Crop Image
Drag a box around the part you want and throw away the rest.

Everything happens on your device — your files are never uploaded.
What this does
Crop Image cuts a rectangle out of your picture and discards everything outside it. You drag the box over the part you want; the on-screen selection maps back to the image's native resolution, so the pixels inside your box are copied through unchanged with no scaling or resampling.
The result is encoded as a PNG. PNG is lossless, so the kept pixels stay bit-exact and any transparency carries over. The original file's EXIF metadata is not copied into the output.
How it works
- 1 Drop your image.
- 2 Drag the box to move it, drag a corner to resize. Pick an aspect ratio to lock the shape.
- 3 Download the cropped image.

Frequently asked
Is the crop pixel-accurate? +
Yes. The on-screen box is scaled back to the image's full resolution, so the output matches your selection exactly, down to the pixel.
Does cropping reduce quality? +
No. The kept pixels are copied through without resizing or recompression, and the PNG output is lossless, so they stay identical to the source.
What format is the output? +
PNG, regardless of the input format. PNG is lossless and supports transparency, so nothing inside the crop is degraded.
Does it keep transparency? +
Yes. PNG has an alpha channel, so transparent areas of a PNG or other transparent source stay transparent in the crop.
What happens to EXIF and other metadata? +
It is dropped. The crop is re-encoded from the raw pixels, so camera data, GPS tags, and color-profile information do not carry into the PNG.
What can I do with the aspect ratio? +
Leave it on Free to drag any shape, or pick a fixed ratio to lock the box so it keeps those proportions as you move and resize it.
Is my image uploaded anywhere? +
No. The image is read, cropped, and encoded in your browser. Nothing is sent to a server, and there is no sign-up or watermark.
Which formats can I open? +
Any image your browser can decode, including JPEG, PNG, WebP, GIF, and AVIF. Whatever you open, the cropped output is saved as a PNG.
