Are e-signatures as legally binding as pen on paper? In most of the world, including the US (under the ESIGN Act) and Europe (under eIDAS), the answer is a resounding yes. However, not all scenarios are created equal, and understanding the tiers of electronic signatures can save you from trouble in regulated contexts.

Basic vs. Advanced Signatures

Typing your name or drawing your signature using a tool like our Sign PDF tool constitutes a "Standard Electronic Signature." This is completely valid for B2B contracts, employment agreements, and non-disclosure agreements (NDAs).

However, some highly regulated documents — like wills, property deeds, or court documents — may require an "Advanced" or "Qualified" Electronic Signature, which involves a cryptographic certificate issued by an official trusted authority to mathematically prove the signer's identity and certify that the document hasn't been altered after signing.

What About Timestamping?

A timestamp proves that a signature was applied at a specific date and time, which is important for time-sensitive contracts and compliance records. Even without cryptographic timestamps, keeping records of when each party signed (via email confirmation or document management software) is considered best practice.

Common Valid Use Cases for Standard E-Signatures

• Employment contracts and offer letters
• Software licensing agreements and Terms of Service
• Sales contracts, vendor agreements, and purchase orders
• Non-disclosure agreements (NDAs)
• Lease agreements in many jurisdictions (check local law)

After You Sign: Next Steps

After signing a PDF digitally, consider adding a password to prevent further editing. You can also compress the PDF before emailing it to keep file sizes manageable. If you need to combine the signed document with others, use our Merge PDF tool.
