Frequently Asked Questions

Is ConsultantsDen PDF Signer really free?▼

Yes, 100% free. No signup, no watermarks, no limits. We monetize through affiliate commissions if you upgrade to DocuSign/HelloSign/PandaDoc via our links.

Are signatures from the free tool legally binding?▼

For most informal agreements, yes. But for high-value contracts or regulated industries, you need an audit trail (timestamps, IP logs, tamper-proof certificates) which only paid tools provide.

Can I use this on mobile?▼

Yes! The PDF signer works on iOS Safari and Chrome Android. Touch to draw, pinch to zoom, tap to place signatures.

What happens to my PDF after I sign?▼

Nothing leaves your browser. The PDF is processed entirely client-side using pdf-lib and pdf.js. We never see your documents.

Can I add multiple signatures to one PDF?▼

Yes. Add as many signatures as needed across any pages. Each can be drawn, typed, or uploaded with background removal.

How does the affiliate model work?▼

If you click our links to DocuSign/HelloSign/PandaDoc and sign up, we earn a commission at no extra cost to you. This keeps our tools free.
