Printing a PDF just to sign it and scan it back is the productivity equivalent of a fax machine. You don't need to. Signing a PDF online is faster, free, and — done right — legally binding. Here's how.

Signing a PDF yourself

If a document has landed in your inbox and you just need to sign it:

  1. Upload the PDF to an e-signature tool (with ToroDocs you can start free, no card required).
  2. Place your fields — drop a signature box, and add the date or text fields anywhere you need them.
  3. Add your signature. You have three options: draw it with a mouse or finger, type it and pick a signature-style font, or upload an image of your signature.
  4. Download the signed PDF. The finished file is sealed and ready to send.

That's it — usually under two minutes, no software installed.

Sending a PDF to someone else to sign

More often, you need another person to sign — a client, a contractor, a new hire. The flow is just as quick:

  1. Upload the document and drag on the fields each signer needs to complete (signature, initials, date, text).
  2. Add recipients by name and email. Need them to sign in a specific order? Turn on sequential routing.
  3. Send. Each person gets a secure link to their own signing session — no account required on their end.
  4. When everyone has signed, you both receive the sealed, completed PDF automatically.

Make sure it actually holds up

A signed PDF is only as good as the record behind it. Look for a tool that:

  • Captures consent to sign electronically (ESIGN/UETA).
  • Records an audit trail — views, consent, and signatures with timestamps and IP addresses.
  • Produces a tamper-evident file. ToroDocs seals every document with a SHA-256 hash and a Certificate of Completion, and offers public verification at /verify.

If your tool just flattens an image onto a page with none of that, you have a picture of a signature — not a defensible agreement. (For the full legal picture, see Are electronic signatures legally binding?)

Why not just use free PDF editors?

Basic PDF editors can drop a signature image onto a page, but they don't capture consent, build an audit trail, or seal the result — so the signature is hard to defend if challenged. A purpose-built e-signature platform does all of that automatically, and ToroDocs' free plan covers real documents each month at no cost.
