PDF SDK Libraries
With just a few lines of code, LEADTOOLS libraries empower developers with a comprehensive PDF API to implement reliable and multi-threaded PDF functionality, without the need for third-party dependencies like Acrobat. Robust PDF controls to read, write, convert, and view PDF files can be combined with state-of-the-art OCR, ICR, OMR, Forms Recognition, Virtual Printing, and scanning APIs within LEADTOOLS to create complete solutions that utilize the PDF format.
Robust PDF Viewer Controls
Load and view any PDF file using the Document Viewer API framework. Tested against thousands of PDF documents, LEADTOOLS PDF SDK libraries provides impeccable viewing accuracy and speed that tops many market-leading PDF reading applications. LEADTOOLS accounts for common errors and differences between PDF file versions to give programmers peace of mind, minimize their testing phase, and create the best PDF applications faster.
Complete PDF Conversion API
The LEADTOOLS Document Converter API can perform any type of conversion to and from PDF. For example, convert to and from PDF: PDF/A, other document and Office formats, images, HTML, EMF, and SVG. There are more than 150 file types are supported. The Document Converter API is flexible and gives you complete control of the conversion.
In addition to changing formats, the LEADTOOLS PDF Conversion API can convert between PDF and PDF/A, convert between PDF standards versions, linearize PDFs for "Fast Web View", and distill Postscript with optimizations for eBook, screen, and pre-press applications.
PDF Security, Strong Encryption, and Redaction
With standards like HIPPA and GDPR, privacy and the protection of information is a big deal. The LEADTOOLS PDF libraries fully support PDF encryption and PDF Permissions to control editing, printing high and low resolution, and copying content. Additionally, by leveraging PDF image and text redaction and the LEADTOOLS Document Analyzer SDK component, user-defined information such as account numbers and social security numbers can be removed from the PDF automatically.
Document Search and Analysis
The LEADTOOLS PDF libraries provide APIs to find and manipulate PDF content by using string search or RegEx. For even more power, the AI-enhanced LEADTOOLS Document Analyzer component can find fuzzy matches for such things as account numbers, company names, social security numbers, and more.
Compare PDF Files
The LEADTOOLS Document Compare library is an OEM-ready, zero-footprint document-comparison solution for HTML5/JavaScript front ends with a Microsoft .NET (IIS), Java (Linux/Apache), or .NET Core (Kestrel) hosted back end. Developers can add full-featured PDF comparison technology to their application so that end-users can find and see all text insertions, deletions, and edits in two image or text-searchable PDF files.
Secure Digital Signatures
Digital signatures in PDF files are comparable to ink signatures on a paper document, but much more secure. LEADTOOLS PDF SDK libraries can add digital signatures to PDF files, retrieve information from embedded signatures as well as verify signatures ensuring a bad actor has not manipulated the PDF.
Annotate and Mark Up PDF Files
LEADTOOLS supports reading, displaying, editing, and writing PDF annotations and markups that work seamlessly with Adobe Acrobat and other compliant PDF readers. By annotating and marking up PDF files, users can collaborate by writing comments and drawing shapes on top of the document without making permanent changes. Additionally, sensitive information can be permanently or temporarily redacted to help your application comply with standards such as GDPR and HIPPA.
AI-Powered PDF Compression and Optimization
Comprehensive Multipage Processing APIs
Comprehensive multipage features include
- Merge multiple PDF files into a single file
- Split single multipage files into multiple files
- Extract, delete, and insert pages

PDF Parse and Extraction Libraries
With LEADTOOLS, you can parse, update, and extract data such as unicode text and form fields, images, fonts, annotations, shapes, hyperlinks, bookmarks, table of contents, and document metadata. Further, you can update the file settings to set the initial view, create an auto-print PDF, and more.
PDF Portfolio and Attachments APIs
LEADTOOLS SDK libraries can process PDF Portfolio and PDF Attachments, alike. The APIs can extract Portfolio metadata as well as extract all embedded files.
The LEADTOOLS PDF SDK supports:
- Loading PDF Portfolio documents
- Extracting PDF portfolio schema
- Extracting PDF file within PDF Portfolio documents
- Loading PDF documents with embedded attachments
- Extracting PDF attachments embedded within PDF documents
Thorough PDF Bookmark Functionality
The LEADTOOLS PDF SDK libraries provides functions to extract, update, delete and create PDF bookmarks. Bookmarks greatly improve a user's experience as a navigation mechanism to get readers to a specific part of the document quickly.
Proven PDF Forms API
LEADTOOLS PDF APIs provide everything needed to create applications that use existing PDF, FDF, and XFA Forms, such as getting PDF form field information, programatically fill out forms, extract data from forms.
Easy to Integrate

HTML5/JavaScript Document Viewer
The Document Viewer for HTML5 and JavaScript is a zero-footprint component to view raster, text, and document formats. It is ideal for Enterprise Content Management (ECM), document retrieval, and document normalization solutions. The following features are demonstrated:
- Load a document from local disk and url
- Draw annotations on the document
- Use thumbnail viewer for page selection
- View any bookmarks included in the document
- Interactive zooming/panning
- Print documents and annotations
HTML5/JavaScript LEADVIEW
LEAD has packaged the LEADTOOLS Document Viewer web application and service into the LEADVIEW API component. It requires as little as three lines of code to plug the LEADVIEW API into any JavaScript application. The component is highly customizable and supports all the features of the existing low-level Document Viewer, including viewing and converting hundreds of file formats and more than 30 annotation and markup objects. Users can easily create themes for the UI or use the predefined dark or light themes. With a settings dialog or JSON file, the entire ReactJS UI can be customized by each end-user or administratively locked down at a server level.
