Converting non-animated .gifs

I am trying to make myself a small application, but I have to import an image to a sprite. The problem is that it's a gif. I do not know if there would be a way to convert gifs to pngs, but if not I can always make different animations for the sprite and set the sprite to animation <font face="Courier New, Courier, mono">global('weather')</font> instead of downloading <font face="Courier New, Courier, mono">"http://icons.wxug.com/i/c/a/" & global('weather') & ".gif"</font> as <font face="Courier New, Courier, mono">AppPath & "icon.gif"</font> and setting the sprite to it. The images I am trying to set are the ones in the Icon Pack 1 on Weather Underground.

The images are being downloaded from an online location, and they are not animated. Should I download them manually and save as animations for the sprite? I would have the ability to even create custom images, then!

Examples (images link to source):

You'll need to break the gif animation into separate sprite/frames, and then import them as "frames" into the animations of the object. This is due to Construct Classic using its own method of animating.
