Common questions: how to crop image on Mac (FAQ)
Can I crop without losing quality?
Cropping itself doesn’t reduce image quality, but reducing overall pixel dimensions can make an image look softer if you enlarge it later. For screen use, cropping on Mac with Preview or Toolixr is safe — just check the final pixel size.
Which is best: built-in tools or an online cropper?
Use built-in tools (Preview, Photos, Quick Look) for offline, quick edits. Choose an online Mac image crop tool when you need cross-platform access, batch speed, or exact pixel outputs for multiple images.
What file format should I save after cropping?
Save photographs as JPEG for smaller files and wide compatibility. Use PNG for screenshots or images needing transparency. Toolixr allows you to download in common formats after cropping.
