The tool cuts out stamp and signature images from one source PDF, cleans them from the background and unwanted strokes, and places them onto the pages of another target PDF. The output is a new PDF file with the added graphic elements, ready for saving.
When this is useful
An accountant needs to transfer the company's blue stamp and the director's signature from a scanned old contract into a new electronic form for a client. Another case: an HR department digitizes employee applications and wants to neatly insert a scanned signature into the proper field, having first removed the grey paper background around the flourish.
Step-by-step instructions
- First, upload the final PDF where you need to insert the images.
- Then upload the source document containing the original stamp and signature.
- On the source page, separately select a rectangular area for the stamp and one for the signature, dragging the frame corners to adjust.
- Wait for the automatic background removal and, if needed, manually clean the PNG image with the eraser using undo and redo.
- Click 'Add to Page', drag the processed pictures into exact positions, and save the whole document.
How to verify the result
After processing, be sure to zoom in and check the resulting stamp and signature images in the PNG preview. Make sure the eraser did not remove important thin lines of the signature and that no fragments of printed text remain around the stamp. If some strokes disappeared or unwanted dirt is left, undo the action and try cleaning the area again with a smaller eraser radius.
Important limitations
The tool works best for separating stamps and signatures from a light uniform background; the result may be imperfect when they overlap dense text or lines. The resulting raster image is just a graphic copy and has no legal force of a qualified electronic signature. The selection frame can always be stretched by its corners to crop the needed fragment more precisely before background removal.
