Hi. I have a scanned PDF document that alternates paragraphs with white background and greyscale. The white paragraphs are fine and I can edit these ok. However, the paragraphs written on the grey background are being recognised as an image. I tried enhancing but it doesn't work, it is still an image. I have some words I need to delete and replace but I can't do this for any of the grey paragraphs. Any ideas?

You do have a challenge there: The problem is that if you just press the "Scan" button, you will get what you got. What you need to do is to see if your scanner's software can lighten the "whites" so that there is greater contrast between the text and the background.

You can see better what I'm talking about here:

The big problem you have is that if you lighten up the background too much, it will make the "white-boxed" text too light. You will have to make some adjustments to find a happy medium on this.

Any chance you can upload 1 page of the PDF for us to test out?

Hi, Thank you for your reply. I have a page but this is a sensitive document with names of other individuals on it so I do not think I should upload it. I am happy to send it privately if there is a way I can do that?

Acrobat's built-in OCR module isn't the best of breed. Other companies make OCR software that does a better, more accurate interpretation of the text.

Try ABBYY FineReader. https://pdf.abbyy.com/ They have a free trial you can use to test how well it does. Once the PDF file is created, you can then open it in Acrobat and complete the editorial tasts you have. Or FineReader lets you edit PDFs, too. Take your pick!
