Crop an image
Drag a box, lock it to a ratio or type exact pixel coordinates. The crop happens in your browser.

Crop before you resize and before you compress
Cropping is the one operation that improves every other one. Every pixel of background you remove is a pixel that no longer competes for space in the compressed file, so a tight crop buys quality everywhere else in the image at no cost.
The order that wastes the least work is crop, then resize, then compress. Doing it the other way round means each step re-encodes what the previous step produced and lossy re-encoding compounds.
Shape matters more than size
Most complaints about an image being cropped badly by a platform are aspect ratio problems rather than size problems. A system that wants 16:9 and receives 4:3 has to cut something and it’ll not ask which part. Decide the shape here, where you can see what is being lost, rather than letting an upload form decide it for you.
The ratio buttons cover the shapes that come up most: square for profile pictures and feed posts, 4:5 for the tallest portrait a feed will accept, 16:9 and 9:16 for video thumbnails and vertical video, 3:2 for the native shape of most camera sensors.
The box is in real pixels
The preview is scaled to fit your screen, but the crop box is held in the source image's own coordinates and converted for display. That is why the numbers under the handles match the numbers in the fields and why a crop of a 6,000 pixel photo is exact even though you were looking at a 720 pixel preview of it.
Common questions
Does cropping lose quality?
The crop itself doesn’t: the pixels you keep are the pixels that were there. Saving the result re-encodes it, which costs a little if the output is JPG or WebP, so the quality control matters. Cropping a PNG and saving as PNG is genuinely lossless.
How do I crop to an exact size?
Type the numbers into the width and height fields. They’re in source pixels, so they mean exactly what they say rather than something scaled by the preview. If you need a shape rather than a size, use the ratio buttons, which lock the box so dragging a corner keeps the proportions.
Can I crop without a mouse?
Yes. Tab to the crop box and use the arrow keys to move it, Shift with an arrow to move it ten pixels at a time and Alt with an arrow to resize it. The numeric fields work too, which is often the fastest route for an exact crop.
Why does the ratio setting sometimes shrink my box?
Because locking a shape has to change one of the two dimensions and it shrinks rather than grows so the box can never be pushed outside the image by the constraint itself. Drag a corner afterwards to get back the size you want in the new shape.
Is the image uploaded to be cropped?
No. The image is decoded in your browser, the crop is taken from it in memory and the result is handed back as a download. There is no server involved, which also means the tool keeps working if you disconnect after the page loads.

All of them work the same way: the file is read in your browser and never uploaded.
