How to crop image
- Add a single image. It appears on a canvas with a selection box over it.
- Drag inside the box to move it, or drag any corner or edge handle to resize it.
- Optionally lock an aspect ratio — 1:1 for profile pictures, 4:5 for Instagram portrait, 16:9 for thumbnails.
- Press Crop & download to save just the selected area.
Why this runs in your browser
Almost every other free image tool uploads your file to a server, processes it there and sends it back. Crop Image does the work with the Canvas and File APIs that are already built into your browser, so the picture never leaves your device. That is faster for large files, it works on a plane, and it means there is no copy of your photo sitting in somebody's S3 bucket waiting to be deleted by a retention policy.
Frequently asked questions
Does cropping reduce image quality?
Cropping itself is lossless — it just discards pixels outside your selection. Quality loss only comes from the re-encode, so pick PNG output, or JPEG at quality 90+, if the source was high quality.
How do I crop an image to a perfect square?
Set the aspect ratio to 1:1. The selection box then keeps equal width and height no matter which handle you drag.
Can I crop to an exact pixel size?
Yes — the width and height of the current selection are shown live in pixels while you drag, and you can type exact values into the number fields.
Can I crop several images at once?
Cropping is inherently per-image because the interesting region is different in each one. For batch work, use the resize tool with "fit inside", or crop each image here — the tool stays loaded so it takes a few seconds each.
