Stamp ≠ watermark

What is the difference between a PDF stamp and a watermark?

A stamp is a precise, visible marking on a specific position on a specific page — like a rubber stamp on paper. A watermark is a faded text or image repeated diagonally across every page. They are different tools for different purposes.

Search for “pdf stamp” or “add stamp to pdf” and the results are dominated by watermark tools: PDF24, Smallpdf, Sejda, iLovePDF all open a watermark editor when you click through. If you need Paid on an invoice, Approved on a purchase order or your company stamp on a contract — at the right size, in the right corner, without covering the rest of the content — you need a stamp tool. PDFixer is built for exactly this workflow.

Quick answer: open the PDF in PDFixer, go to the Stamp / Signature panel, import or select your stamp image, position it on the page, save locally.

Open the PDF in PDFixer on Windows.

Most online tools labelled “pdf stamp” are actually watermark tools. PDFixer is built for the stamp workflow.

Can I use my own company stamp image in PDFixer?Yes. Import any PNG, JPG or BMP image as a stamp. If the image has a white or coloured background, PDFixer’s background removal tool strips it so only the stamp itself appears on the PDF page. Save the result as a permanent preset.

Can I reuse the same stamp on multiple PDFs?Yes. After importing and adjusting the stamp image, PDFixer saves it as a preset in the Stamp / Signature panel. On the next document you select the preset and place it in two clicks.

Can PDFixer also add a signature to the same PDF?Yes. PDFixer handles stamps, signatures and approval marks in the same Stamp / Signature panel. The workflow is identical for all three: import, remove background if needed, save as preset, place on page.
