Peek: Browser Extension for Previewing Documents, Videos, and More
Peek is a free browser extension developed by Corbin Davenport that allows users to preview various types of files and supported services with a simple mouse hover. This handy tool eliminates the need to open multiple tabs or download files to view their content.
By hovering your mouse over a link, Peek displays a small popup with an interactive preview of the link's content. It supports a wide range of file types including PDF, TXT, RTF documents, WebM, MP4, M4V, OGG, OGV, and Imgur GIFV videos, MP3, M4A, OGA, OGG, WAV audio, Word, Excel, PowerPoint, and OpenDocument files, as well as various image formats like JPG, PNG, APNG, SVG, GIF, ICO, and BMP.
Peek goes beyond just file previews, as it also supports previewing Google Docs links, iCloud Keynote links, YouTube videos and YouTube Shorts, Reddit links, Imgur links, and TikTok videos. This makes it incredibly versatile for users who frequently encounter these types of content.
The extension leverages the browser's built-in rendering features along with the Google Docs Viewer, Microsoft Office Web Viewer, and other third-party embedded viewers to provide rich and interactive previews. With Peek, users can quickly assess the content of a file or link without the need for additional clicks or downloads.
Peek is an open-source project released under the GPL license, which means the code is freely available on GitHub for those interested in exploring or contributing to its development.
