PyPDFOCR - Tesseract-OCR based PDF filing

|image0| |image1| |Coverage Status|

This program will help manage your scanned PDFs by doing the following:

Single conversion:


    pypdfocr filename.pdf

    --> filename_ocr.pdf will be generated

If you have a language pack installed, then you can specify it with the
``-l`` option:


    pypdfocr -l spa filename.pdf

Folder monitoring:


pypdfocr -w watch_directory

--> Every time a pdf file is added to `watch_directory` it will be OCR'ed

Automatic filing:

To automatically move the OCR'ed pdf to a directory based on a keyword,
use the -f option and specify a configuration file (described below):


    pypdfocr filename.pdf -f -c config.yaml

You can also do this in folder monitoring mode:


    pypdfocr -w watch_directory -f -c config.yaml

Filing based on filename match:

If no keywords match the contents of the filename, you can optionally allow it to fallback to trying to find keyword matches with the PDF filename using the -n option. For example, you may have receipts always named as receipt_2013_12_2.pdf by your scanner, and you want to move this to a folder called 'receipts'. Assuming you have a keyword receipt matching to folder receipts in your configuration file as described below, you can run the following and have this filed even if the content of the pdf does not contain the text 'receipt':


pypdfocr filename.pdf -f -c config.yaml -n

Configuration file for automatic PDF filing ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

The config.yaml file above is a simple folder to keyword matching text file. It determines where your OCR'ed PDFs (and optionally, the original scanned PDF) are placed after processing. An example is given below:


target_folder: "docs/filed"
default_folder: "docs/filed/manual_sort"
original_move_folder: "docs/originals"

        - american express
        - chase card
        - internal revenue service
        - boarding pass
        - airlines
        - expedia
        - orbitz
        - receipt

The target_folder is the root of your filing cabinet. Any PDF moving will happen in sub-directories under this directory.

The folders section defines your filing directories and the keywords associated with them. In this example, we have three filing directories (finances, travl, receipts), and some associated keywords for each filing directory. For example, if your OCR'ed PDF contains the phrase "american express" (in any upper/lower case), it will be filed into docs/filed/finances

The default_folder is where the OCR'ed PDF is moved to if there is no keyword match.

The original_move_folder is optional (you can comment it out with # in front of that line), but if specified, the original scanned PDF is moved into this directory after OCR is done. Otherwise, if this field is not present or commented out, your original PDF will stay where it was found.

If there is any naming conflict during filing, the program will add an underscore followed by a number to each filename, in order to avoid overwriting files that may already be present.

Evernote upload:

Evernote authentication token

To enable Evernote support, you will need to `get a developer token for
your Evernote
account. <>`__. You
should note that this script will never delete or modify existing notes
in your account, and limits itself to creating new Notebooks and Notes.
Once you get that token, you copy and paste it into your configuration
file as shown below

Evernote filing usage

To automatically upload the OCR'ed pdf to a folder based on a keyword,
use the ``-e`` option instead of the ``-f`` auto filing option.


    pypdfocr filename.pdf -e -c config.yaml

Similarly, you can also do this in folder monitoring mode:


    pypdfocr -w watch_directory -e -c config.yaml

Evernote filing configuration file

The config file shown above only needs to change slightly. The folders
section is completely unchanged, but note that ``target_folder`` is the
name of your "Notebook stack" in Evernote, and the ``default_folder``
should just be the default Evernote upload notebook name.


    target_folder: "evernote_stack"
    default_folder: "default"
    original_move_folder: "docs/originals"
    evernote_developer_token: "YOUR_TOKEN"

            - american express
            - chase card
            - internal revenue service
            - boarding pass
            - airlines
            - expedia
            - orbitz
            - receipt

Auto email

You can have PyPDFOCR email you everytime it converts a file and files
it. You need to first specify the following lines in the configuration
file and then use the ``-m`` option when invoking ``pypdfocr``:


    mail_smtp_server: ""
    mail_smtp_login: ""
    mail_smtp_password: "PASSWORD"
    mail_from_addr: ""
        - ""
        - ""

Fine-tuning Tesseract/Ghostscript

At the moment, the only options allowed for Tesseract and Ghostscript are specifying their executable locations manually. Use the following in your configuration file:


    binary: "/usr/bin/tesseract"

    binary: "/usr/local/bin/gs"


Using pip

PyPDFOCR is available in PyPI, so you can just run:


    pip install pypdfocr

For those on **Windows**, because it's such a pain to get all the PIL
and PDF dependencies installed, I've gone ahead and made an executable
`pypdfocr.exe <>`__

You still need to install Tesseract and GhostScript as detailed below in
the external dependencies list.

Manual install

Clone the source directly from github (you need to have git installed):


git clone

Then, install the following third-party python libraries:

These can all be installed via pip:


pip install pil
pip install reportlab
pip install watchdog
pip install pypdf2

You will also need to install the external dependencies listed below.

External Dependencies

PyPDFOCR relies on the following (free) programs being installed and in the path:

In addition, if you want it to figure out the original PDF resolution automatically, you need to have pdfimages in your path, which is part of the xpdf <>__ or poppler packages.

On Mac OS X, you can install these using homebrew:


brew install tesseract
brew install ghostscript
brew install poppler
brew install imagemagick

On Windows, please use the installers provided on their download pages.

** Important ** Tesseract version 3.02.02 or newer required (apparently 3.02.01-6 and possibly others do not work due to a hocr output format change that I'm not planning to address). On Ubuntu, you may need to compile and install it manually by following these instructions <>__

Also note that if you want Tesseract to recognize rotated documents (upside down, or rotated 90 degrees) then you need to find your tessdata directory and do the following:


cd /usr/local/share/tessdata 
cp eng.traineddata osd.traineddata 

osd stands for Orientation and Script Detection, so you need to copy the .traineddata for whatever language you want to scan in as osd.traineddata. If you don't do this step, then any landscape document will produce garbage
