About this image cropper
The image cropper trims an image to a rectangle you define by pixel coordinates, then exports just that region. Cropping removes unwanted edges and reframes the subject — tightening a screenshot, squaring a profile picture, or cutting a product shot down to its essentials.
Because it works by coordinates, you can crop precisely and repeatably, which helps when several images need the same framing. Unlike resizing, cropping changes what is in the frame rather than the scale of the whole picture, so the area you keep stays at its original detail.
Common uses
- Trim unwanted edges or whitespace from a screenshot or photo.
- Crop an image to a square or specific region for a profile or thumbnail.
- Cut a product or detail shot down to just the subject.
Helpful tips
- Cropping keeps the selected area at full detail; it does not enlarge what remains.
- Note the original dimensions so your crop coordinates land where you expect.
- Crop before resizing when you want a specific region at a specific final size.

Frequently asked questions
What is the difference between cropping and resizing?
Cropping cuts the image down to a chosen region, changing what is in frame. Resizing scales the whole image to different dimensions. They are often used together.
Does cropping reduce image quality?
No. The pixels you keep stay as they were. The file is smaller only because there are fewer pixels overall.
Is Image Cropper free, and does it work on mobile?
Yes. Image Cropper is free to use on JustBloc with no account or installation, and the page is designed to work on desktop, tablet, and mobile browsers.
