Complete Guide to Electronic PDF Signing & Document Legality

An electronic signature (e-signature) is a legally recognized method of indicating consent, approval, or execution on digital contracts, agreements, real estate leases, and invoices. Processing document signatures without printing, scanning, or manual courier dispatch accelerates enterprise deal execution by over 80%.

International Legal Validity

  • United States: Fully valid under the Electronic Signatures in Global and National Commerce Act (ESIGN Act, 15 U.S.C. § 7001) and Uniform Electronic Transactions Act (UETA).
  • European Union: Enforceable across all 27 member states under the eIDAS Regulation (EU No 910/2014).
  • India: Legally binding under Section 10A of the Information Technology (IT) Act, 2000.
  • United Kingdom: Recognized under the Electronic Communications Act 2000.

Zero-Knowledge Browser Privacy

  • 100% In-Browser Execution: Unlike commercial cloud signing SaaS tools that upload confidential contracts to third-party servers, our tool processes PDF byte buffers entirely inside your device's browser memory using pdf-lib and PDF.js.
  • Strict Data Privacy: Non-Disclosure Agreements (NDAs), tax documents (W-9, Form 16), and employee contracts never touch any external server.

Frequently Asked Questions (FAQs)

Can I create my signature by typing my name?

Yes! Our signing suite provides three flexible methods: Draw with mouse, stylus, or touchscreen; Type using beautiful cursive calligraphy fonts; or Upload a high-resolution PNG image of your pre-existing handwritten signature.

Can I place multiple signatures across different pages of a multi-page PDF?

Yes. Use the pagination controls (« Prev and Next ») to navigate to any page within your document. Drag and resize your signature stamp precisely over the signature line, initial boxes, or date fields.

Will the output PDF lose formatting or visual quality?

No. The underlying vector structure, embedded fonts, and resolution of your original PDF are strictly preserved. The signature is seamlessly rasterized and embedded as an authentic PDF overlay layer.
