In macOS 12 (Monterey), there is a new feature called Live Text. It can recognize text in the images by OCR.
MacOS's Preview app lets you select text in an image file, and also lets you convert the image to a PDF file. Meanwhile, I did not find a way to export the image into a searchable PDF which can let you search and select text in that exported PDF file.
Is there any way to convert images into a search PDF file in macOS Monterey with Live Text (OCR)?
