Image Cropper

Cut a photo down to the part that matters, free-form or to a fixed shape. Your image is processed in this browser tab.

Crop an image

Drag an image here, or choose one

JPEG, PNG, WebP, GIF, BMP or AVIF, up to 25.00 MB.

Your image is processed in this browser tab. It is not uploaded.

How to use it

  1. Drag an image onto the box above, or choose one from your device.
  2. Drag the selection to move it, and its corners or edges to resize it. The thirds grid helps line a subject up.
  3. Lock a shape — square, 4:3, 3:2 or 16:9 — if the crop has to fit a particular slot, or type exact numbers.
  4. Choose the output format, then select Crop image and download the result.

What this tool does and does not do

It keeps the part of the image inside your selection and discards the rest. The pixels you keep are not scaled or resampled, so the kept area is pixel-for-pixel what it was.

  • It crops, it does not scale. The output is exactly as many pixels as your selection. To change the dimensions afterwards, use the Image Resizer.
  • A smaller file is likely, not guaranteed. Format and quality affect the result as much as the area does.
  • The selection never leaves the image. Dragging or typing past an edge stops at the edge instead of producing a crop with blank space in it.
  • Transparency is kept when the output is PNG or WebP, and you are warned before JPEG would flatten it.
  • Limits. Files up to 25.00 MB, and a minimum crop of 8 pixels on a side.
  • Metadata is removed and animated files are reduced to their first frame.

Cropping, resizing or compressing?

Crop to change what is in the picture. Resize to change how many pixels it has. Compress to change how large the file is. They are often used together: crop to the subject, resize to the dimensions a page needs, then compress to fit an upload limit.

Common questions

Can I crop to an exact size?
Yes. The four number fields set the selection to the pixel: left, top, width and height. They stay in step with the box you drag, so you can rough it out by eye and then correct the numbers. Anything outside the image is pulled back inside rather than rejected.
Why do the side handles disappear when I lock a shape?
Because dragging one side of a fixed-shape box could only work by stretching it, which is exactly what locking the shape is meant to prevent. With a shape locked you get the four corner handles, each of which resizes the whole box from the opposite corner.
Does cropping reduce the file size?
Usually, since there are fewer pixels to store, but it is not guaranteed: the output format and quality matter too. The tool reports the real size and says plainly when the result is not smaller. For a specific file size, use the Image Compressor.
Can I use it without a mouse?
Yes. Tab to the selection and move it with the arrow keys, holding Shift to move ten pixels at a time, and use the number fields to set the size. Everything the tool does is reachable from the keyboard.
Does cropping lose quality?
The pixels you keep are not resampled, so cropping itself does not soften the image. Saving as JPEG or WebP re-encodes them, which does cost a little quality; choose PNG if you need the kept pixels to stay exact. The smallest crop is 8 pixels on a side.
Is my image uploaded anywhere?
No. The image is decoded, cropped and re-encoded by your own browser, and the download comes from the copy made in the tab. Celveri has no upload endpoint and no database. You can watch your browser’s network tools while you crop to confirm it.
