QuickLook Video for MAC

Free, open-source Mac app that adds Finder thumbnails, Quick Look previews and Get Info details for MKV, AVI, WebM and more.

QuickLook Video Overview

QuickLook Video, also known as QLVideo, teaches your Mac to understand many more audio and video files. Out of the box, Finder, Quick Look and Spotlight only handle a limited set of formats. With QuickLook Video installed you get Finder thumbnails, Quick Look previews and details in the Get Info window for files such as Matroska (MKV), WebM, AVI, Windows Media, Ogg, Flash Video and Real Media, with codecs including VP8, VP9, AV1, HEVC, Theora, DivX and many more.

Version 3 works with Media Extensions that add these formats and codecs to macOS's own media system, much as Perian did for older versions of QuickTime. A View Contact Sheet entry in Finder's Services menu shows a grid of frames from a video. QuickLook Video is made by Jonathan Harris and is free and open source under the GPL-2.0 license; the developer also sells it on the Mac App Store. Version 3.12 needs macOS 26 Tahoe or later.
