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.AddImage().
Optional enhancements like Deskew() improve OCR quality.
Use SaveAsSearchablePdf(...), or output to byte/stream variants for embedding or further processing.
