Runs entirely in your browserAbout Image Crop
Cropping is the most common image edit besides resizing. Whether you're producing a square thumbnail for social, a 16:9 banner, a 4:3 product shot, or just trimming dead space, getting the right rectangle out of a larger image is a basic chore that shouldn't require a desktop image editor.
This crop tool uses `react-image-crop` for the selection UI — drag to draw a crop region, drag the handles to resize, and the live coordinates appear in the sidebar. Pick a preset aspect ratio to lock the rectangle proportions, or pick Free for any shape. The output format matches the source (PNG stays PNG, JPG stays JPG) so transparency is preserved where applicable. A thumbnail preview shows the cropped result before download. Everything runs in your browser.

Why are there preset aspect ratios?+
Many destinations require specific aspect ratios — Instagram squares (1:1), YouTube thumbnails (16:9), classic photo prints (4:3 or 3:2). Locking to a preset prevents you from accidentally cropping off-spec.
Does the output format match the input?+
Yes — JPG source produces JPG output (with high JPG quality), PNG source produces PNG output, and so on. Transparency is preserved where the format supports it.
Can I crop a transparent area?+
Yes — the checkerboard background of the preview indicates transparent regions. Your crop region can include transparent areas; they remain transparent in the output PNG.
What's the maximum image size I can crop?+
Same browser canvas limits as the resize tool — around 16384px in any dimension. For very large source images, resize first.
Is the image uploaded?+
No. Cropping is done locally via Canvas; nothing leaves your browser.
