Crop an image
Trim an image to the region you want by setting the crop box in pixels. Useful for removing what should not be in frame, and for hitting a shape a platform expects.

Why use this converter
- Exact pixel regions
Set the box numerically rather than eyeballing a drag.
- No quality cost
Pixels outside the box are removed; those inside are untouched.
- Reduces file size too
Roughly in proportion to how much area you cut.
- Forgiving bounds
A box overhanging an edge trims cleanly rather than failing.
When to crop
Removing what should not be in frame, or reshaping for a destination:
- Hitting a required aspect ratio: Social previews and cards expect particular shapes.
- Tightening a composition: Removing dead space around the subject.
- Trimming a scan: Cutting away the desk or scanner lid caught around the page.
- Reshaping before resizing: So the resize does not have to distort anything.
Crop first, resize second
When an image needs both, the order matters. Cropping decides which part of the picture survives; resizing decides how many pixels that part is stored at.
Doing it the other way round means resizing pixels you are about to throw away, and leaves fewer than you wanted in the area you kept. Crop first and the resize works only on what remains.
Aspect ratios platforms expect
Social previews, cards and thumbnails are usually displayed at fixed proportions, and anything that does not match gets cropped automatically — often straight through the middle of the subject.
Cropping deliberately to the shape a destination expects takes that decision back. It is the difference between a preview that frames what you intended and one that cuts someone's head off.
Frequently asked questions
Does cropping reduce quality?
No. Pixels outside the region are discarded and those inside are untouched.
Will it make the file smaller?
Yes, roughly in proportion to the area removed, since those pixels are no longer stored.
Should I crop or resize?
Crop to change what is in frame or its shape; resize to change the pixel dimensions. If you need both, crop first.
What if my crop box goes past the edge?
It is trimmed to the image rather than rejected. A box entirely outside the image is an error.
