Frequently Asked Questions
QDoes my image get uploaded anywhere?
No. Cropping happens entirely in your browser using the Canvas API. Your image never leaves your device.
QCan I crop to an exact aspect ratio?
Yes — pick a locked ratio (1:1, 4:3, 3:4, 16:9, or 9:16) and the crop box will maintain that ratio as you resize it. Choose "Free" for an unconstrained crop.
QWhat resolution is the cropped output?
The output is cropped from the original full-resolution image, not the scaled-down preview — the live dimensions readout below the image always shows the true output pixel size.
About This Tool
The crop box is an absolutely-positioned overlay dragged and resized via Pointer Events. On download, the box's on-screen position is scaled up to the image's natural resolution, and the corresponding sub-rectangle is drawn onto a canvas via drawImage() with source-rectangle clipping, then exported at the chosen format and quality.
