How to crop an image
- Pick an image — the crop box starts centered.
- Use a preset ratio (square, 16:9, 4:3, story) or type exact X/Y/width/height.
- The dimmed preview shows exactly what will be kept. Click Crop, then Download.
Common crop sizes
- Instagram post: 1:1 square
- YouTube thumbnail: 16:9
- Stories / Reels / TikTok: 9:16
- Classic photo print: 4:3
Benefits
- Crop to any area or a preset ratio like 1:1, 16:9, 4:3 or 9:16.
- Great for getting a photo to the exact shape a platform wants.
- Runs in your browser, so images stay private.
- Free and unlimited.
Limitations to know
- Cropping removes pixels, so you cannot recover the area you cut later.
- Cropping tightly then enlarging the result reduces sharpness.
- It changes framing, not exposure or color.
Common mistakes to avoid
- Cropping too tight and leaving no margin for different display sizes.
- Using the wrong aspect ratio for the target platform, so it gets re-cropped anyway.
- Cropping the only copy of an original instead of working on a duplicate.
Alternatives

Is my image uploaded?
No — cropping happens entirely on your device.
Does cropping lose quality?
No — the kept pixels are untouched; you're just removing the rest.
