Image Cropper
Crop a rectangular region from an image by entering the position and size.
How to use the Image Cropper
Step 1 — Decide the region
- X is the distance from the left edge, Y from the top, both in pixels.
- Width and height set the size of the area you want to keep.
Step 2 — Enter the values
- Type the position and size into the four boxes.
- For a centred square, set equal width and height and adjust X and Y.
Step 3 — Upload and crop
- Drag your image in or browse to it.
- Press Process; the region is cut out on the server.
- If the box exceeds the image, it is trimmed to fit automatically.
Step 4 — Download
- The before/after preview shows the cropped result.
- Download it; files are deleted within an hour.
Frequently asked questions
X and Y are measured in pixels from the top-left corner; width and height are the size of the region to keep. Upload the image to see its full dimensions, then choose a region within them.
The crop is automatically clamped to the image edges, so you never get a broken or padded result.
No. Cropping simply keeps a region of the original pixels at full quality; only the dimensions change.
Yes — set width and height to the same value, for example 400 by 400, positioned where you want the square.
No. They are processed securely and deleted within an hour.
About the Image Cropper
This tool cuts a rectangular region out of an image and keeps only that part, discarding the rest. Cropping is one of the most common edits — removing unwanted edges, focusing on a subject, or producing a specific shape such as a square for a profile picture.
How cropping is specified
A crop is defined by four numbers: the X and Y position of the top-left corner of the region, measured in pixels from the top-left of the image, and the width and height of the region. Together these describe exactly which rectangle of pixels to keep. For example, on a 1000-pixel-wide image, an X of 100 and a width of 800 keeps the middle, trimming 100 pixels from the left and 100 from the right.
Why crop
Cropping improves composition by removing distractions at the edges and drawing attention to the subject. It is essential for fitting images into fixed shapes: social profile pictures are usually square, banners are wide and short, and thumbnails often need a specific ratio. Cropping also lets you salvage a good part of an otherwise imperfect photo. Because it only selects existing pixels, the kept region stays at full original quality.
Cropping versus resizing
Cropping and resizing are often confused but do different things. Cropping removes part of the image, changing what is shown. Resizing keeps the whole image but changes its pixel dimensions, scaling everything. To fit an image into an exact shape without distortion, you often crop to the right proportions first, then resize to the final dimensions. This tool handles the crop; the Image Resizer handles scaling.
Privacy and limits
Your image is uploaded securely, cropped, and offered for download, then deleted from the server automatically within an hour. The maximum upload is 25 MB. If your crop box extends beyond the image it is automatically clamped to the edges. To rotate or straighten an image use the Image Rotator, and to scale it use the Image Resizer.
