The field notes
A little context for your next step.
Use OCR to add a hidden text layer to a scanned PDF so recognized words can be searched and selected. Recognition and text placement can be inaccurate, depending on the scan and language; review the result before relying on it.
Choose a PDF whose pages contain images of text.
OCR recognizes words from page images and adds them as invisible text over the existing pages.
Download the result and check its text, alignment, and page appearance. OCR can miss or misread words.
This tool adds an invisible OCR text layer to the PDF pages. It does not just return a separate text file.
The original page images are kept and the OCR layer is invisible, but OCR text can be misrecognized or misaligned. Review the result.
There is no fixed accuracy guarantee. Results depend on image clarity, language, layout, and other scan conditions. Check important text against the page image.
You can search and select text that OCR recognized. Some words or characters may be missing or incorrect.
The added text layer can increase the file size. The amount depends on the document and the recognized content.
