Introduction

Welcome to the Avanquest PDF API!

A modern, intuitive and simple REST‑based Web API that is as easy to use as 1‑2‑3.
No, really!

We love PDF and have coded the functionalities associated with it, so you don’t have to. This way you can concentrate on what you do best and let us do the heavy lifting.

Our application empowers developers with a suite of robust tools for seamless PDF processing and manipulation.
With a range of versatile services, you can streamline your document workflows and enhance productivity effortlessly.

We provide an extensive list of services all centered around PDF processing:

  • Convert PDF to Microsoft Office Word, Excel or PowerPoint
  • Merge multiple PDF files into a single PDF file, selectively choose specific pages or a range of pages from PDF files and combine them into one PDF file. It’s like writing your own PDF symphony!
  • Compress the size of PDF files to reduce your storage footprint
  • Split a PDF file into multiple PDF files. Think of it as unbinding a book and putting together its pages in any order you like.
  • Convert any HTML content to PDF – code, documents and websites. Bring them on!
  • Convert images to PDF – a PDF is now also worth a thousand words
  • TXT to PDF – convert multiple text formats into PDF
  • PDF to TXT – extract text content from PDF files
  • Delete Pages – erase unwanted or outdated pages or entire sections of a PDF
  • Rotate Pages within a PDF to get the orientation you want
  • Protect PDF by adding a password to restrict access to sensitive information
  • Resize PDF files to integrate into your custom application
  • Unlock PDF files by removing the password‑based security

All requests are securely served only through **https** and contain the base URL: **api-developers.avanquest.com**

Each one of our services is associated with a dedicated endpoint where you submit your files for processing via a POST request. For details about each individual endpoint, you can refer to the specific service you are interested in.

We don’t keep your information. We only store your files for the purpose of processing your requests. The results will be available for a time limit of 10 minutes, after which your data will automatically be discarded.

Our API utilizes Asynchronous Mode of operation as it is superior to Synchronous Mode in the aspects that matter for a PDF API in more than one way:

  • You instantly get a response – our server assigns an **operationId** to your request and goes off to process it in the background.
  • No time‑outs – ideal for handling computationally intensive tasks which would potentially time out if using Synchronous mode.
  • Visibility – find out the state of the operation by polling the **/status endpoint.
  • Scalability and efficiency – allows our servers to handle more of your requests when you are running them concurrently.
  • Better user experience for you – it allows the client to continue with other tasks while waiting for the result.
  • More flexibility in handling varied client requirements and workloads.
