## What it is
iText is a high-performance PDF library/SDK for Java and .NET that lets developers create, manipulate, inspect, sign, and secure PDF documents. It supports PDF/A and PDF/UA standards, digital signatures (PAdES), forms, encryption, barcodes, and SVG, with add-ons for HTML-to-PDF conversion, OCR, redaction, and international scripts.

## Use cases
- generate pdf invoices from java application
- merge multiple pdf files into one
- digitally sign pdf documents with pades
- fill and flatten pdf forms programmatically
- convert html to pdf
- create accessible pdf/ua documents
- extract text and images from pdfs
- add watermarks and barcodes to pdfs

## When to choose
- you need comprehensive, standards-compliant PDF creation and manipulation in Java or .NET
- you need PDF/A archiving, PDF/UA accessibility, or PAdES digital signatures
- you need to handle large multi-gigabyte PDFs and thousands of pages
- you can comply with AGPL or purchase a commercial license
- you need advanced features like FIPS-compliant cryptography or international script support

## When to avoid
- you need a permissively licensed library and cannot open-source your application under AGPL
- you only need simple PDF viewing or rendering rather than generation/manipulation
- you want a free closed-source solution without commercial licensing costs
- you need a lightweight dependency for basic PDF tasks that simpler libraries can handle

## Facets
- artifact type: library
- maturity: stable
- function: pdf, security, cryptography, ocr, image-processing, parser, internationalization
- domain: pdf, files, developer-tools, security
- platform: jvm, dotnet, cross-platform
- tags: pdf-generation, pdf-manipulation, digital-signatures, pdfa, pdfua, acroforms, dual-license, agpl, barcode, svg, html-to-pdf, localization
