PageExpand, developed by hakuhin, is a free Chrome add-on that aims to enhance your browsing experience. With a range of useful features, PageExpand offers users the ability to conveniently access and interact with various online content.

The main function of PageExpand includes a popup image feature, allowing users to easily view images without opening a new tab or window. Additionally, the batch download tool enables users to download multiple files simultaneously, saving time and effort. Another notable feature is the ability to extend anonymous BBS (Bulletin Board Systems) on popular platforms such as 5ch and 2chan, providing users with an enhanced browsing experience.

In addition to the main functions, PageExpand also offers several sub-functions that require user settings. These include expanding thumbnail images, expanding media players, expanding shortened URLs, replacing text with hyperlinks, overriding referer and user agent (abolished in MV3), and customizing the extension through JavaScript (abolished in MV3).
