How to use it

  1. 1
    Add an image

    Drag a JPG, PNG or WebP file onto the drop zone or click to choose one.

  2. 2
    Frame your crop

    Drag the selection box to move it and the corner handle to resize, or pick an aspect-ratio preset.

  3. 3
    Crop and download

Drag, snap and crop

Move and resize the selection box over your image to frame exactly the part you want. Lock it to a 1:1, 16:9 or 4:3 ratio for avatars, thumbnails and banners, or crop freely. The pixel size of the crop is shown as you adjust.

Private and free

Cropping happens entirely on your device with the canvas — no upload, no account, no watermark. The cropped image is generated locally and downloaded straight to your computer.

Frequently asked questions

Is my image uploaded to a server?

No. Cropping runs entirely in your browser; your image never leaves your device.

Can I crop to a fixed aspect ratio?

Yes — choose 1:1, 16:9 or 4:3 to keep the selection locked to that ratio, or crop freely.

Does cropping reduce quality?

Cropping copies the selected pixels as-is, so there is no quality loss beyond the chosen output format’s encoding.

Which formats can I crop?

JPG, PNG and WebP. You can keep the original format or export the crop as JPG or PNG.
