Create, edit, and automate PDF documents directly within your applications.
PDF SDK is a software development library for integrating Portable Document Format (PDF) creation, editing, and processing into applications. Developers can generate documents, modify existing content, manage interactive forms, and automate document workflows. It also supports electronic invoicing, archival compliance, and direct access to PDF objects for detailed document manipulation.

PDF Document Generation

Create single-page and multi-page PDF documents programmatically, including invoices, reports, letters, contracts, and other business documents. Define page layouts, position content, and control formatting through application code to generate documents that meet specific presentation and workflow requirements.

Advanced Text Formatting and Layout

Customize PDF content with precise text positioning, formatting options, lists, and tables. Control how information appears on each page, allowing applications to produce structured documents with consistent layouts, readable content, and presentation styles suited to different document types.

Image and Vector Drawing Support

Insert images and create vector drawings directly within PDF documents. Position graphical elements alongside text and other content to produce customized document layouts. Add partially transparent watermarks to incorporate visual identifiers or background information without obscuring the main document content.

Existing PDF Content Editing

Modify existing PDF documents without converting them into intermediate file formats. Edit text, images, and visual elements directly within the document structure. This enables applications to update document content while avoiding the formatting changes that can occur during file conversion.

Interactive PDF Form Management

Create, modify, and populate fillable PDF forms through application code. Add and update form fields to support interactive document workflows, automate data entry, and process information within existing forms. Integrate form management capabilities into applications that handle structured document submissions.

PDF Merging and Splitting

Combine multiple PDF files into a single document or split existing documents into separate files. Manage document pages programmatically to organize related content, extract sections, and prepare files for distribution, storage, or further processing within automated document workflows.

Electronic Invoice Generation and Processing

Create and process electronic invoices using the ZUGFeRD/Factur-X standard. Embed structured Extensible Markup Language (XML) data within PDF documents to combine readable invoice content with machine-readable information. Support automated invoice processing and electronic invoicing workflows that require standardized document formats.

PDF/A Archival Compliance

Generate and process documents that meet PDF/A archival requirements, with support for PDF/A conformance levels. Applicable components preserve PDF/A compliance during document operations, allowing applications to maintain archival requirements when creating or modifying documents intended for long-term storage.

Low-Level PDF Object Access

Inspect and modify individual PDF objects to access the underlying document structure. Examine internal elements, investigate document issues, and perform detailed modifications beyond standard editing operations. This provides developers with additional control when implementing advanced PDF processing and debugging functionality.

Application Integration and Document Automation

Integrate PDF processing capabilities into software applications using development components and a unified object model. Automate document generation, content updates, form handling, and file manipulation through programming interfaces, supporting workflows that require PDF processing without manual document editing.
