How to Insert and Embed a Signature into a PDF

When you receive a contract, you usually need to place your signature onto a specific signature line. Doing this digitally keeps the document clean and legible.

Methods to Insert Your Signature:

  1. Drawing: Draw your signature directly onto the document using your trackpad, mouse, or touchscreen.
  2. Typing: Type your name and apply an elegant handwritten-style font.
  3. Uploading an Image: Take a photo of your signature on white paper, save it as a PNG or JPG, and insert it as an image layer.

How to do it with PrivaPDF:

Our tool allows you to perform all three actions securely in your browser. Simply load your document into the Sign PDF Tool, select your signature method, place the signature box onto the designated signature line, and click Download.

Common questions

Can I insert a scanned image of my signature?

Yes. PrivaPDF allows you to select an image of your signature (ideally with a transparent background), drag it to the correct line, and save the document.

Does inserting a signature modify the PDF layout?

No. The signature is placed as an overlay layer, meaning your underlying text, tables, and formatting remain completely unchanged.

Is my file uploaded to a server?

No. All processing happens entirely in your browser using WebAssembly. Your file never leaves your device.
