PDF Signature Adder
Draw a signature with your mouse or finger and place it anywhere on a PDF page.
About this tool
Draw a signature with your mouse or finger and place it anywhere on a PDF page. It runs entirely in your browser using open-source PDF libraries, so your document is processed on your own device and never uploaded to a server. That makes it a fast, private option any time you need to draw a signature and place it on a page.
How to use it
- Upload the PDF you need to sign.
- Draw your signature with your mouse, stylus, or finger.
- Place it on the page and download the signed PDF.
Tips
- Draw slowly for a cleaner signature line — quick strokes can look jagged at small sizes.
- Resize your signature before placing it if it looks too large for the page.
FAQ
Is my signature stored anywhere?
No, it's drawn and placed locally in your browser and never uploaded.
