Save Byte Array to PDF C# (Code Example)

A PDF file is essentially a high-resolution image of a word processing document. It is formatted according to the page size, font, and other application characteristics that created it. Due to its cross-platform compatibility, PDF has become an essential way for enterprises to transport documents securely.

The PDF is searchable, editable even across geographical boundaries, can be sent electronically, and reduces translation costs by combining content in a single document. No plugin or reader is required — the content in one client’s language is rendered and edited in another, regardless of the device used (laptop, tablet, or smartphone). We can scan multi-page documents using the flatbed scanner glass or automatic document feeder.

PDF files are cross-compatible on most technology devices: laptops, desktop computers, tablets, and smartphones; plus, they are done before being sent automatically, thereby reducing translation costs. PDF files also offer greater flexibility than other formats for viewing, as many people can view them at once. In this article, we will explore multiple methods for scanning multiple pages into one PDF file.

The Adobe Scanner APP

PDFs can be scanned on the go and are accessible at any time. PDFs are readily available and shareable. They provide a digital record of documents that is more accurate than a screen capture or printout copy.

PDFs also keep form fields, such as text fields, buttons, checkboxes, and radio buttons intact. Scanning documents to PDF files is useful when you need to share them with someone else who doesn't have access to the document's physical copy.

We will use a mobile application for scanning multiple pages into one PDF file using the scan tab. The mobile application is the Adobe Scanner App. You can download it from the Play Store for Android phones or the Apple store for iPhones. You can also download it from the Adobe Acrobat website.

You can take snaps of multiple pages of scanned files, PDF documents, multiple scanned pages, or scanned images and convert them into a single PDF file. You can see everything in the "scan preview" window. You can upload scan documents to the cloud using this application. It can detect sharp borders and content areas, and then create a shareable and editable PDF file.

Scan Pages from Adobe Acrobat

Adobe Acrobat is a desktop application for creating, editing, signing, and printing PDF files. It can be used to convert any electronic document into a PDF file. With the help of this program, you can edit and annotate your PDFs. You can also access all the features on a mobile device.

The Acrobat software has a wide range of features and uses. It is capable of merging PDF documents, converting images into PDF files, creating fillable forms, and much more. The software can also be used for editing scanned copies or files in JPEG format.

Let's examine how we can make a PDF file by scanning multiple pages using Adobe Acrobat:

Step 1

Open Adobe Acrobat Pro on your desktop.

Step 2

Go to the tools.

Step 3

Click on the Create option.

Step 4

Click on the Scanner.

Step 5

Select any available scanner.

Step 6

Select pre-defined scan settings according to your requirements.

Step 7

Click on the Scan button.

Conclusion

By following the above procedure you will be able to scan all the pages and convert them into one PDF file. You may prefer scanning multiple pages so that the resultant PDF files will be more comprehensive and contain more data.

IronPDF: C# PDF Library

IronPDF is a C# PDF library for creating and editing PDFs on Windows. It was created by .NET developers who wanted to have the same functionality as Adobe Acrobat but in a more simplified way. IronPDF is an easy-to-use and lightweight library with many features that we can use programmatically:

  • Supports conversion of images, text, and inline graphics to PDF

  • Edit pages with text, shapes, and line drawings

  • Convert between PDF formats

  • Create password-protected or watermarked documents

IronPDF is a library of C# PDF API features. It provides the developer with easy-to-use tools for creating, editing, encrypting, and signing PDF documents from within .NET applications based on Microsoft .NET Framework 4 or later.

The IronPDF library is written entirely in C# to provide an easy way for .NET developers to write PDF documents. The goal of the IronPDF library is to provide a set of API calls that make it simple for developers to create PDFs, apply digital signatures, and encrypt their information.

IronPDF enables developers to write very efficiently and with fewer lines of code for PDF processors. Let's take a look at how we can scan multiple pages or images into one PDF using IronPDF.

// PM> Install-Package IronPdf
using IronPdf;
using System.IO;
using System.Linq;

// One or more images as IEnumerable. This example selects all JPEG images in a specific 'assets' folder.
var ImageFiles = System.IO.Directory.EnumerateFiles("assets").Where(f => f.EndsWith(".jpg") || f.EndsWith(".jpeg"));

// Converts the images to a PDF and saves it.
ImageToPdfConverter.ImageToPdf(ImageFiles).SaveAs("composite.pdf");
// PM> Install-Package IronPdf
using IronPdf;
using System.IO;
using System.Linq;

// One or more images as IEnumerable. This example selects all JPEG images in a specific 'assets' folder.
var ImageFiles = System.IO.Directory.EnumerateFiles("assets").Where(f => f.EndsWith(".jpg") || f.EndsWith(".jpeg"));

// Converts the images to a PDF and saves it.
ImageToPdfConverter.ImageToPdf(ImageFiles).SaveAs("composite.pdf");
' PM> Install-Package IronPdf
Imports IronPdf
Imports System.IO
Imports System.Linq

' One or more images as IEnumerable. This example selects all JPEG images in a specific 'assets' folder.
Private ImageFiles = System.IO.Directory.EnumerateFiles("assets").Where(Function(f) f.EndsWith(".jpg") OrElse f.EndsWith(".jpeg"))

' Converts the images to a PDF and saves it.
ImageToPdfConverter.ImageToPdf(ImageFiles).SaveAs("composite.pdf")
VB   C#

In the code above, we use the ImageToPdf function of IronPDF to scan a bunch of images from the system and convert them to a PDF file. We use the IO.Directory.EnumrateFiles to fetch images from the system. For more tutorials, please visit the following link.
