Question 1

Are my images uploaded to a server?

Accepted Answer

No. Image decoding, crop selection and export all happen locally in your browser — files are never uploaded to any server, secure and fast.

Question 2

How do I crop a square avatar?

Accepted Answer

Choose the 1:1 ratio so the crop box locks to a square, then drag to adjust position and size and export.

Question 3

Can I crop precisely by pixel?

Accepted Answer

Yes. Besides drag selection, you can enter the X, Y coordinates and width/height in pixels in the parameter panel for precise cropping.

Question 4

Will cropping a transparent PNG keep the transparent background?

Accepted Answer

Yes. Exporting as PNG or WebP keeps the alpha channel; if you export as JPG or BMP, transparent areas are filled with the chosen background color.

Question 5

Does GIF animation work?

Accepted Answer

Browsers typically decode only the first GIF frame, and this tool crops that frame. To process every frame, split the GIF or extract frames first.

Question 6

Why does a huge image fail to export?

Accepted Answer

Browser canvases usually cap each side around 8192–16384 pixels. Oversized sources or output sizes will fail — shrink the original or lower the target size.

Question 7

How do I crop the same region on many images?

Accepted Answer

Drop multiple images, frame the first one, then use “Batch download ZIP”. Every image gets the same X/Y/width/height; smaller images pad or clamp depending on “Allow padding”.
