blog2epub

Convert blog to epub using command line or GUI.

My main goal in creating this app is to preserve the legacy of the blogosphere for future generations.

Supported blogs:

• *.blogspot.com
• *.wordpress.com
• multiple other blogs and even some webpages

Main features

• command line (CLI) and graphic user interface (GUI)
• script downloads all text contents of selected blog to epub file,
• if it's possible, it includes post comments,
• images are downsized (to maximum 800/600px) and converted to grayscale,
• one post = one epub chapter,
• chapters are sorted by date ascending,
• cover is generated automatically from downloaded images.
