Everything you need to know about digital document signing
PDF signing is the process of adding a digital signature to a Portable Document Format (PDF) file to authenticate the identity of the signer and ensure the document's integrity. Digital signatures serve as the electronic equivalent of handwritten signatures, providing a secure and legally binding way to sign documents without the need for printing and physical signing.
Modern PDF signing technology uses cryptographic techniques to create a unique digital fingerprint of the document. This ensures that any changes made to the document after signing will invalidate the signature, providing tamper-evidence and document authenticity. Whether you're signing contracts, agreements, invoices, or any other important documents, PDF signing offers a convenient, secure, and environmentally friendly alternative to traditional paper-based signing methods.
Digital signatures come in various forms, each serving different purposes and offering different levels of security. Understanding these types will help you choose the right signature method for your needs:
The most basic form, including typed names, uploaded images, or drawn signatures. Suitable for low-risk documents and internal approvals.
More secure, uniquely linked to the signer and capable of identifying them. Often require additional authentication methods.
The highest level of security, created using a qualified digital certificate. Equivalent to handwritten signatures across the EU.
Use PKI (Public Key Infrastructure) technology to provide the highest level of security and non-repudiation.
Digital signatures are legally recognized in most countries worldwide, with specific laws and regulations governing their use. Understanding the legal framework ensures your signed documents hold up in legal proceedings:
For high-value contracts or legally sensitive documents, consider using advanced or qualified electronic signatures to ensure maximum legal enforceability.
Follow these best practices to ensure your PDF signatures are secure, professional, and legally compliant:
PDF signing has revolutionized how businesses and individuals handle document workflows. Here are the most common applications:
Sales contracts, service agreements, partnership deals, and vendor contracts can be signed digitally, reducing turnaround time from days to minutes.
Employment contracts, offer letters, NDAs, policy acknowledgments, and performance reviews can be processed entirely digitally.
Invoices, purchase orders, loan applications, tax forms, and financial reports can be signed and processed quickly.
Student enrollments, transcript requests, diploma certifications, and academic approvals can be handled digitally.
Patient consent forms, medical records authorizations, insurance claims, and treatment agreements can be signed securely.
Security is paramount when dealing with digital signatures and sensitive documents. Here are essential security measures to implement:
Always use end-to-end encryption for document transmission. Implement password protection for sensitive PDFs and consider adding watermarks for additional security.
Implement multi-factor authentication for high-value documents. Use email verification, SMS codes, or biometric authentication to verify signer identity.
Maintain comprehensive audit trails documenting who signed what, when, and from where. This provides legal evidence and helps resolve disputes.
Properly manage digital certificates, including issuance, renewal, and revocation. Use certificate authorities recognized in your jurisdiction.

Everything you need to know about PDF signing
Yes, digitally signed PDF documents are legally binding in most countries. In the United States, the eSign Act gives electronic signatures the same legal weight as handwritten signatures. Similar laws exist in the EU (eIDAS), Canada, Australia, and many other countries. However, for certain high-value documents, you may need advanced or qualified electronic signatures.
Our PDF signing process uses 256-bit SSL encryption to secure your documents during transmission. We never store your files on our servers - all processing happens in your browser. The signatures are cryptographically bound to the document, making any tampering evident. For additional security, we recommend using password protection and keeping your signing certificates secure.
Yes, you can sign multiple pages in a PDF document. You can place your signature on any page, and even add different signatures or initials on different pages. The tool allows you to navigate through pages and place signatures exactly where you need them.
We primarily support PDF files for direct signing. However, you can also upload DOC, DOCX, XLS, XLSX, PPT, and PPTX files, which will be automatically converted to PDF format before signing. The final downloaded document will always be in PDF format to ensure compatibility and security.
Yes, multiple people can sign the same document. Each signature is independently validated and recorded in the document's signature panel. The tool maintains a clear audit trail showing who signed when and in what order, making it perfect for contracts and agreements requiring multiple signatories.
The free version supports PDF files up to 10MB in size. For larger files, you may need to compress the PDF first or upgrade to a premium plan. Most standard documents, including contracts and agreements, are well within this limit.
