Comparison
Choose the right PDF library
All three read, render, sign, and validate PDFs, and all three ship complete Object Pascal source with royalty-free deployment. They differ in what they can do that the others cannot, and in what you have to ship alongside your application.
| Library | Best fit | What only this one does | Deployment |
|---|---|---|---|
| HotPDF Component | Creating and editing PDFs with nothing to ship alongside | Its own rendering engine and image codecs (JBIG2, JPEG 2000, CCITT, TIFF), a complete Type1 / OpenType font engine, barcode generation (QR, Data Matrix, PDF417), XFA layout, Factur-X e-invoice validation, HTML import, SVG export, document comparison, and an embedded JavaScript engine | Compiles into your executable. No PDF runtime to redistribute, version-match, or clear through a deployment audit |
| PDF Library for Delphi | One toolkit for the whole document lifecycle | Native OCR, barcode reading as well as writing, PKCS#11 hardware-token signing, EU trust-list validation, Arlington PDF Model checking, DOCX / HTML / Markdown export, hyphenated text flow, and parallel rendering | Object Pascal source, plus DLL, ActiveX and Dylib entry points when non-Delphi code has to call in |
| PDFium Delphi Component | Reading, reviewing, and compliance work | An accessible read-aloud architecture, table extraction to CSV / JSON, semantic reflow into HTML, progressive loading of remote documents, and PAdES B-B through B-LTA signing including remote and HSM workflows | Ships pdfium.dll next to your application; optional V8 / XFA runtime for those features |
Choose HotPDF when the application generates documents and you cannot or would rather not redistribute a rendering engine. Choose PDF Library for Delphi when one toolkit has to cover the full lifecycle, or when OCR, hardware-token signing, or non-Delphi callers are in scope. Choose PDFium Delphi Component when the work is reading, reviewing, and proving compliance rather than authoring.
