About Image Cropper
Drag a box over the part of the image you want to keep and crop to it, with optional fixed aspect ratios for common formats.
Cropping is lossless in the sense that it removes pixels rather than degrading the ones that remain โ but it does reduce resolution, and that has consequences. Cropping a 4000-pixel-wide photo down to a quarter of its area leaves a 2000-pixel image. That is still plenty for web use and marginal for large print, which is why heavily cropped photos look acceptable on screen and disappointing when enlarged.
Fixed aspect ratios matter when a platform will crop for you if you do not. Uploading a 4:3 photo where a square is expected means the platform decides what to discard, usually by taking the centre โ which frequently cuts through the subject. Cropping to the target ratio yourself keeps that decision.
Everything happens in your browser via the Canvas API, so the image is never uploaded. That matters for the photos people most often need to crop: documents, ID scans and personal pictures.
How to use Image Cropper
- Open your image and drag the crop box over the area you want.
- Set a fixed aspect ratio if the destination requires one.
- Apply the crop and download the result.
Frequently asked questions
Does cropping reduce image quality?
It removes pixels rather than degrading the remaining ones, so the kept area is unchanged. But the result has fewer pixels overall, so a heavily cropped photo has less resolution and will not enlarge or print as well.
Why crop to a specific ratio myself?
Because platforms crop automatically when the ratio does not match, usually from the centre โ often straight through the subject. Cropping yourself keeps control of what is kept.
Are my photos uploaded?
No. Cropping runs in your browser via the Canvas API, so the image never leaves your device. It also works with the network disconnected.
Can I undo a crop after downloading?
Not from the cropped file โ the removed pixels are gone. Keep your original and crop a copy.
