Batch convert WebP files back to PNG

[tuqueque tuquequin]

Hi, maybe is a stupid question that has been answered before, but...

I use WebP (through a nifty little script "MultiWebP" from: http://metal03326.blogspot.com/2012/05/converting-multiple-files-into-webp.html) to archive my PNG sequences after I finish a project to save space (TV commercials and stuff like that). But my client asked for a couple of corrections after I did the WebP conversion and the software I use (Blender) doesn't support (yet) WebP format... So, how can I batch convert those WebP sequences back to PNG?

Thanks in advance.

The opposite has come up, but the solution still applies [1]. Change cwebp to dwebp and the extension to .webp. dwebp's default output is png. 

Thanks in advance.

Thank you very much, James. I didn't know dwebp was for that... So easy!

I modified the "MultyWebP" from my last post to use dwebp instead of cwebp (and a couple more changes) and it worked like a charm!

Thanks again.
