Sign PDF

Choose one PDF, draw or type your signature, or use a PNG/JPG image. Place the signature on a page, adjust its size and color, then download the PDF.

PDF pages, signatures and added text are processed in your browser. The original document is kept unchanged. The draft is cleared when you leave the tool or refresh the page.

Add a date, single-line text, checkmarks and crosses. Select any mark to move, resize, recolor, edit or remove it. Without marks, Download returns an unchanged copy.

Open one nonempty PDF up to 100 MiB. Password-protected PDFs are not supported. This tool adds visual marks; it does not create certificate signatures or promise to preserve an existing digital signature's validity.
