Question 1

Is PDF Fill & Sign free?

Accepted Answer

Yes, completely free. No account, no signup, and no paid tiers -- fill and sign as many documents as you need.

Question 2

Are my documents private?

Accepted Answer

Yes. Everything runs in your browser -- your PDFs never leave your device and nothing is uploaded to any server. Close the tab and the files are gone.

Question 3

What documents can I fill and sign?

Accepted Answer

Construction documents including California lien waivers (conditional/unconditional, progress/final), AIA-style forms, change orders, submittal cover sheets, and IRS forms (W-9, W-4, 1099-NEC). You can also upload your own PDF.

Question 4

Do I need to create an account?

Accepted Answer

No account is required. Open the tool, fill the form, add your signature, and download -- nothing to sign up for.

Question 5

What is the difference between a conditional and unconditional lien waiver?

Accepted Answer

A conditional lien waiver becomes effective only when the payment check clears -- protecting you if the check bounces. An unconditional waiver takes effect immediately upon signing, so use it only after you have confirmed payment. Both forms are available as pre-filled templates.

Question 6

Can I sign construction documents electronically?

Accepted Answer

Yes. Electronic signatures are legally valid for lien waivers and AIA forms in most US states under ESIGN and UETA. PDF Fill & Sign lets you draw, type, or upload your signature and embed it in the document.
