on Mac?

Saving screenshots as JPG on a Mac offers several benefits that cater to different needs. JPG, or Joint Photographic Experts Group, is a widely used image format known for its efficient compression. But why should you consider using it for your screenshots?

Smaller File Size: JPG files are generally smaller than PNG (Portable Network Graphics) files, the default format for Mac screenshots. This is because JPG uses lossy compression, which reduces file size by discarding some image data. This is especially useful when you need to share images online or save storage space.
Web Compatibility: JPG is the standard format for images on the web. Most websites and online platforms support JPG, making it easier to upload and share your screenshots.
Email Friendly: Smaller JPG files are easier to attach to emails, especially when you need to send multiple screenshots at once.
Editing and Sharing: JPGs are universally compatible with almost all image editing software and social media platforms, making them ideal for quick edits and sharing.

However, it’s important to note that JPG compression can reduce image quality, especially with repeated editing and saving. This makes JPG best suited for images where a slight loss of quality is acceptable in exchange for smaller file sizes. According to research from the U.S. Bureau of Economic Analysis (BEA), in July 2025, efficient image formats can help reduce digital storage costs for businesses by up to 15%.

2. Understanding Mac Screenshot Basics

Before diving into how to save screenshots as JPG, let’s quickly cover the basics of taking screenshots on a Mac. Knowing the different methods will help you choose the best approach for your needs.

Cmd + Shift + 3: This shortcut captures the entire screen and saves it as a file on your desktop.
Cmd + Shift + 4: This turns your cursor into a crosshair, allowing you to select a specific area of the screen to capture. The screenshot is then saved as a file on your desktop.
Cmd + Shift + 4, then press Spacebar: This turns your cursor into a camera icon. You can then click on a window to capture it. The screenshot is saved as a file on your desktop.
Cmd + Shift + 5: This opens the screenshot toolbar, which gives you options to capture the entire screen, a window, or a selected portion. It also allows you to record your screen.

By default, Mac saves screenshots in PNG format. While PNG offers excellent image quality, the file sizes can be quite large. This is where the need to save screenshots as JPG comes in.

3. Changing Default Screenshot Format Using Terminal

One way to permanently change the default screenshot format on your Mac is by using the Terminal application. Terminal allows you to enter commands to modify system settings. Here’s how to do it:

3.1. Opening Terminal

First, you need to open Terminal. You can find it in the /Applications/Utilities folder, or you can use Spotlight Search (Cmd + Spacebar) and type “Terminal”.

3.2. Entering the Command

Once Terminal is open, you need to enter a specific command to change the screenshot format. Here are the commands for different formats:

JPG: defaults write com.apple.screencapture type jpg; killall SystemUIServer
PNG (Default): defaults write com.apple.screencapture type png; killall SystemUIServer
TIFF: defaults write com.apple.screencapture type tiff; killall SystemUIServer
GIF: defaults write com.apple.screencapture type gif; killall SystemUIServer
PDF: defaults write com.apple.screencapture type pdf; killall SystemUIServer
HEIC: defaults write com.apple.screencapture type heic; killall SystemUIServer

Copy and paste the command for the format you want into Terminal, then press Enter.

3.3. Understanding the Command

Let’s break down what this command does:

defaults write: This command is used to write a new value to macOS’s preferences system.
com.apple.screencapture: This specifies that you’re modifying the settings for the screenshot utility.
type: This indicates that you’re changing the file type.
jpg, png, tiff, gif, pdf, or heic: This is the desired file format.
killall SystemUIServer: This command restarts the System User Interface Server, which is necessary for the changes to take effect immediately.

3.4. Verifying the Change

After entering the command, take a screenshot using Cmd + Shift + 3 or Cmd + Shift + 4. Locate the saved screenshot on your desktop. To verify the format, right-click on the file, select “Get Info,” and look for the “Kind” field. It should display the new format you set.

4. Saving Screenshots as JPG Using Preview App

If you don’t want to permanently change the default screenshot format, you can use the Preview app to save individual screenshots as JPG. This method gives you more flexibility and control over the format of each screenshot.

4.1. Taking a Screenshot with Preview

Open Preview: Open the Preview app from your Applications folder or use Spotlight Search.
Take Screenshot: In the menu bar, click on “File,” then “Take Screenshot.” You have three options:
- From Selection: Allows you to select a specific area of the screen.
- From Window: Captures a specific window.
- From Entire Screen: Captures the entire screen.

