PDFMiner is a tool for extracting information from PDF documents.
Unlike other PDF-related tools, it focuses entirely on getting
and analyzing text data. PDFMiner allows one to obtain
the exact location of text in a page, as well as
other information such as fonts or lines.
It includes a PDF converter that can transform PDF files
into other text formats (such as HTML). It has an extensible
PDF parser that can be used for other purposes than text analysis.
pdf2txt.py
pdf2txt.py extracts text contents from a PDF file. It extracts all the text that are to be rendered programmatically, i.e. text represented as ASCII or Unicode strings. It cannot recognize text drawn as images that would require optical character recognition. It also extracts the corresponding locations, font names, font sizes, writing direction (horizontal or vertical) for each text portion. You need to provide a password for protected PDF documents when its access is restricted. You cannot extract any text from a PDF document which does not have extraction permission.
(For details, refer to the html document.)
dumppdf.py
dumppdf.py dumps the internal contents of a PDF file in pseudo-XML format. This program is primarily for debugging purposes, but it's also possible to extract some meaningful contents (e.g. images).

How to Install
- Install Python 2.4 or newer. (Python 3 is not supported.)
- Download the source code.
- Unpack it.
-
Run
setup.py:
$ python setup.py install
-
Do the following test:
$ pdf2txt.py samples/simple1.pdf
For CJK Languages
In order to process CJK languages, do the following before running setup.py install:$ make cmap
python tools/conv_cmap.py pdfminer/cmap Adobe-CNS1 cmaprsrc/cid2code_Adobe_CNS1.txt
reading 'cmaprsrc/cid2code_Adobe_CNS1.txt'...
writing 'CNS1_H.py'...
...
$ python setup.py install
make command,
paste the following commands on a command line prompt:mkdir pdfminer\cmap
python tools\conv_cmap.py -c B5=cp950 -c UniCNS-UTF8=utf-8 pdfminer\cmap Adobe-CNS1 cmaprsrc\cid2code_Adobe_CNS1.txt
python tools\conv_cmap.py -c GBK-EUC=cp936 -c UniGB-UTF8=utf-8 pdfminer\cmap Adobe-GB1 cmaprsrc\cid2code_Adobe_GB1.txt
python tools\conv_cmap.py -c RKSJ=cp932 -c EUC=euc-jp -c UniJIS-UTF8=utf-8 pdfminer\cmap Adobe-Japan1 cmaprsrc\cid2code_Adobe_Japan1.txt
python tools\conv_cmap.py -c KSC-EUC=euc-kr -c KSC-Johab=johab -c KSCms-UHC=cp949 -c UniKS-UTF8=utf-8 pdfminer\cmap Adobe-Korea1 cmaprsrc\cid2code_Adobe_Korea1.txt
python setup.py install
Command Line Tools
PDFMiner comes with two handy tools: pdf2txt.py and dumppdf.py.pdf2txt.py
pdf2txt.py extracts text contents from a PDF file. It extracts all the text that are to be rendered programmatically, i.e. text represented as ASCII or Unicode strings. It cannot recognize text drawn as images that would require optical character recognition. It also extracts the corresponding locations, font names, font sizes, writing direction (horizontal or vertical) for each text portion.
