Drag fields onto a fixed PDF.
Ship a fillable API in minutes.
Upload your invoice, COI, Form 16, W-9, or any DOCX. Place 30+ field types with pixel-precise rectangles. Mezdoc returns a filled PDF for every API submission - versioned, audited, traceable.
Built for paperwork that runs in production.
Drag-to-draw fields
Hold and drag on any page to draw a rectangle. Mezdoc creates a field at that position, with smart snapping and 8-handle resize.
Aliased linking
Same value, multiple pages. Type the field once on page 1 and link it to pages 3, 7, and 12 - every render stays in sync.
Versioning + environments
Save versions, promote between staging and production, rollback any time. Every submission records the exact version it ran on.
Native eSignature
Place a signature field. Send signers via email, SMS, or WhatsApp. Aadhaar eSign (IN) and ESIGN Act (US) both supported.
Calculated fields
Reference other fields with {{alias}}. Mezdoc computes totals, subtotals, GST, taxes - all at render time.
Conditional visibility
Hide or show fields based on submission data. The same template adapts to corporate, individual, or NGO billing.
Test renders
Hit 'Test PDF' in the editor. Mezdoc renders a real PDF in under two seconds with your dummy data.
Audit trail
Every submission records who submitted it, from where, against which version, with which IP - and what the resulting PDF was.
Webhook events
submission.created · submission.completed · pdf.generated. Signed with HMAC, delivered with retries.
Every field you'll ever need. And then some.
Each type comes with sensible validation, formatting, and a sensible preview. India and US identifiers are first-class.
