Hi Sy,

for something like pdf2txt I would use a viewhelper (which goes in the 
Classes/ViewHelpers folder).

As far as I know it is perfectly fine to use this kind of folder structure:

Classes/ViewHelpers/MyViewHelper.php
Classes/Services/MyService.php
Classes/Helpers/MyHelper.php

Never created a utility before, but I would reckon you check out the 
structure extbase / fluid is using and stick to that.

Good luck!
