Downie is the only video download for OS X you will ever need. It isn't simply another YouTube-downloader: Downie supports at this moment over 700 different sites! The full list may be viewed in Downie's preferences, under the Sites tab.
Supports many sites - currently supports over 750 different sites (including YouTube, Vimeo, etc.) and the number is rapidly growing.
4K video YouTube support - unlike many other YouTube downloaders, Downie supports HD video on YouTube, up to 4K.
Postprocessing - need your video in MP4 for iTunes? Or want just the audio track? No problem, Downie can handle this for you automatically!
Quick support - I respond to emails usually within 24 hours and often add support for requested sites in the next update.
Frequent updates - Don't wait weeks for new sites to be supported, or bugs to be fixed! Downie is updated about once a week with new features, sites supported, etc.
International - not only that Downie supports country-specific sites, it is localized into various languages. If your language is missing, contact us - we can offer you a free license in exchange for a translation.
