Wanted to convert pdf to text on linux mint and looked around. The option under the software manager in linux mint shows Tesseract .You have to install a 3rd party GUI also to use it . I used YAGF.
Note this program is a memory hog and can freeze your comp if you are doing multiple things

Version: 3.02.02-1
Size: 29MB to download, 78MB of disk space required
Impact on packages: liblept3 (installed), tesseract-ocr-eng (installed), tesseract-ocr-equ (installed), tesseract-ocr-osd (installed), tesseract-ocr (installed), libtesseract3 (installed)
The Tesseract OCR engine was one of the top 3 engines in the 1995 UNLV Accuracy test. Between 1995 and 2006 it had little work done on it, but since then it has been improved extensively by Google and is probably one of the most accurate open source OCR engines available. It can read a wide variety of image formats and convert them to text in over 40 languages.

Tesseract doesn't have a built-in GUI, but there are several available from the 3rdParty page.

YAGF is a graphical interface for cuneiform and tesseract text recognition tools on the Linux platform. With YAGF you can scan images via XSane, import pages from PDF documents, perform images preprocessing and recognize texts using cuneiform from a single command centre. YAGF also makes it easy to scan and recognize several images sequentially.
