then click Enhanced scans in the toolbar to the right of the document. Whereas it might take that long to find your way through Acrobat's menus to do the same thing. We've had mixed results over the years, but usually the only problem is that it can take a few minutes. When you open an image document that has text in it, PDFpen recognizes it and offers to scan it for you. PDFpen is by far the easiest to use for this. If instead the PDF was created by scanning a paper document, it won't have that copyable text, it will just be an image of text. This is because the application in which the PDF document was first created has saved a text layer, it has made this copy and paste easy. If you open a regular PDF in Preview, you can usually select the text and copy it. There is one last feature that makes third-party PDF apps useful and that is their ability to use OCR.

PDF Studio Pro gives you the ability to display two PDF files side by side or overlay them with the differences highlighted in colors. If you must get those two backwards, Acrobat's annotations will tell you the differences, but it will get you wrong about which came first. It requires you to call one copy of the PDF 'new' and a second 'old'. You need to be able to compare versions of PDF files and that's something else preview can't do.Īdobe Acrobat has a Compare files feature that is exhaustive but should be used with care. There are times when a contract has been negotiated and one party has made a substantial change to the PDF without informing the other party. And unfortunately, there are also some people who rely on that fact to get away with changes. There are a lot of people out there who don't realize that you can edit PDF files like this. However, each of these apps allows you to replace an image, so if your company newsletter is about to go out when the CEO is unexpectedly replaced, you can change your image to the new person.
However, for extracting images to work on other documents it's particularly good, although PDF Studio Pro allows you to export some or all of the graphics directly. However, it's not a round trip, or at least we could never find a way to automatically retrieve the edited image in the PDF. Only Acrobat allows you to send an image from within a PDF to a graphics editor of your choice. PDF Studio Pro allows you to change the DPI of an image, which could be useful for reducing the size of your entire PDF. It's the same with all of these top apps, though each one tends to get the job done in different ways. So it's useful for making small changes to improve the look of a document, but it can't make the text flow around the new image size.
Adobe Acrobat allows you to crop or resize an image, but if you do, the rest of the PDF page remains as it was.
