What it is for

Cropping means keeping part of an image and discarding the rest. It is the most basic edit and also the one that changes the result most, because it decides what the viewer looks at and what stays outside the frame.

It is used for two distinct reasons. One is aesthetic: moving closer to the subject, straightening a composition, fitting the photo to a square or landscape format. The other is practical: removing information that should not appear, such as the rest of the table around a photographed document or a piece of background that reveals where you were.

Here the crop is defined by coordinates: where the area you want to keep begins and how big it is. The origin (0,0) is the top left corner of the image.

How it works

  1. Upload the image you want to crop.
  2. Specify the position (X, Y) and size (width, height) of the area you want to keep.
  3. Click "Process" and download just that part of the image.

When to use it

Photographed documents

Cropping to the paper and cutting out the table behind leaves a far more presentable document before converting it to PDF.

Specific formats

Square for profiles, landscape for headers: cropping to measure stops the platform deciding where to cut.

Removing what does not belong

People in the background, number plates, papers with data: cropping is the safest way to keep them out, because they leave the file entirely.

Practical tips

  • Open the image in your system viewer to learn its full dimensions before working out coordinates.
  • If the area you specify runs past the edge, the crop adjusts itself to the real limits without erroring.
  • Cropping reduces the pixel count, so the resulting image is smaller. Be careful if you later need to print it large.
  • To hide something inside the image rather than at its edges, the right tool is pixelation, not cropping.

Frequently asked questions

How do I know the exact coordinates to crop?

Open the image in your system's viewer to see its full dimensions and work out the area you need from the top-left corner (0,0).

What happens if the area I specify goes beyond the image?

The crop is automatically clamped to the image's real boundaries, without throwing errors.
