How to Decrease Picture File Size on Mac
In today’s digital age, managing large picture files can be a daunting task, especially on a Mac. Whether you’re running out of storage space or need to send images via email, reducing the file size of your pictures can be a lifesaver. Here are some effective methods to decrease picture file size on Mac, ensuring you maintain quality while optimizing storage.
1. Use Preview to Resize Images
Mac’s built-in Preview app offers a quick and easy way to resize images. To do this, open the image in Preview, click on “Tools” in the menu bar, and select “Adjust Size.” You can then enter the desired width and height for your image. Remember to check the “Scale Proportionally” box to maintain the image’s aspect ratio. After adjusting the size, save the image by clicking “File” > “Save As.”
2. Utilize ImageMagick
ImageMagick is a powerful command-line tool that can be used to resize and compress images on Mac. To get started, download and install ImageMagick from its official website. Once installed, open the Terminal and use the following command to resize and compress an image:
“`
convert input.jpg -resize 800×600 -quality 85 output.jpg
“`
In this example, “input.jpg” is the original image, “800×600” is the new size, and “85” is the compression quality (0-100). Adjust these values according to your needs.
3. Use Image Resizer Apps
There are several third-party image resizer apps available for Mac that offer a user-friendly interface and additional features. Some popular options include:
– ImageOptim: This app automatically optimizes and reduces the file size of your images without losing quality.
– Resizing Image: This simple app allows you to resize multiple images at once with a batch processing feature.
– TinyPNG: This app uses advanced compression techniques to reduce the file size of PNG and JPEG images.
4. Adjust Compression Settings in Photoshop
If you have Adobe Photoshop installed on your Mac, you can adjust the compression settings to reduce the file size of your images. Open the image in Photoshop, go to “File” > “Save As,” and choose the desired file format (JPEG, PNG, etc.). In the “Save As” dialog box, click on the “Options” button and adjust the compression settings accordingly. For JPEG images, lower the quality setting to reduce the file size.
5. Use macOS Mojave’s Native Screenshot Compression
If you’re using macOS Mojave or later, you can take advantage of the native screenshot compression feature. When taking a screenshot, press “Shift” + “Cmd” + “5” to open the Screenshot menu. Click on the “Options” button and check the “Reduce Motion” box to automatically compress the screenshot.
By following these methods, you can effectively decrease picture file size on your Mac, ensuring you have enough storage space and a seamless experience while managing your images.
