I had evaluated several Third Party OCR SDK''s in one of my assignment. In case if you are open for Third Party OCR SDK then search below SDK''s on Google.

1) Nuance OmniPage OCR
2) Accusoft SmartZone OCR

我同意Simon的观点:如果PDF是扫描图像，则需要OCR，这并不容易.

请在过去的解决方案中查看我对OCR的建议 OCR软件 [

I agree with Simon: if the PDF is a scanned image, you will need OCR, which is not easy.

Please see my advice on OCR in my past solution OCR Software[^].
