Why Sign PDFs Online Instead of on Paper

Signing PDFs online is faster, keeps the document usable, and works anywhere. FiloTool doesn't flatten your PDF into an image, so vector content and selectable text stay intact wherever the original PDF supports it.

A Few Things Worth Knowing

This is a visual signature, not a certificate-based digital signature. It doesn't include identity verification or an audit trail — it simply places your signature image onto the PDF.

Password-protected PDFs need to be unlocked first using Unlock PDF
You can add initials too
Your files aren't kept around

When to Use This vs. a Formal E-Signature Platform

If you're signing a lease, a form for a client, or an internal document, FiloTool's visual signature is quick and sufficient. But if you're closing a deal that needs legal enforceability with identity verification and a signing audit trail, you'll want a certificate-based e-signature platform instead.
