This page serves as a guide for using the Pdfcrowd API to convert PDF to HTML via HTTP POST. The API is HTTP-based and communicates through standard HTTP requests. You can call the API by sending an HTTP request to the API server address with options passed as POST data.
You can also check out our API client libraries if you want to implement the API in your favorite programming language.
Below are HTTP POST examples to help you quickly get started with the API. Explore our additional examples for more insights.
To access the API, you will need to use your Pdfcrowd username and API key. For initial testing, you may use the following demo credentials without registering:
