Document eSign: Free Electronic Signature Platform with Digital Certificate Signing

• Draw, Type, or Upload Signatures: Signers choose their preferred method, whether drawing freehand on a touchscreen, typing their name to generate a signature, or uploading an existing signature image.
• Multi-Document Support: Bundle multiple documents into a single signing session. Recipients review and sign all documents in one flow instead of handling each file separately.
• Digital Signing with Trusted Certificates: Java Spring Boot-powered digital signature engine applies trusted certificates to documents, producing signatures that meet legal and regulatory standards for industries like real estate, finance, and government.
• REST API Integration: A comprehensive API that lets businesses embed signature requests directly into their applications, automating document generation, sending, and status tracking programmatically.
• Legally Binding E-Signatures: Every signature captured through the platform is legally binding and compliant with e-signature laws, backed by a complete audit trail that records signer identity, timestamps, and IP addresses.
• Reusable Templates: Create templates with predefined signer placeholders, signing order, and field positions. Use them repeatedly for recurring document types like NDAs, proposals, and asset handover forms.
• Real-Time Notifications: Signers and senders receive instant notifications at every step, from document delivery to signature completion, keeping all parties informed without manual follow-ups.
• Any-Device Signing: Responsive design ensures a consistent signing experience across desktops, tablets, and smartphones, so recipients can sign from wherever they are.
• Audit Trail and Document Security: Every document carries a tamper-evident audit log recording each action taken, providing a verifiable chain of custody for legal and compliance purposes.
• Two-Factor Authentication: Account security with two-factor authentication to protect documents and signing workflows from unauthorized access.
