Two Ways to Capture Signatures

Draw Signature

Recipients can draw their signature directly on the form using a mouse, trackpad, or touch screen. Perfect for mobile devices and tablets, and convenient for desktop users.

  • • Touch-friendly drawing canvas
  • • Works on all devices (desktop, tablet, mobile)
  • • Clear and redraw options
  • • Smooth signature capture

Upload Signature Image

Users can upload a pre-existing signature image file (PNG, JPG, etc.). Ideal for users who prefer to use a scanned signature or have a saved signature file.

  • • Upload from device storage
  • • Supports common image formats
  • • Automatic sizing and positioning
  • • Perfect for users with signature files

Multi-Page Signature Support

FileThis.io supports adding the same signature field to multiple pages of your form. This is essential for complex contracts, multi-page agreements, and documents that require signatures at specific points throughout the document.

Each signature instance is tracked independently, so recipients can sign each occurrence separately. This is perfect for:

  • Contracts requiring signatures on multiple pages
  • Legal documents with section-specific signatures
  • Multi-party agreements where each party signs specific sections
  • Forms with acknowledgments at different points in the document

Signature and Initial Fields

FileThis.io supports two types of signature fields, giving you flexibility in how you design your forms:

Signature Fields

Full-size signature fields for formal signatures. Perfect for contracts, agreements, and any document requiring a complete signature.

Use for: Contracts, agreements, authorizations, approvals, legal documents

Initial Fields

Smaller signature fields for initials. Ideal for acknowledging specific sections, changes, or terms within a document.

Use for: Section acknowledgments, change approvals, term confirmations, minor updates

Legal Compliance & Audit Trail

FileThis.io provides a comprehensive audit trail for all signatures, ensuring legal compliance and accountability:

What's Recorded

  • Signature image (drawn or uploaded)
  • Timestamp of when signature was captured
  • User identity (profile ID or guest UUID)
  • IP address and user agent
  • Field UUID and instance ID for tracking
  • Immutable form snapshot at time of signature

Legal Note: FileThis.io provides simple e-signature capabilities with consent checkboxes and comprehensive audit trails. For documents requiring advanced e-signature compliance (e.g., ESIGN Act, eIDAS), consult with legal counsel to ensure FileThis.io meets your specific regulatory requirements.

Rich Text Labels & Customization

All signature and initial fields support rich text labels, allowing you to format labels exactly as needed:

  • Format label text with bold, italic, underline, and strikethrough
  • Customize text and background colors
  • Adjust font size for emphasis
  • Mark fields as required or optional

This flexibility allows you to create professional signature blocks that match your document's style and legal requirements.
