Crop Image

Private: nothing leaves your browser

Choose an image and drag the corners to crop it.

Drag the corners to cut an image down to the part you want, freehand or locked to a shape like square or 16:9. The exact pixel numbers are there if you need them. Your photo is cropped on your own device and never uploaded.

About cropping images

Cropping is the one edit that improves almost every photograph, and it is also the one that a form on some website will insist on before it accepts your picture. A profile photo has to be square, a banner has to be wide, and an ID upload wants a specific shape with the face filling it, which the passport photo maker handles end to end if that is the job. Dragging the corners here gives you exactly that, with the pixel dimensions shown as you go so you can match a requirement precisely.

The image is decoded, cut and re-encoded by your own browser using the same graphics engine that draws this page. Nothing is uploaded, nothing is stored, and no copy of your photo exists anywhere except on your device. That matters more for a crop tool than most: passport scans, screenshots of private messages and pictures of children are exactly what people crop, and exactly what should never be posted to a stranger's server.

Only the pixels inside the rectangle are kept, at their original resolution. There is no resampling, no scaling and no quality loss from the crop itself, so a crop of a sharp photo is still sharp. A JPEG is re-encoded because that is the only way to write one back, which is what the quality slider controls; a PNG is written losslessly and ignores it.

How to crop an image

  1. Drop an image on the box, click to choose one, or paste a screenshot straight onto the page.
  2. Drag inside the rectangle to move it, or drag any corner or edge to resize it.
  3. Pick a shape from the row of buttons to lock the proportions, or stay on Free for anything.
  4. Type exact numbers into Left, Top, Width and Height if you have a size to hit.
  5. Press Download the crop. The file is named after the original with the new size on the end. Cropping does not scale anything, so resize it afterwards if the pixel count still has to come down.

Common questions about cropping images

Does the photo leave my computer when I crop it?
No. The image is read, cropped and saved entirely by JavaScript on this page, and nothing is sent, logged or stored. The way to check a claim like this, on any site rather than only this one, is to press F12, open the Network tab and then do the thing: a tool that uploads has to make a request, and the request shows up there carrying your file. Here none does. Going offline and cropping anyway proves the same point from the other side, since the page keeps working.

Does cropping reduce the quality?
The crop itself does not: the pixels you keep are the original pixels at their original resolution, with nothing scaled or resampled. A JPEG has to be re-encoded to be written back out, and that step is lossy, which is what the quality slider is for. A PNG or WebP with transparency is written losslessly, so it comes back byte for byte identical inside the rectangle.

Can I crop to an exact pixel size?
Yes. Type the numbers into the Width and Height boxes and the rectangle follows, or drag roughly into place first and then correct the numbers. If a shape is locked, the height is worked out from the width so the proportion stays exact. To end up at a size larger than the area you selected you need the resize tool afterwards, since cropping can only ever remove pixels.

Can I crop without a mouse?
Yes. Tab to the crop area, then the arrow keys move it one pixel at a time, Shift and an arrow moves ten, and holding Alt while pressing an arrow resizes it instead. The four number boxes work the same way for anyone who would rather type than drag. On a phone the corners are dragged with a finger.

What does the transparent checkerboard behind the result mean?
It means those parts of the image have no colour at all, which is different from being white. A flat white background would hide the difference, and you would only find out when the image appeared on a dark page. Saving as JPEG fills transparency with white, because the JPEG format cannot store it.
