MPC Deck Previewer is a Chrome extension designed to enhance the user experience for those creating custom playing cards on MakePlayingCards.com. This free add-on integrates seamlessly by adding 'Preview' links to saved projects, allowing users to easily access their card designs. Upon clicking the preview link, a new tab opens, displaying all selected card images, enabling users to flip each card individually or all at once using simple controls.

In addition to its primary functionality, the extension offers the option to revert to the original previewer from MakePlayingCards.com, which presents images side by side. However, this original format may be less visually accommodating due to the smaller image sizes. Overall, MPC Deck Previewer serves as a practical tool for card designers seeking a more efficient way to review their projects.
