What is Image Cropping?

Image cropping is the process of removing unwanted outer areas from a photo or graphic. It helps you focus on the most important part of an image, improve composition, or fit specific dimensions for social media, web, or print.

Why Crop Images?

Focus attention: Remove distractions and highlight your subject.
Fit aspect ratios: Prepare images for Instagram, Facebook, Twitter, or website banners.
Improve composition: Apply the rule of thirds or center your subject.
Optimize for web: Reduce file size and load times by cropping unnecessary parts.
Prepare for print: Fit images to ID cards, passports, or print layouts.
