Image Cropper

How to use the Image Cropper

Drop in an image. It appears on a canvas below the controls.
Drag across the image to draw a crop selection, or pick a ratio preset first to constrain it.
Fine-tune with the X, Y, width and height boxes if you need exact pixels, then press Crop.

Cropping versus resizing

These solve different problems and are often confused. Cropping removes part of the image — the remaining pixels are untouched, at their original resolution. Resizing keeps the whole image but changes how many pixels describe it.

If a photo is the wrong shape, crop. If it is the right shape but too large, resize. If it is both, crop to the ratio first and then resize — doing it in that order means the resize works on exactly the pixels you are keeping.

Ratios worth knowing

Ratio	Where it is used
1:1	Profile pictures, Instagram squares, app icons
16:9	Video, presentation slides, most screens
4:3	Older cameras, tablets, many print sizes
4:5	Portrait posts — the tallest most social feeds allow
1.91:1	Open Graph link previews on Facebook and LinkedIn

Profile pictures are usually displayed as circles even when stored square, so keep the subject away from the corners.

Frequently asked questions

Does cropping reduce quality?

No. The kept pixels are copied unchanged. The only quality consideration is the output format — a JPG source is re-encoded once, so use PNG input if you need pixel-exact output.

Can I crop on my phone?

Yes. The canvas supports touch, so you can drag a selection with your finger, then adjust the numbers for precision.

How do I crop a precise size?

Type the exact width and height into the boxes, then adjust X and Y to position the frame. The dragged selection and the numbers stay in sync.

Why is my cropped image still large in file size?

Cropping reduces pixel count but the format and quality are unchanged. Run the result through the Image Compressor if size matters.
