Server PDF Library Comparison (Free & Paid Tools)

When talking about servers in regards to PDFs, they represent a module or system that specifically offers PDF document handling and management on the server. Applications can, therefore, create, process, and deliver PDF files on the server without any intervention from the client. In fact, this technology is part of an essential set of many web-based applications, enterprise systems, and cloud services that depend on the automated processing of PDFs without requiring human intervention.

Normally, a server-side PDF solution generates PDFs on the fly, for instance, by generating reports, invoices, or other documents from templates, user input, or data from databases. It also supports various manipulative aspects of existing PDFs, such as merging many PDFs into one, splitting a single PDF into many separate files, adding watermarks, or extracting just certain pages.

Server-side PDF generation offers enhanced security by keeping sensitive data on the server, reducing the risk of exposure during creation. In contrast, Java apps using a Java library for PDF generation can pose security risks, primarily if the PDF is generated on the client side or within an unsecured environment. With a Java PDF library, sensitive information could be exposed on the user’s device or during transmission, making it harder to enforce strict security measures.

On the other hand, server-side solutions provide better centralization and monitoring, which can be crucial for maintaining data integrity. Key benefits of server PDFs are that they can support and create highly scalable solutions for high-performance, high-throughput document processing, and also reliably handle demanding environments. PDF solutions have been widely used within vertical industries such as finance, healthcare, and e-commerce, whereby security, consistency, and automation of PDF document processing are crucial to business operations.

formio/pdf-server

formio/pdf-server is a server-side solution that extends the capability of the Form.io platform with dynamic document and PDF management and generation. At the core of the functionality, Form.io is an extremely capable platform for form-based application development with a huge set of features offered for form creation, administration, and processing.

The PDF-server component fulfills this by providing the capability to auto-generate PDFs based on form data; it can be argued that it's a vital component for applications whose requirements call for the generation of PDF documents, output-report generation, invoicing, and document archiving.

Formio/pdf-server could be used to further process the form submissions into a fully formatted PDF document and will include metadata about the structure and data captured in forms. Sometimes in a scenario, users need to download or email forms completed as PDFs, and the system will store an uneditable permanent record of the data for that form.

Formio/pdf-server is a server-side renderer, so it can efficiently handle a large volume of requests. Applications requiring enterprise-level scalability and reliability can be effectively handled. It will also integrate seamlessly with Form.io's existing workflow so that developers can easily set up PDF document generation as part of their form-processing logic.

a0ne/docker-pdf-server

a0ne/docker-pdf-server is a Docker-based solution to generate and process PDF documents in containerized environments. Docker is an open platform for packaging an application and its dependencies into a container for predictable and reliable production, development, and deployment, with no more painful deployments. And that's exactly what a0ne/docker-pdf-server does: it offers a ready-to-use, scalable, and efficient way of performing server-side operations on PDFs.

It is based on the Docker image used heavily in the automation of creating, manipulating, and converting PDFs.

    var result = await client.EncryptAsync(pdfFilePath: "Demo.pdf", newOwnerPassword: "owner password here", newUserPassword: "user password here");

    // Write the encrypted result to a new file on the local file system
    File.WriteAllBytes("EncryptedFile.pdf", result);
}

// Indicate the completion of the file processing on the console
Console.WriteLine("File Process completed");

// Wait for any key press to keep the console open preventing an instant exit
Console.ReadKey();

// Import the IronSecureDoc namespace to access its functionalities
using IronSecureDoc;

// Indicate the start of the file processing on the console
Console.WriteLine("File Process started");

// Create a new client instance to connect to the IronSecureDoc server
var client = new IronSecureDocClient("http://localhost:8080");

// Try connecting to the IronSecureDoc server asynchronously
if (await client.TryConnectAsync())
{
    // Encrypt the specified PDF file with the provided owner and user passwords
    var result = await client.EncryptAsync(pdfFilePath: "Demo.pdf", newOwnerPassword: "owner password here", newUserPassword: "user password here");

    // Write the encrypted result to a new file on the local file system
    File.WriteAllBytes("EncryptedFile.pdf", result);
}

// Indicate the completion of the file processing on the console
Console.WriteLine("File Process completed");

// Wait for any key press to keep the console open preventing an instant exit
Console.ReadKey();

' Import the IronSecureDoc namespace to access its functionalities
Imports IronSecureDoc

' Indicate the start of the file processing on the console
Console.WriteLine("File Process started")

' Create a new client instance to connect to the IronSecureDoc server
Dim client = New IronSecureDocClient("http://localhost:8080")

' Try connecting to the IronSecureDoc server asynchronously
If Await client.TryConnectAsync() Then
	' Encrypt the specified PDF file with the provided owner and user passwords
	Dim result = Await client.EncryptAsync(pdfFilePath:= "Demo.pdf", newOwnerPassword:= "owner password here", newUserPassword:= "user password here")

	' Write the encrypted result to a new file on the local file system
	File.WriteAllBytes("EncryptedFile.pdf", result)
End If

' Indicate the completion of the file processing on the console
Console.WriteLine("File Process completed")

' Wait for any key press to keep the console open preventing an instant exit
Console.ReadKey()

This C# code snippet initiates a process for encrypting a PDF file using the IronSecureDoc service. First, on the console, it prints "File Process started," indicating the beginning of the process.

An instance of the IronSecureDocClient is created and initialized to connect to the IronSecureDoc server running at http://localhost:8080. It will then check if it has successfully connected to the server using the asynchronous TryConnectAsync method. If connected, it will call the asynchronous EncryptAsync method.

This method will take the PDF file "Demo.pdf" and encrypt it with the given owner and user passwords, then save the encrypted PDF as "EncryptedFile.pdf" on the local file system. Once the encryption process is finished, it prints "File Process completed" on the console and then waits for any key press to exit the program. This gives the user a chance to view the output files.
