• Create and edit PDF pages: draw text, vector graphics, images, QR codes, PDF417, DataMatrix, barcodes, annotations, links, outlines, named destinations, metadata, and document properties.
• Page assembly and document repair: split, merge, append, copy, clone, normalize, move, delete, hide, rotate, and rebuild pages from controlled source documents.
• Render and print: switch between GDI+, PDFium, and Cairo rendering engines for screen preview, bitmap export, device-context rendering, and printer workflows.
• Forms and interactive documents: create, fill, edit, flatten, inspect, and manage AcroForm fields, appearances, field flags, JavaScript actions, attachments, and related document data.
• Text, images, and fonts: work with BMP, TIFF, JPEG, JPEG 2000, GIF, PNG, EMF, HTML text boxes, Unicode text, TrueType, OpenType, Type 1, font embedding, font subsetting, and extraction workflows.
• Security and signatures: encrypt and decrypt PDFs with hardware AES-NI acceleration on 32-bit and 64-bit Windows, protect or unprotect multi-gigabyte files through direct file-to-file AES-256 paths that never build the full object graph, set permissions, use public-key recipient encryption, sign with selectable SHA-256/384/512 digests, add PAdES attributes, timestamp signatures, and attach DSS/VRI validation data.
• Huge documents: open PDFs beyond 2 GB with on-demand object loading and 64-bit offsets, merge file lists in a single pass with bookmarks, form fields, and Tagged PDF structure trees preserved, append incremental updates to the source file in place, and copy or rewrite million-object documents in seconds through the Direct Access API.
• Preflight reports and diagnostics: run PDF/A and PDF/UA-1 checks, generate text, JSON, HTML, or CSV reports, compare stable text reports against baselines, batch-process folders with summary CSV output, and audit signature health and document policies at scale with the SigningWorkbench and ComplianceWorkbench demos.
• Low-level PDF control: access object numbers, page dictionaries, catalog entries, output intents, save-version locks, extension-level gates, tiling patterns, optional content, measurement dictionaries, and direct image insertion when your workflow requires precise PDF structure.

• Delphi XE5 through Delphi 13 and C++Builder XE5 through C++Builder 13.
• Native Object Pascal source code for direct Delphi and C++Builder integration, with API reference pages generated for public TPDFlib functions.
• DLL and ActiveX access for C#, VB.NET, VB6, VBA, ASP/ASP.NET, PHP, Visual C++, PowerBuilder, PowerBASIC, RealBasic, and compatible tools.
• 32-bit and 64-bit build options where the target IDE and runtime support them.
• macOS Dylib option for teams that need cross-platform PDF automation around the same library family.
• Standalone demo projects for PDF creation, page operations, image and font handling, forms, encryption, signing, rendering, printing, and preflight report automation.

• Creation and layout: HelloWorld, AddTextImage, CreateTable, DrawWrappedText, TextPaging, AddFormattedTitle, HTML text, barcode, QR code, and image-to-PDF workflows.
• Document operations: CopyPageRanges, PageOperations, ExtractText, ExtractImage, ExtractEmbeddedFonts, ExtractAnnotAttach, DirectAccess, and merge/split style processing.
• Rendering and printing: PdfToImage, MultiFunction renderer selection, PrintPDF, GDI+, PDFium, and Cairo output paths.
• Security and signatures: PdfEncrypt, PdfDecrypt, PdfPermission, PdfSigning, PAdES attribute workflows, DSS/VRI helpers, and timestamp-oriented signing paths.
• Preflight automation: The Delphi PreflightReport demo validates single files or folders, writes text/JSON/HTML/CSV reports, emits preflight-summary.csv, and returns automation-friendly exit codes.

• Choose it when your application must create, modify, sign, validate, and deliver PDFs, not only display them.
• Choose it when your Delphi or C++Builder team needs source-level control, internal diagnostics, and long-term maintainability.
• Choose it when your workflow combines rendering, printing, forms, signatures, encryption, PDF/A, PDF/UA, PAdES, and preflight reports in one toolkit.
• Choose it when CI, archive handoff, accessibility review, or regulated delivery needs stable report files instead of a manual viewer-only check.
• Choose PDFium Component when you only need a focused PDF viewer or renderer, and choose HotPDF when your project needs a lighter PDF creation component.
