How to E-Sign a PDF — Request & Add Digital Signatures Free | PDF AI Work Blog

PDF AI Work Team·July 31, 2026

Need legally binding electronic signatures? The E-Signature tool lets you self-sign documents or request signatures from others — with digital certificate embedding and audit trails.

Self-Signing vs Requesting Signatures

  • Self-sign: Sign your own documents instantly — draw, type, or upload signature
  • Request signatures: Send documents to others for signing with email notifications and tracking
  1. Open E-Signature
  2. Upload your PDF
  3. Add signature fields where needed
  4. Self-sign or send to recipients
  5. Download the signed PDF with audit trail

For quick signing without the request workflow, use Sign PDF. For document security: Protect PDF.

Free, no signup for basic signing. E-sign your PDF now.
