Isilo conversion

garcianacho · 08-28-2026, 06:08 AM

Hello.

I have developed a converter for the old Isilo format (pdb). It had a proprietary compression and format that made conversion to epub impossible... until now. I have tried it and it works in a high percentage of cases. I think no one had done it until now, and I would be willing to give it up to make a caliber plugin. The bad thing is that no one uses isilo anymore... hahaha. But in case anyone has a relic that they want to keep, I offer it there.
Greetings.

Nacho.

Hello Garcianacho.

Thank you so much for developing this converter and for sharing the news about it. For someone like me who has treasured these old iSilo files for many years, what you have created really means a great deal.

I sincerely hope there might be some way for me to use your converter. I’m not a developer, so I don’t have the ability to turn it into a Calibre plugin myself. If you could possibly help me access or use the converter in whatever form is easiest for you, I would be deeply grateful. It would mean a lot to me to be able to preserve these files and continue reading them on my Android devices.

I would truly appreciate any help you could give me.

I would be very interested in the code you have created to convert isilo files as well. I have several I would like to port and would be happy to use your code and take a crack at creating a Calibre plugin.

Hello, I have quite a few iSilo files i would very much like to convert to epub or something else that preserves its clickableness. I'm not a programmer but I can try my best at adding the plugin to Calibre. My gmail is jocasmalandro@gmail.com
Thank you so much! I've been waiting for this solution for so much time
