just downloaded a PDF document and it came up saying I couldn't make any changes because the text was renderable. I did try to say each page as a TIFF and used the Recognize Text Using OCR but I cannot delete the text in my document.
If downloaded PDF's content is a scanned image then there is not text per se; just the image of text.
OCR can provide a hidden layer of recognzed text.
A PDF with such a hidden layer can have this OCR output delected.
Use "Examine Document" then use the button at the bottom of the dialog to remove those items ticked in the dialog.
To delete scanned images of characters you'd have to use a photo editor or use the redact tool.
If the downloaded PDF's content is from an authoring application (such as MS Word) the PDF's there is renderable text.
A PDF page with any renderable text cannot undergo Acrobat's OCR.
A PDF like this cannot be treated as something else such as a TIFF.
Document security may have been applied to the PDF such that changing (edit/delete) is precluded.
Not sure which applies.
When you begin the OCR process, you have the option to set the PDF Output Style. If you need to edit the text, I would recommend selecting CleanScan. The ClearScan process converts the words on the page to actual text that can be edited. The other options, Searchable Image and Searchable Image (Exact) will produce an image of the scan and then place an invisible layer of text underneath so that you can still search for words within the file. The last option - Searchable Image (Exact) is used a lot for legal documents where it's a necessity to maintain an exact representation of the original page.
Here is a quick tutorial that explains the process of using ClearScan to facilitate editing text from a scanned image.
