When to use crop image
- Remove unwanted edges.
- Extract a product or document detail.
How it works
The selected source rectangle is drawn to a fresh canvas and re-encoded. Cropping discards pixels outside the rectangle.
Supported inputs and limits
Offsets and crop dimensions are whole pixels in the displayed, orientation-corrected image. The crop must stay within the source bounds. This rectangular crop does not remove objects inside the selected area.
Safety limits are 25 MiB / 32 megapixels on desktop and 12 MiB / 12 megapixels on touch or low-memory devices, with a maximum side of 8,192 pixels. A smaller limit does not guarantee success on every device. Clear the image to release its preview and output.
Common questions
Can I crop using a keyboard?
Yes. All four pixel controls are labeled numeric inputs and the preview follows those values.
Does the original file change?
No. The result is a separate file. Your source file remains unchanged.
