Gone are the days when closing a contract required printing dozens of pages, signing with a ballpoint pen, scanning, and emailing back. Electronic signatures are recognized by law across almost all global jurisdictions. However, many business owners wonder: is a signature drawn on a browser screen truly legally enforceable in court? Here is what legal frameworks like the US ESIGN Act and European eIDAS require.
#1The Legal Foundation: ESIGN Act, UETA, and eIDAS
In the United States, the Electronic Signatures in Global and National Commerce (ESIGN) Act and the Uniform Electronic Transactions Act (UETA) establish a clear principle: a contract or signature cannot be denied legal effect or enforceability solely because it is in electronic form.
Similarly, in the European Union, the eIDAS regulation governs electronic transactions across all 27 member states, recognizing Simple Electronic Signatures (SES), Advanced Electronic Signatures (AES), and Qualified Electronic Signatures (QES).
- Intent to Sign: The signer must demonstrate clear voluntary intent to execute the document.
- Consent to Electronic Business: All parties must agree to conduct business electronically.
- Association of Signature: The signature must be logically associated or linked with the document stream.
- Document Integrity: The signed document must be tamper-evident and preserved in its final executed form.
#2Drawn, Typed, or Uploaded: Which Format Is Best?
Courts do not require a digital signature to replicate your physical handwriting. A typed name rendered in an italicized legal font, a vector-drawn signature created with a stylus or finger, or an uploaded scan of a physical signature are all legally valid, provided the signer's identity and intent are established.
The critical technical factor is immutability: after signing, the PDF must be flattened so the signature cannot be selected, copied, or repositioned by a malicious party.
#3How MistPDF Ensures Total Signature Privacy

Your drawn vector strokes, typed signatures, and contract terms never touch any remote cloud. You receive a finalized, flattened, tamper-evident contract with zero subscriptions, zero account creation, and zero privacy exposure.
