Before choosing a method, understand what native OS tools actually do:

• True Dual-Layer OCR (PDF Converter Lab): Embeds an invisible text layer directly inside the

  text

  Ctrl + F

Does Windows 11 have built-in PDF OCR?

Windows 11 includes Snipping Tool text actions and PowerToys, but neither can embed an invisible searchable text layer inside a multi-page PDF file. You need a dedicated tool like PDF Converter Lab.

No. Preview can display and let you copy text via Live Text, but it cannot inject a persistent text stream into the underlying PDF file.
