Your Signature, On Any Document, In Minutes

Adding a signature to a PDF used to mean printing the document, signing it by hand, and scanning it back. That workflow is slow, requires hardware, and produces a lower-quality result than a direct digital signature.

This tool lets you add your signature directly to a PDF in the browser. Draw it, type it, or upload an image of your handwritten signature. Position it exactly where it needs to go and download the signed document.

What Adding a Signature to a PDF Does

Adding a signature to a PDF embeds your signature as a visual element on the document page. The signature is placed at a specific location you choose and becomes a permanent part of the PDF. The result is a signed document that looks exactly like a printed-and-signed document, but produced entirely digitally.

Use cases include:

  1. 1

    Adding your signature to a contract received as a PDF attachment.

  2. 2

    Signing a job offer letter or employment agreement.

  3. 3

    Adding your signature to a rental or lease agreement.

  4. 4

    Signing a permission form or authorization document.

  5. 5

    Adding your signature to a client proposal or service agreement.

Any document that needs your signature can be signed in minutes without hardware.

How to Add Your Signature to a PDF

Three signature methods, one placement interface.

  1. 1

    Upload the PDF you need to sign.

  2. 2

    Create your signature: draw with mouse or finger, type your name in a signature font, or upload a saved signature image.

  3. 3

    Drag the signature to the correct location. Resize if needed. Download the signed PDF.

Upload, sign, place, download. Done.

How it actually works

Your signature is created and rendered as a transparent PNG.

The PNG is embedded in the PDF at the location you specify.

The output PDF contains the signature as a permanent visual element.

Technical explanation

Signature embedding uses PDF's image and annotation mechanisms.

The signature (drawn, typed, or uploaded) is rendered as a transparent PNG image.

The PNG is embedded as an image XObject in the PDF's resource dictionary.

The image is placed on the specified page at the specified coordinates using the PDF's content stream. The signature becomes part of the page content.

Why Direct Digital Signing Is Better

Eliminating the print-scan cycle saves time and produces better results.

You get a tool that’s:

  • No printer or scanner needed.
  • Cleaner output than a scanned signature.
  • Precise placement control.
  • Works on any device including mobile.

Digital signing is faster, cleaner, and more convenient than the print-scan alternative.

Signature Addition Features

  • Draw signature on canvas.
  • Type signature in script font.
  • Upload signature image.
  • Drag-and-drop placement.
  • Resize to fit signature lines.
  • Multiple signatures per document.
  • Secure processing with immediate deletion.

When not to use this tool

  • Signing a draft document. Always sign the final, approved version.
  • Not checking the placement. Open the downloaded PDF to verify the signature is in the correct location.
  • Using a very large signature image that doesn't fit the signature line.

Best practices

  • For a professional appearance, use a drawn signature rather than a typed one — it looks more like a real handwritten signature.
  • If you sign documents frequently, save a high-quality PNG of your signature to upload rather than redrawing each time.
  • For documents requiring date alongside signature, add both in the same session.

Alternatives

  • Direct digital signing is faster and produces better quality.
  • Print-sign-scan: 10–15 minutes, requires printer and scanner, produces a scan artifact.
  • Online signing: 2 minutes, browser only, produces a clean digital PDF.

Frequently Asked Questions

Find answers to common questions about our PDF tools

How do I add my signature to a PDF?

Upload the PDF, create your signature (draw it, type it, or upload an image), drag it to the correct location on the document, and download the signed PDF. The whole process takes about 2 minutes.

Where should I place my signature on a PDF?

Place it on the signature line or in the signature field designated in the document. If there's no designated field, place it at the bottom of the last page or wherever the document's context indicates.

Can I add my signature to multiple pages?

Yes. You can add your signature to any page or multiple pages in a single session. This is useful for documents that require initials or signatures on each page.

Can I save my signature for future use?

You can upload a signature image that you've saved from a previous session. Drawing a new signature each time is also quick — most people can draw a consistent signature in a few seconds.

Will the signature look like a real handwritten signature?

A drawn signature looks like your actual handwriting. A typed signature uses a script font that resembles handwriting. An uploaded signature image is exactly your real signature. For the most authentic appearance, drawing or uploading is recommended.
