I present the OSIRIS Data Reduction System. This consists of an offline system (OOPS -- OSIRIS Offline Pipeline Software) and an online system (OQuLTo -- OSIRIS Quick Look Tool). Both programs are written in Python/PyRAF and offer a user-friendly, quick and intuitive way to reduce OSIRIS data in any observing mode. The graphic user interface of OOPS makes it a unique (so far) tool both for its flexibility and power. The whole software is based on freely available modules, hence making it accessible to everybody.
