What is an electronic signature solution?
An electronic signature solution is software that lets you sign documents and collect legally binding signatures online, without printing or scanning. QuickSigner is a cloud-based electronic signature solution that adds certificate-based signatures (PAdES on the Adobe Approved Trust List) to your PDFs and Word files, with ISO/IEC 27001 security and legal recognition across the US, UK, and EU.
Is signing documents and agreements through QuickSigner.com legally binding?
Documents and agreements eSigned with QuickSigner are legally binding and recognized in the UK, USA, and all EU member states — under the US ESIGN Act and UETA, UK law, and EU eIDAS. QuickSigner uses the PAdES standard for Advanced Electronic Signatures, with a full audit trail (signer identity, IP, timestamps) and tamper-proof protection, so a signed document cannot be altered.
How do I sign a PDF online for free?
Upload your PDF to QuickSigner, drag and drop your signature where it belongs, then download or send the signed file — all in under a minute. Your first PDF is free, with no credit card required. You can draw, type, or upload your signature, all from your browser with no software to install.
What is the difference between an electronic signature and a digital signature?
An electronic signature is any electronic way of showing agreement to a document — typing your name, drawing it, or clicking to sign. A digital signature is a specific, more secure type of electronic signature that uses cryptographic certificates to verify the signer and protect the document from tampering. Every digital signature is electronic, but not every electronic signature is digital. QuickSigner gives you both: a simple signing experience backed by certificate-based PAdES digital signatures, so your documents are easy to sign and hold up to scrutiny.
What is a certificate-based eSignature?
A certificate-based eSignature seals your document with a cryptographic digital certificate rather than just an image of a signature. QuickSigner uses the PAdES standard on the Adobe Approved Trust List (AATL), so every signed PDF carries a verifiable certificate, a full audit trail, and tamper-proof protection — recognized across the US, UK, and EU.
How much does QuickSigner cost?
QuickSigner is free to start. Paid plans are $5/user/month (Business) and $15/user/month (Professional), with 20% off when billed annually. The eSign API is usage-based from $0.30 per signed document, with free credits included — and there are no envelope caps and no per-seat lock-in.
Is QuickSigner a good DocuSign alternative?
Yes. QuickSigner is a cost-effective DocuSign alternative with no per-seat lock-in and no envelope caps — paid plans from $5/user/month, or a usage-based API from $0.30 per signed document, with the same AATL and ISO/IEC 27001 security. See our DocuSign alternatives guide for a full comparison.
Can I send a document to someone else to sign?
Yes. Add one or more signers and send a secure signing link — recipients sign from any device with no account, no app, and no token required. You can set a signing order and track progress in real time.
Do I need a token with a digital certificate?
No. To sign documents with QuickSigner.com, signatories DO NOT need a token or other forms of digital certificate.
All that’s required is internet access and an email address where the signatory can receive the secure link to the document to be signed.
