About this tool

PDFGate is an API platform for document generation, processing, and electronic signatures, enabling PDF generation, signature collection, and document management through a simple dashboard or a flexible API.

Key capabilities

  • PDF API suite: The HTML to PDF API can convert HTML and URLs to PDF; the Extract PDF Form Data API can extract data from PDFs; the Watermark PDF API can add custom watermarks; the Protect PDF API can password-protect PDFs; the Compress PDF API can reduce file size without loss of quality; the Flatten PDF API can flatten forms to make them permanently fixed; the Digital Signature API can send documents for signing.
  • Electronic signatures: Provides legally binding electronic signatures, recording each signature and the signer's consent and activity. Recipients are verified via a one-time verification code sent to their email before they can access the document. Completed documents are digitally sealed, and any changes after signing can be detected. The system records every action, timestamp, and recipient event from sending to completion, forming a detailed audit trail.
  • Document workflow automation: Reusable templates avoid repeatedly preparing the same documents; automatic reminders help drive document flow; documents that are still in progress, expired, or need follow-up can be quickly identified; completed documents, recipient activity, and audit records can be found at any time.

How to use

  • Integrate via REST API, with a complete official REST API reference available.
  • Multiple SDKs are available: NodeJS, Java, C#, PHP, and Python client libraries.
  • An online web app can also be used to centrally manage documents, templates, signature activities, and completion records.
  • It can connect to existing systems and integrate with the tools and AI assistants the team already uses, adding PDF generation, electronic signatures, status tracking, and document processing capabilities directly in the application.

Use cases

  • Real estate: Manage property agreements, disclosure documents, lease documents, and multi-signer signatures.
  • Human resources: Turn repetitive recruiting and onboarding paperwork into reusable workflows, so new employees can complete it without printing or scanning.
  • Financial services: Send customer authorizations, disclosure documents, and agreements for signing, while clearly tracking recipient progress and completion records.
  • Legal and professional services: Manage powers of attorney, service agreements, and other client documents, covering the entire process from initial preparation to signing and final archiving.
