    Why Crop a Screenshot on Mac?

    There are many reasons to crop screenshots on a Mac. As mentioned earlier, trimming off the portion of a screenshot containing personal information or sensitive data (address, credit card information, etc.) can help protect your privacy. You could also crop out unnecessary portions of a screenshot to reduce the file size.

    If a screenshot contains tiny text, chopping off the nonessential parts helps highlight important information and improves readability. Using the built-in Screenshot app, you can crop new, old, regular, or scrolling screenshots on your Mac.

    The app simplifies the process of capturing and cropping screenshots and screen recordings. If you’re unsure where to find the Screenshot app, you can use the Preview app, third-party tools, and online services.

    Cropped Mac Screenshots: Focus on What Matters

    Any of the applications and tools will help crop screenshots so that they contain only relevant information. We recommend using the Screenshot or Preview app because, unlike online editors, they’re easier to use. Additionally, you can quickly crop screenshots without an internet connection. Cropping screenshots in the Photos app is also straightforward, but it entails importing and exporting the screenshots.
