Q: Which macOS versions are supported?

A: This guide is applicable to macOS versions 10.14 Mojave and later, including macOS Catalina, Big Sur, and Monterey.

Q: What tools can I use to resize photos on my Mac or MacBook?

A: You can use built-in macOS tools like Preview, as well as third-party applications like GIMP, Pixelmator, and Adobe Photoshop.

Q: Can I resize multiple photos at once using macOS?

A: Yes, you can use the Automator app to create a workflow that resizes multiple photos simultaneously. Choose “New Document,” select “Workflow,” add “Get Specified Finder Items” and “Scale Images” actions, and set the desired size.

Q: What are the best image formats to use for resizing photos?

A: The most common formats are JPEG, PNG, and TIFF. JPEG is best for photos with a lot of colors and detail, while PNG is suitable for images with transparency or less detail. TIFF is a lossless format that preserves image quality but has larger file sizes.

Q: How can I maintain the aspect ratio when resizing a photo?

A: To maintain the aspect ratio, make sure to lock the aspect ratio or enable the “constrain proportions” option in the resizing tool you’re using.

Q: Will resizing a photo affect its quality?

A: When increasing the size of a photo, the quality may decrease as the software interpolates additional pixels. When reducing the size, some detail may be lost, but the overall quality should remain acceptable. To maintain quality, consider using lossless formats like TIFF or high-quality compression settings for JPEG and PNG.

Q: How do I undo the resizing if I’m not happy with the result?

A: Most applications, including Preview, offer the option to undo your last action by clicking “Edit” and then “Undo” in the menu bar. To avoid losing your original photo, always save a copy of the resized image as a new file instead of overwriting the original.
