3 Ways to Add Your E-Signature to a PDF

Different situations call for different signature styles. MyDigitSign gives you three options — all free, all private, all without uploads.

Why MyDigitSign is the Safest Free PDF Signature Tool

Most free PDF editor signature tools upload your documents to a remote server. That means your confidential contracts, NDAs, and personal information pass through someone else's infrastructure. MyDigitSign is different — it is the only tool that processes everything entirely inside your browser, with zero server involvement.

Is a Free Online PDF Signature Legally Binding?

Yes — and this is one of the most common questions people have when they sign a document online for the first time. An electronic signature is legally recognised under the ESIGN Act (United States), eIDAS Regulation (European Union), the Electronic Transactions Act (Australia), and equivalent legislation in over 180 countries.

For an e-signature to hold up legally, it generally needs to demonstrate intent to sign and a link to the signed document. A signature created and applied directly in your browser — with a timestamp and the resulting PDF stored only on your own device — meets those requirements for the vast majority of everyday agreements, including:

  • Freelance contracts and service agreements
  • Lease agreements and rental contracts
  • NDAs (non-disclosure agreements)
  • Employment offer letters and onboarding forms
  • Sales agreements and purchase orders
  • Consent forms and authorisation documents

For documents requiring a qualified electronic signature (QES) — such as some government filings or notarised documents — a certificate-backed signature may be required. Read our full guide: Are electronic signatures legally binding? →

Yes. MyDigitSign is 100% client-side. Your PDF is loaded and processed entirely inside your browser — nothing is ever sent to or stored on our servers.

No. MyDigitSign never adds watermarks. The downloaded file is a clean, standard PDF with only your document and your signature — nothing else added.

Does sign PDF online work on iPhone and Android?

Yes. Open this page in Safari (iPhone) or Chrome (Android), draw or type your signature using touch, upload your PDF, place the signature, and tap Download. No app installation required.

MyDigitSign supports PDF files up to 10 MB. This covers most standard documents including multi-page contracts, lease agreements, and business forms.
