How do I move the crop box?

Click and drag inside the existing rectangle to move it. Drag any of the four corner handles to resize. You can also click anywhere outside the box to start drawing a new selection.

What aspect ratios are available?

Free (no lock), 1:1, 4:3, 3:2, 16:9 and 9:16. Pick one before drawing or resizing and the rectangle will snap to that ratio.

Is the crop pixel-exact?

Yes. The crop is taken from the original full-resolution image pixels — the preview is just a smaller view for convenience.

Does it support transparent PNGs?

Yes. PNG and WebP output preserve alpha. JPEG output fills transparent areas with white.

Are my images uploaded?

No. Cropping is 100% client-side using the Canvas API.
