How to use the Image Cropper
Set Crop Area or Aspect Ratio
Drag the crop box or choose a preset aspect ratio for social posts, thumbnails, profile photos, or web images. The crop image online preview updates immediately.
Download the Cropped Image
Export the cropped image when the framing looks right. Because processing is local, you can crop private images without sending them anywhere.
How this tool works
The component maps the selected rectangle to source pixels, draws only that region to a canvas, and exports the resulting bitmap locally.
- Engine: Canvas API source-region drawImage and export
- Supported input: browser-decodable still images
- Output: cropped image download
- Input
- A 1200 x 800 image with a centered 600 x 600 selection
- Output
- A square 600 x 600 crop
Limits, edge cases, and troubleshooting
Use it for avatars, thumbnails, and removing unwanted edges. Zoom carefully before applying small crops to high-resolution images.
- The decoded source and crop canvas must fit in browser memory.
- Animation and original metadata are not retained; crops outside image bounds are not meaningful.
When to use another workflow
Use a photo editor for perspective correction, non-destructive crops, guides, masks, print resolution, or batch work.
| Option | Best for | Trade-off |
|---|---|---|
| This browser tool | Quick, private, one-off work | Limited by browser memory and the documented feature set |
| Desktop or command-line tool | Batch jobs and repeatable automation | Requires installation and setup |

Yes. The photo is processed in your browser with local canvas tools, so it does not leave your device.
What aspect ratios can I use?
You can crop freely or use common aspect ratios for profile images, banners, thumbnails, and social media posts depending on the options available in the tool.
