Make any PDF have Searchable, Copyable Text

IronOCR allows you to embed the recognized text from scanned documents directly into PDFs, making them fully searchable and selectable - perfect for OCR workflows and archival indexing.

Use Configuration.RenderSearchablePdf = true if not using default behavior.
Input is added via input.LoadPdf() or input.LoadImage().
Optional enhancements like Deskew() improve OCR quality.
Use SaveAsSearchablePdf(...), or output to byte/stream variants for embedding or further processing.
