This page describes how to use our cloud-based API to convert PDF to HTML in Golang. The API is user-friendly and can be integrated into your application with just a few lines of code.
The Golang API client library provides easy access to the Pdfcrowd API. No third-party libraries are required.
Install the client library from Githubgo get github.com/pdfcrowd/pdfcrowd-go
We also offer other installation options.
The credentials to access the API are your Pdfcrowd username and the API key. You can try out the API without registering using the following demo credentials:

To get your personal API credentials, you can start a free API trial or buy the API license.
Refer to the PDF to HTML Golang Reference for a description of all API methods.
Here are a few Golang examples to get you started quickly with the API. See more examples.
