    Hey all!

    Could anybody help me? I'm seeking for free .NET component which can get text from PDF and push it into text file. Do you know any?

    My purpose is creation of small console utility which can perform convertion from command line for many PDF files.

    Text Mining Tool can help you. I have been using it for last two weeks - free, stable, good software.

    I have to admit to being a tiny bit unsure about this, but as far as I remember text extraction from PDFs isn't foolproof; this is because text can be formed in a PDF in one of three ways:
    1. As a proper marked-up text block
    2. As a series of vector shapes without any indication that what's being drawn are actually letters
    3. As a bitmap (for example, a scanned document)
    Getting text from (1) is relatively simple (though there's often work involved in figuring out how all of the text blocks are positioned relative to each other, but I'm sure that text mining tool thingy does that fine). Getting text from (2) or (3) though essentially requires an OCR engine.

    Basically, you should check the type of documents you've got in Acrobat or similar; if the text can be selected within Acrobat, you're laughing, if not, you may have more work ahead of you.
