What is PDF SDK?

PDF SDKs (Software Development Kits) provide developers with the tools and libraries needed to integrate PDF functionality into their applications or websites. These SDKs offer features like viewing, editing, creating, converting, and annotating PDFs, allowing developers to build custom PDF solutions tailored to their needs. PDF SDKs often include APIs for manipulating text, images, and form data, as well as for handling document security, such as encryption and password protection. By using PDF SDKs, developers can add robust PDF capabilities to their software without having to build these features from scratch, saving time and resources. Compare and read user reviews of the best PDF SDK currently available using the table below. This list is updated regularly.

    FPDF

    FPDF

    FPDF

    FPDF is a solution written in PHP that allows you to generate PDF documents directly from PHP, so you can use the PDFlib library. The F of FPDF means free, so you can use it for any purpose and modify it to your liking to satisfy your needs. FPDF does not need any extension for PHP (except Zlib to enable compression and GD for GIF support) and works with PHP5 (≥ 5.1), PHP7 and PHP8. The tutorials will allow you to quickly access FPDF. FPDF generates documents in many other languages apart from the Western European ones, like Central, Cyrillic, Greek and Baltic, if they have TrueType or Type1 sources with the set of appropriate characters. UTF-8 is also available. The speed of generation of a document is less than that of PDFlib. Without the resentment, however, is very reasonable and is adequate for the majority of cases, unless its documents are specifically compiled or extended.

PDF SDK Guide

PDF SDK is a software development kit (SDK) designed to allow developers to generate, edit, and manipulate PDF documents. It provides a comprehensive set of APIs for developers to access, modify, and interact with the contents of PDF documents. The SDK contains powerful tools that enable developers to quickly develop applications that can reduce the complexity of creating and maintaining PDF files.

The SDK offers support for all sorts of features related to PDFs like adding annotations, stamps, highlighting content, generating thumbnails and page previews, extracting text from scanned documents, merging two or more PDFs into one document. It also covers support for interactive forms so users can fill out their information directly on the form without having to manually type it in. Moreover there are several advanced features like combining pages from multiple sources into one document as well as modifying document properties such as metadata or security settings.

Moreover the SDK allows you to dynamically add visual elements (text boxes, images etc.) by providing a simple API enabling you to easily create complex documents. Furthermore it provides an API that lets you perform various operations on existing PDF documents such as extracting text from them or splitting them into individual pages based on certain criteria. This makes it easy for developers who need to work with large amounts of data quickly. Additionally, it includes an API which enables you to perform OCR (optical character recognition) on scanned materials allowing them to be used within your applications without any manual intervention required by the user.

By using this powerful toolkit developers can quickly create enterprise-level applications that require high-end PDF processing capabilities such as automated document generation systems or workflow solutions requiring complex manipulation of existing documents in order to produce modified versions according to requirements without sacrificing quality standards or security measures needed in businesses today.

The components which form part of this kit are fully cross-platform compatible making it easier for developers working in different platforms such as Windows and Linux operating systems alike while also offering integration with other third party solutions via its API layer providing great flexibility in terms of what options are available when building sophisticated solutions leveraging the power offered by this SDK package.

The PDF SDK is an invaluable tool that provides businesses with the flexibility and control they need to create powerful PDF-based applications without compromising on quality or security standards. It is constantly being updated, thus making sure that developers always have access to the latest features and APIs as soon as they are released.

Features Offered by PDF SDK

  • Annotation Support: Allows users to view, create, edit, and save annotations such as notes, highlights, freehand drawings, shapes, and more on the PDF documents.
  • Form Filling: Enables users to fill out interactive PDF forms quickly and accurately with custom data fields. These forms can then be saved for later use or for easily submitting information to other applications.
  • Document Security: Offers encryption features like digital signatures and password protection to help keep sensitive documents secure.
  • Image Conversion: Supports conversion between PDFs and common image formats like JPG, PNG, GIF, etc., allowing users to transform single-page PDFs into multiple images or vice versa depending on their needs.
  • Merge & Split Documents: Provides tools for merging multiple documents into one or splitting larger files into smaller chunks that are easier to manage or transfer.
  • Text Extraction & Searching Capabilities: Allows users to extract text from PDFs and search through it using keywords without needing to open the document in an external editor first. This is especially useful for quickly finding specific phrases or terms within a large number of documents.
  • Document Optimization & Compression: Provides options for reducing file size by optimizing and compressing the PDFs so that they can be more easily shared and stored.
  • OCR (Optical Character Recognition): Allows users to convert scanned PDF documents into searchable and editable files, making them much easier to work with.

Different Types of PDF SDK

  • Portable Document Format (PDF) SDKs: These SDKs provide access to the features of PDF documents including document manipulation, content extraction, form filling and other functions. They allow for integration with other applications for creating, editing, merging, signing and protecting PDF documents.
  • Image-Based PDF SDKs: These are used to convert scanned images into searchable and electronically processable PDF files. They provide improved accuracy in text recognition from images due to advanced OCR technology.
  • Text-Based PDF SDKs: These allow developers to work with text data stored in a PDF file without the need for manual conversion into another format such as HTML or XML. This type of SDK allows for seamless integration into web applications and automated processes that require extracting content from raw data stored in a PDF file.
  • Conversion-Type PDF SDKs: These enable developers to convert data within a document between different formats (e.g., HTML, Word or Excel). This type of SDK is useful when there is a need to integrate with legacy systems or external APIs which require processing of documents within their native format such as Word or Excel documents.
  • Interactive Form Filling / Signing SDKs: These offer features related to interactive forms such as filling them out, adding signatures and more. They can also track user activity on the forms and generate reports based on this activity which makes them very useful in terms of managing online contract signings or any other process requiring an interactive form component.
  • Document Security SDKs: These are used to add watermarks, encrypt and digitally sign documents. They are useful for protecting confidential documents from unauthorized access or alteration.
