Sign PDF - How To Guide

Learn how to use sign pdf. 100% free, no installation required.

Signing a PDF electronically saves the print-sign-scan cycle and produces a cleaner document than a photograph of paper. Here is how to add a signature that looks right and sits in the correct place.

  1. Upload Files

    Add the PDF and open the signature tool. Draw your signature, type it, or upload an image of one you already have.

  2. Set Options

    Place it on the page, resize it with the handles, and add a date or printed name if the document calls for one.

  3. Download

    Download the signed PDF. The signature is composited into the page, so it displays everywhere.

Tips & Best Practices

  • Drawing on a touchscreen or trackpad gives a far more natural line than a mouse.
  • If you photograph a signature, use a dark pen on white paper, crop tightly, and convert to a transparent PNG.
  • Save the signature so you can reuse it — redrawing it each time gives inconsistent results.
  • This produces a visible signature image, which most agreements accept. A process that explicitly requires a certificate-based digital signature needs a different kind of service.
