What Is AutoFillPDF?

AutoFillPDF is an AI-powered platform for filling PDF forms in seconds. It identifies form fields in any PDF, maps your data to those fields, and outputs a clean, filled document. This works on native fillable PDFs and on documents that were never designed to be fillable.

If you spend time copying data from spreadsheets or systems into PDFs, AutoFillPDF replaces that manual work with a repeatable, accurate workflow.

What Problems Does It Solve?

AutoFillPDF is built for teams that deal with high volumes of paperwork or time-sensitive documents. It removes the bottleneck of manual data entry and reduces errors that happen when people copy and paste.

Typical use cases include:

  • Client onboarding packets
  • Insurance and compliance forms
  • HR and employee paperwork
  • Real estate and lending documents
  • Government or medical intake forms

How AutoFillPDF Works

1) Upload or connect a PDF

Provide a PDF from your local files or by API. AutoFillPDF supports both fillable and non-fillable documents.

2) AI field detection

The system scans the PDF, detects fields, and classifies them (text inputs, checkboxes, dates, signatures, and tables).

3) Data mapping

You can map data from CSV, JSON, or your API payloads. The AI suggests matches and you can confirm or override mappings.

4) Fill and review

AutoFillPDF applies the data, formats it correctly, and generates a filled PDF. You can review, export, or automate the output.

Core Capabilities

  • Field detection on non-fillable PDFs
  • Bulk filling from CSV or structured JSON
  • API automation for high-volume workflows
  • Support for signatures, checkboxes, and tables
  • Consistent formatting across pages

Who AutoFillPDF Is For

AutoFillPDF is designed for operators, analysts, and engineering teams who need to produce accurate PDFs quickly. It works well for small teams that want to eliminate manual work and for enterprises that need repeatable document workflows.

Security And Data Handling

AutoFillPDF follows standard best practices for handling sensitive documents. Keep sensitive data in your own systems and send only what you need for the fill operation. For high-compliance environments, use the API to control data flow and retention policies.

Getting Started

  1. Open the AutoFillPDF dashboard.
  2. Upload a sample PDF.
  3. Map your data fields.
  4. Generate and export a filled document.

If you want to automate the process, use the API to programmatically upload PDFs and retrieve completed files.