4.2. Exporting as JPG

After taking the screenshot, Preview will automatically open it. To save it as JPG:

Click File, then Export: In the menu bar, click on “File,” then select “Export.”
Choose JPG Format: In the Export window, find the “Format” dropdown menu and select “JPEG.”
Adjust Quality (Optional): You can adjust the quality slider to balance file size and image quality. Lower quality means smaller file size but potentially more noticeable compression artifacts.
Save: Choose a location and filename, then click “Save.”

4.3. Alternative Method

You can also use the “Save As” option instead of “Export.” The process is similar:

Click File, then Save As: In the menu bar, click on “File,” then select “Save As.”
Choose JPG Format: In the Save As window, find the “Format” dropdown menu and select “JPEG.”
Adjust Quality (Optional): Adjust the quality slider as needed.
Save: Choose a location and filename, then click “Save.”

5. Converting Existing Screenshots to JPG

What if you already have screenshots in PNG or another format and want to convert them to JPG? There are several ways to do this on your Mac.

5.1. Using Preview

Preview isn’t just for taking screenshots; it’s also a handy tool for converting images.

Open the Image in Preview: Double-click the image file to open it in Preview.
Export as JPG: Follow the steps outlined in Section 4.2 to export the image as JPG.

5.2. Using Automator

Automator is a built-in macOS application that allows you to create automated workflows. You can use it to batch convert multiple screenshots to JPG.

Open Automator: Open Automator from your Applications folder or use Spotlight Search.
Choose Application: Select “Application” as the type of document.
Add Actions:
- In the left sidebar, find “Find Finder Items” and drag it to the workflow area. Set the “Search:” dropdown to “Desktop” and the “for items whose:” dropdown to “Kind is Image.”
- Find “Change Type of Images” and drag it to the workflow area below “Find Finder Items.”
- Set the “Change to:” dropdown to “JPEG.”
Save the Application: Go to “File” and select “Save.” Give your application a name (e.g., “Convert to JPG”) and choose a location to save it.
Run the Application: Double-click the saved application to run it. It will automatically convert all images on your desktop to JPG.

5.3. Using Online Converters

If you prefer not to use built-in tools, several online image converters can convert screenshots to JPG. Some popular options include:

CloudConvert: A versatile online converter that supports many image formats.
Zamzar: Another popular online converter with a user-friendly interface.
OnlineConvertFree: A free online converter that supports batch conversion.

Simply upload your screenshot to the website, choose JPG as the output format, and start the conversion. Be cautious when using online converters and avoid uploading sensitive images, as they may be stored on the server.

6. Understanding Image Quality and Compression

When saving screenshots as JPG, it’s important to understand the relationship between image quality and compression. JPG uses lossy compression, which means some image data is discarded to reduce file size. The more compression applied, the smaller the file size, but the lower the image quality.

6.1. Quality Settings

Most image editing tools, including Preview, allow you to adjust the quality settings when saving as JPG. This setting determines the amount of compression applied. A higher quality setting retains more image data, resulting in a larger file size but better image quality. A lower quality setting results in a smaller file size but more noticeable compression artifacts, such as blurring or color distortion.

6.2. When to Use High or Low Quality

High Quality: Use high-quality settings when image quality is critical, such as when the screenshot contains detailed information or is intended for professional use.
Low Quality: Use low-quality settings when file size is more important than image quality, such as when sharing screenshots online or attaching them to emails.

6.3. Avoiding Repeated Compression

Each time you save a JPG image, it undergoes compression. Repeatedly editing and saving a JPG image can degrade the image quality over time. To avoid this, try to make all necessary edits at once and then save the image as JPG only once. If you need to make further edits, consider saving the image in a lossless format like PNG or TIFF until you’re finished, then convert it to JPG.

7. Optimizing JPG Screenshots for the Web

If you’re using JPG screenshots for your website or blog, it’s important to optimize them for the web. Optimized images load faster, which improves user experience and can boost your website’s search engine ranking.

7.1. Resizing Images

Large images take longer to load. Resize your screenshots to the appropriate dimensions for your website. For example, if your website displays images at a maximum width of 800 pixels, resize your screenshots to that width before uploading them.

7.2. Using Image Optimization Tools

Several tools can further optimize JPG images for the web by reducing file size without significantly affecting image quality. Some popular options include:

TinyJPG: A free online tool that uses intelligent lossy compression to reduce JPG file size.
ImageOptim: A free Mac app that optimizes images by removing unnecessary metadata and applying lossless compression.
Adobe Photoshop: A professional image editing tool with advanced optimization features.

7.3. Using Content Delivery Networks (CDNs)

A CDN is a network of servers that delivers content to users based on their geographic location. Using a CDN can significantly speed up image loading times, especially for users in different parts of the world.
