When working with images on a Mac, file sizes can quickly become too large, especially if you’re dealing with high-resolution photos. Whether you need to upload images to a website, share them via email, or save space on your hard drive, reducing image file sizes is crucial. Fortunately, there are several ways to compress an image on a Mac without sacrificing quality. In this guide, we will explore 5 free methods, including using built-in Mac apps, online tools, and free applications, to help you compress images easily.
Built-in App to Compress Images on Mac
The simplest way to compress an image on a Mac is by using the Preview app, which comes pre-installed on all macOS devices. With Preview, you can quickly reduce the file size of your images without needing any additional software.
How to Compress an Image with Preview
- 1. Open the Image in Preview:
- 2. Navigate to Export Options:
- 3. Select File Format:
- 4. Adjust Quality Slider:
- 5. Save the Compressed Image:
Right-click the image file you want to compress and select Open With, then choose Preview. Alternatively, you can double-click the image to open it if Preview is set as your default image viewer.
In the Preview menu at the top of your screen, click File and then select Export. A new window will pop up with export settings.
In the export window, choose your preferred file format (e.g., JPEG, PNG) from the Format drop-down menu. If you’re looking for a smaller file size, JPEG is generally a good option as it offers compression without drastically reducing quality.
Below the format selection, you will find a Quality slider. Moving the slider toward Least will reduce the file size, while moving it toward Best will maintain more image quality but result in a larger file. Find a balance between file size and image quality by adjusting this slider.
Once you’re satisfied with the quality settings, click Save. Your compressed image will be saved in the location you specified.
Using Preview, you can efficiently compress an image on a Mac without needing to download any additional software.
