Illustration: How to Delete PDF Pages Using PHP

In this post, you’ll learn how to delete PDF pages using our Delete PDF Page PHP API. With our API, you can process up to 100 PDF files per month for free. You’ll just need to create a free account to access your API key.

This post will be especially helpful for developers working with PHP in document-heavy workflows who need to programmatically remove pages from a PDF to delete confidential data, save storage space, or remove information that’s unnecessary for end users.


Deleting PDF pages is just one of the operations possible with our 30+ PDF API tools. You can combine our deletion tool with other tools to create complex document processing workflows, such as:

  • Converting MS Office files and images into PDFs before removing pages

  • Removing pages from two documents before merging them

  • Deleting pages and then watermarking and flattening PDFs

Once you create your account, you’ll be able to access all our PDF API tools.

Step 1 — Creating a Free Account on PSPDFKit

Go to our website, where you’ll see the page below, prompting you to create your free account.

As you can see in the bottom-left corner, you’ll start with 100 documents to process, and you’ll be able to access all our PDF API tools.

Step 2 — Obtaining the API Key

After you’ve verified your email, you can get your API key from the dashboard. In the menu on the left, click API Keys. You’ll see the following page, which is an overview of your keys:

Copy the Live API Key, because you’ll need this for the Delete PDF Page API.

Step 3 — Setting Up Folders and Files

Now, create a folder called delete_pdf and open it in a code editor. For this tutorial, you’ll use VS Code as your primary code editor. Next, create two folders inside delete_pdf and name them input_documents and processed_documents.

Then, in the root folder, delete_pdf, create a file called processor.php. This is the file where you’ll keep your code.

Your folder structure will look like this:

├── input_documents
├── processed_documents
└── processor.php

Step 4 — Writing the Code

Open the processor.php file and paste the code below into it:


$FileHandle = fopen('processed_documents/result_php.pdf', 'w+');

$curl = curl_init();

$instructions = '{
  "parts": [
      "file": "document",
      "pages": {
        "end": 2
      "file": "document",
      "pages": {
        "start": 4

curl_setopt_array($curl, array(
  CURLOPT_URL => '',
    'instructions' => $instructions,
    'document' => new CURLFILE('input_documents/document.pdf')
    'Authorization: Bearer YOUR_API_TOKEN'
  CURLOPT_FILE => $FileHandle,

$response = curl_exec($curl);



ℹ️ Note: Make sure to replace YOUR_API_TOKEN with your API key.

Code Explanation

The “instructions” part of the code above specifies that page 4 should be deleted.

You then make the API call using the CURL library. Once you receive the API response (the PDF with a deleted page), it’s stored in the file in the processed_documents folder.


To execute the code, run the command below:

php processor.php

On successful execution, you’ll see a new processed file, result_php.pdf, located in the processed_documents folder.

The folder structure will look like this:

├── input_documents
|    └── document.pdf
├── processed_documents
|    └── result_php.pdf
└── processor.php
