## Description

Peek is a browser extension that shows interactive previews for links to files and services directly on web pages. Just hover your mouse over a link to open a small popup with a live preview, powered by the browser’s built-in rendering and embedded viewers.

Peek supports a wide range of content—PDFs, Word/Excel/PowerPoint documents, images, videos, and audio—plus popular services like Google Docs Viewer and Microsoft Office Web Viewer. It’s privacy-minded and open-source on GitHub, with previews for many linked formats in lightweight, secure panels.
