URL-Based Input (Publicly Accessible Files)

The API Tester works best with publicly accessible file URLs as the input source. This means:

  • your file must be reachable via a public link (e.g., file hosted on cloud storage)
  • the API can download and process the file directly

This makes testing simpler and faster without requiring manual uploads inside the tester.

Access to Advanced Features

The API Tester supports advanced settings depending on the endpoint. For example, you can modify parameters such as:

  • profiles (for OCR settings, filters, and processing behavior)
  • async
  • output types and configuration options

This makes it easier to test different scenarios and fine-tune your results.

Summary

The PDF.co API Tester is an efficient way to explore and test PDF.co Web API endpoints. It helps you validate your requests quickly, review outputs instantly, and experiment with advanced settings before implementing the API in your workflow.
