Zamzar, the home of the popular online file conversion service, also offers a browser plugin that’s a must-have for any Internet Explorer user. The Zamzar web browser button is a bookmarklet you can add to your bookmarks toolbar folder in your web browser. With the bookmarklet installed, you’re then able to convert any files you find on the web and download them to your computer. To use the web browser button, just click on it when you’re on any website that contains files. Zamzar will auto-detect all the files on the page that can be converted and will highlight them for you. You can then choose which ones you want to convert and what format you want them converted to. You can even use the button to convert online videos from sites like YouTube. (A full list of supported video sites is here). I love this plugin, but I’m not a fan of all the pop-up ads on Zamzar’s website – so be warned. However, I don’t get pop-ups when using the plugin – only when visiting the Zamzar homepage. Still, the plugin is worth the annoyance, I suppose, at least until something better comes along.
