Cropped stamp
Upload an image to preview the cropped stamp.
How it works
Remove the surrounding page without redrawing the stamp
A crop keeps the original stamp pixels and removes everything outside the selected area. Use a rectangle for square seals and document marks, or a round mask for circular and oval stamps.

Refine and download
Crop again when needed, check the live preview, and save the final PNG.
Crop cleanly, even when the stamp sits on a busy page
Start with a generous selection so no border is lost, then tighten the crop with the handles or exact pixel fields. For difficult scans, enable another crop pass and refine the result.
Start wide, then refine
Keep the whole border in the first selection. A second crop can remove the remaining margin.
Match the stamp shape
Use a rectangle for square marks and a round mask for circular or oval seals.
Use pixels for repeatable crops
Exact left, top, width, and height values help when a batch uses the same layout.
Keep source documents private
Cropping runs locally in your browser; the source image is not uploaded for processing.
Stamp cropping questions
Practical answers about crop shapes, pixel coordinates, repeated crops, and document privacy.
Can I crop both rectangular and circular stamps?
Yes. Rectangle keeps every pixel inside the selected box. Round / oval makes the pixels outside the selected ellipse transparent.
How do the precise crop values work?
Left and top set the selection origin from the image's top-left corner. Width and height control the output dimensions in pixels.
When should I crop the stamp again?
Use another pass after a rough crop, especially when the original scan is large or the final edge needs closer adjustment.
Is my stamp image uploaded?
No. Cropping and PNG generation run in your browser, so the source image stays on your device.
Continue your stamp workflow
If the mark still includes paper or text, first extract stamp from image. Then rebuild it in the stamp maker, explore new layouts with stamp generators, or convert another image with the stamp maker online free.
add stamp background: Place a solid or translucent color behind the transparent pixels while preserving the original stamp size and ink.
