How it works
The Image Cropper lets you select and cut a precise region from any photo directly in your browser. Drag a freehand selection box, lock to standard aspect ratios (1:1, 16:9, 4:3, 3:2, 9:16), or enter exact pixel coordinates for pixel-perfect crops.
Cropping is one of the most common pre-publication image tasks. Instagram square posts require 1:1, Instagram Stories require 9:16, Twitter/X header banners require 3:1, LinkedIn profile banners require 4:1, and product thumbnails often need to be exactly 300×300px. Meeting these requirements without Photoshop or a paid editor used to require at least three steps. Here it takes one.
How to use it: upload your image by clicking the upload area or dragging a file in. A selection handle appears over the canvas. Drag the corners or edges to define the crop region. For exact dimensions, type the pixel coordinates directly into the X, Y, Width, Height fields. Choose an aspect ratio preset to snap to a common format and drag to position. Click Crop, then Download.
Crop modes: freehand (any rectangle), aspect-ratio-locked (drag while constraining proportions), center crop (enter dimensions and the selection centers on the image automatically), and subject-aware crop (the tool detects the primary subject and centers the selection on it).
Output: the cropped region is exported at full resolution and quality in your chosen output format. The resulting pixel dimensions are displayed in real time so you always know the exact output size before downloading.
Privacy: your photo never leaves your device. The Canvas API performs the crop entirely in the browser. This is critical when cropping images that contain faces, identity documents, financial statements, or other sensitive content.
Frequently Asked Questions
- Yes. Enter the exact width and height values in the dimension fields. The selection snaps to those dimensions. You can then drag to reposition the crop area within the image before clicking Crop.
- No. The crop operation cuts a region from the original image data without recompression for PNG. For JPG output, the quality slider determines the compression level. The cropped pixels are unchanged — only the canvas boundary changes.
- Not directly — cropping is rectangular. For a circular crop, export as PNG and the Rounded Corners tool can apply a 50% border-radius to create a circle shape with transparent corners.
- Yes. Processing runs on the browser Canvas API, so the limit is your device's available memory. Images up to 20 megapixels work reliably on most devices. Extremely large files (50+ megapixels) may cause the browser to run slowly.
