pdf-compressor

Compress PDF file's pages and size.

Introduction

A light-weight tool to compress PDF file's pages and size. The compressing loses origin file's format, only the text information is saved in the compressed result.

With default font size 10, the compressing effect looks like:

$ python main.py -i input.pdf
File size (KB):         15114.015----> 45.828
Page count:             23 --------> 15

By setting the font size smaller to 5:

$ python main.py -i input.pdf -f 5
File size (KB):         15114.015----> 31.638
Page count:             23 --------> 4

Below is a glance of the process, from left to right: origin file -> compressed file -> compressed file with font size 5.
