Download and Save Videos from Instagram and Vine with Savedeo
Savedeo is an online tool for download videos from a number of popular video sharing sites. Savedeo supports numerous sites including Instagram, Ted, Vimeo, Flickr and Vine. Java is not required on Savedeo - I've yet to find another online tool that reliably works without Java. I would never trust a video download site that uses Java due to a malware risk.
The lack of advertising on Savedeo is very refreshing to see.
