title: How to convert PNG to GIF using javascript or other client-side tech?
body: <p>I have a combination of client-side technologies creating PNG data in the browser. Is there a way to convert the PNG data to GIF for display in IE without sending the data to the server? Wondering if there is an existing JavaScript library that will parse the PNG data and output GIF, or even JPEG. I know that I can send the PNG data to a server and have PHP / Python / or whatever generate a file for display in IE, but I'm aiming to keep this all on the client side even if the processing of the image is somewhat slow.</p>
  
  <p>UPDATE:
  No obvious existing JavaScript libraries to do this, so I'll use Flash to convert image data to GIF output for IE and continue to use PNG for all other browsers.</p>
