How to use Image Cropper
- Choose a PNG, JPEG or WebP image.
- Enter the crop rectangle as percentages of the original image; it must stay inside the source.
- Crop, inspect the result, and download PNG.
Crop a region without stretching it
Left and top specify where the rectangle starts, while width and height describe how much of the original canvas to keep. For example, left 25%, top 0%, width 50%, height 100% keeps the central vertical half. Coordinates are mapped to pixel edges and the output is not rescaled after cropping.
Know the output behavior
The crop preserves decoded transparency and exports PNG, which can be larger than the source JPEG or WebP. File size is a separate concern from pixel dimensions. The same 20 MiB file and 40-million-pixel limits as the other image tools apply. Source metadata and animation are not retained. Use image compression afterward if your delivery file needs fewer bytes.
Does changing width stretch the cropped region?
No. It changes the selected rectangle, then exports those pixels at the resulting dimensions.
