Hover Zoom+ is a Chrome-only extension that enlarges any image or video you hover over on a live webpage, without opening it in a new tab or downloading it first.
It pulls the full-resolution source straight off the page's underlying markup, so you can see a thumbnail, product photo, or video preview at real size on sites like Amazon or Pinterest: something plain browser zoom or a quick devtools poke won't give you as cleanly.
Reach for it when you're scanning a competitor's product gallery or a stock-photo grid and want to check an image's quality or composition at full size before you screenshot or reference it.
This is a from-scratch open-source rebuild of the original Hover Zoom, which Google pulled from the Chrome Web Store in 2019 after it was caught secretly harvesting users' full browsing history (the "DataSpii" scandal); this fork claims to collect nothing, but it still needs "read and change all your data on all websites" permission, so weigh that against the convenience.
Zoom images and videos on all your favorite websites by hovering your mouse.
