Is there a quick free thing online that lets you open .rar files?

just like no down load or anything

try
http://wobzip.org/ didn’t try nevertheless, but many are stated it works
I like izarc

There is a free system called IZArc which works wonderfully for getting rid of.rar files, but you decide to do have to download in addition to install this.

you must download a program as my partner and i said sooner winrar or maybe 7zip work perfectly.
