	Moving from TIFF to JP2 for the storage of digitised masters will not suit every collection or organisation. Benefits can include reduced storage cost (particularly if lossy compression is utilised) and improved user experience (if images are optimised and delivered to browser by an appropriate system). However, these benefits introduce preservation risks (some which are not mitigated by Jpylyzer). Lossy compression lowers the quality of the stored images. The trade off between, cost and risk will be different in different situations. Making an appropriate choice for the collection and organisation in question is essential, and should be guided by [[Understand your collection\|collection needs]], [http://www.scape-project.eu/deliverable/d13-2-catalogue-of-preservation-policy-elements-draft institutional policy], a careful evaluation of the alternatives, practical testing of software with real data, and a clear appreciation of the [[Digital preservation risks\|risks]] involved.
