Does my image get uploaded?

No. The crop runs inside your browser on your own device — the image never leaves your computer and never reaches a server.

How exact is the crop?

To the pixel. The rectangle you see on the preview — position and size — is computed by the same function that performs the crop, so what you selected is exactly what you download. The readout under the preview shows the precise pixel values before you commit.

Does cropping reduce quality?

The cropped pixels themselves are copied exactly — cropping never resamples or blurs. For JPG and WebP the cropped region is then re-encoded to save it, and that encode quality is tuned per image against a measured perceptual score, which is shown with the result. PNG is different: it is stored losslessly, every pixel identical.

What if I select the whole image?

You get your original file back unchanged — the tool tells you nothing was cropped instead of silently re-encoding it for no reason.

What about photos taken on a phone sideways?

The image is shown the way you'd see it in any viewer — orientation metadata is applied before you select — so the region you drag is the region you get, never a rotated surprise.

Which formats are supported?

JPG, PNG, and WebP. GIF and SVG are not supported yet — the tool tells you immediately if you drop one instead of failing silently.
