Downloadify: Client-Side File Generation

Downloadify is a tiny JavaScript + Flash library that allows you to generate and save files on the fly, in the browser, without server interaction. You can use this solution to reduce the database and server load of your web applications.

Downloadify Uses Flash 10s ability to generate and save files on the user’s computer. Flash 10 requires that a user must click something in the Flash file to trigger the download for security reasons. Downloadify uses JavaScript callbacks to allow your code to respond to the click event and pass in your data at that time.


  • Lightweight
  • Enables the creation and download of any text based file without requiring server interaction
  • Enables faster downloads when repurposing data already contained in a page. (vCard, iCal, etc)
  • Only requires SWFObject
  • No other JavaScript library or framework is required for use
  • jQuery plugin helper included in code
  • Normal, Hover, and Down states on the download image

Developed by Douglas C. Neiner; Downloadify is available for download under MIT License.  You can find further information, demo & download on Downloadify Website.
