Fill & Sign PDF — Complete Any Form in Your Browser (No Uploads, No Server)

Professionals fill PDF forms every day — tax documents, contracts, applications. Most tools force you to upload sensitive documents to a server. That's unacceptable for legal and financial paperwork.

So I built Fill & Sign PDF: a tool you open in your browser, fill in any PDF form, add a signature, and download — all 100% client-side. No uploads. No accounts. No subscriptions.

The problem

Adobe Fill & Sign costs $12.99/month. Smallpdf charges $12/month. Both upload your documents to their servers. For tax forms, lease agreements, or medical documents, that's a privacy risk you shouldn't have to accept.

The solution: 100% in-browser

The entire app is a single HTML file. It uses:

  • pdf-lib for reading PDFs, extracting form fields, and embedding signatures
  • pdf.js for rendering the PDF preview in the browser

That's it. No server. No API. No data ever leaves your machine.

Features

  • Fill any PDF form field (text, checkboxes, dropdowns)
  • Draw or type a signature and place it on the PDF
  • Preview the filled PDF before downloading
  • Works offline in any modern browser
  • Dark mode support
  • No sign-up, no account, no tracking

Pricing

$9 one-time. No subscription. No recurring charge. Compare that to Adobe's $12.99/month ($156/year) or Smallpdf's $12/month.

Built the same way as Resume PDF Builder and PDF Tool — all client-side, all privacy-first.
