Now and then I come across a PDF which looks fine in first place but the underlying text is garbled. Currently I have a PDF where only the headings are garbled and I would like to know if it's possible to somehow replace the garbled text with the correct one.

I thought about OCRing the specific pages but this only works if I convert the page to an image.

How can I manually correct the underlying text or the re-OCR only specific parts?

In Acrobat Pro: Veiw --> Tools --> Recognize Text

will bring up the OCR tool bar. From there, use the "OCR Suspects" tools to correct the errors in the PDF.

Thanks! But this doesn't work since this document hasn't been OCRed. There are no "OCR Suspects". It's an "Vector-PDF" with copyable text. But the copied text of the headers is garbled. – TheLostOne Feb 15 '12 at 18:25
