Extract Text from PDF Document with Java REST API

This concise guide shows you how to extract text from a PDF document using the Java REST API. Leveraging the Java Cloud SDK, you’ll learn to pull text from PDFs with a Java‑based API and display it, complete with sample code that walks you through the entire process.

Prerequisite

Steps to Extract PDF Text with Java Low Code API

  1. Configure the PdfApi by providing the application key and SID to read the PDF file
  2. Upload the source PDF file for extracting the text
  3. Call the GetText() method upon successful uploading of the source PDF file
  4. Set the rectangular area of the page from which text is to be fetched on all the pages
  5. Parse through all the occurrences of the text in the API response and display the text

These steps entail the process to read PDF text with Java RESTful Service. Load the PDF file into the Cloud storage and call the GetText() method to fetch all occurrences of the text from all the pages in the loaded PDF file from the specified rectangle on the page. Praise through all the occurrences in the response and display page number and text.

Code to Grab Text from PDF with Java REST Interface

This example illustrates how to retrieve text from PDF with Java REST Interface. Define the rectangular region by its lower‑left (x, y) and upper‑right (x, y) coordinates to specify where the text should be extracted. If you only need text from a single page, call the GetPageText() method and provide the page number as an additional argument.

In this guide we showed how to extract text from a PDF using a Java REST API—no external PDF reader needed. If you’d like to take the next step and count the words in a PDF, see our article on Count words in PDF document with Java REST API.
