How to add a signature to a PDF
Adding a signature to a PDF comes down to two things: creating a signature you are happy with, and placing it accurately on the page. This guide covers all three ways to create one and how to reuse it cleanly across documents.

Step by step
- 01
Open your PDF
Upload the PDF to the DocSignHub signer. It opens in your browser and is never sent to a server.
- 02
Create your signature
Choose how to make it: draw with your mouse or finger, type your name in a handwriting font, or upload an image of your real signature.
- 03
Place and size it
Drag the signature onto the signature line and resize it so the width matches the space provided. Repeat on any other pages that need it.
- 04
Download
Export the signed PDF. The signature is flattened into a standard file that opens anywhere.
Drawn, typed, or uploaded — which to choose
Each method has a sweet spot:
- Draw — most natural on a touchscreen; best for an authentic-looking signature on a phone or tablet.
- Type — fast and perfectly consistent; ideal on a desktop with no touchscreen.
- Upload — the most realistic option, using a photo of your actual pen-on-paper signature.
Getting a clean signature image
If you upload a photo of your signature, a little prep makes it look professional. Sign in dark ink on plain white paper, photograph it in even light, and crop close to the signature.
A signature on a white background will carry that white box onto the document. For the cleanest result, use an image with a transparent background (a PNG) so only the ink shows over the document.
Reusing the same signature
If you sign documents regularly, keep a saved signature image on your device — a cropped PNG of your handwritten signature works best. You can upload the same file each time for a consistent, recognizable signature without re-drawing it.
