About Peek

Peek is a browser extension that shows previews for links to files and supported services in web pages. Hovering the mouse over a link opens a small popup with an interactive preview of that link's content, covering PDFs, Microsoft Office documents, images, video and audio files, and links to services such as YouTube, Google Docs, Spotify, iCloud Keynote, Reddit, Imgur, TikTok, Mastodon, Facebook, Instagram and Threads. Rich previews are displayed using the browser's built-in rendering features together with third-party embedded viewers, including Google Docs Viewer and Microsoft Office Web Viewer. The extension is available for Google Chrome, Firefox (version 106 or later) and Microsoft Edge, and the source is published on GitHub under the GPL-3.0 license.
