Crop image

Crop JPG, PNG, WebP and GIF to a free selection or preset ratio right in your browser — pixel-exact, nothing uploaded.

How to crop an image

  1. Drop or pick a JPG, PNG, WebP or GIF file.
  2. Drag the selection or pick a ratio preset — fine-tune the exact width, height and position with the number fields.
  3. Crop and download — all on your device.

Why crop images?

Cropping reframes a shot, drops dead space and hits the exact aspect ratio a layout or platform needs. OptImg crops in real image pixels — the on-screen selection maps precisely to the output — entirely on your device, with no upload and no size limit.

Frequently asked questions

Are my images uploaded to a server?
No. Cropping runs entirely in your browser with WebAssembly — your image never leaves your device, and there are no size or file-count limits.
Can I crop to an exact size or ratio?
Yes. Pick a preset ratio (1:1, 4:3, 16:9 and more) or type the exact width, height and position in pixels — the visual selection and the number fields stay in sync.
Does cropping keep animation?
Yes. Every frame of an animated GIF is cropped to the same rectangle, and delay and loop are preserved.
