Adobe Bridge works.
In Bridge, create an HTML gallery. In the process, all your JPGS will be created automatically, right from your CR2s.
Essentials/ Output/ HTML Gallery
Choose your JPG file size and quality in Appearance
Preview size (say 800 px)
and quality (say 80 or 100 percent)
Choose your gallery name (say you choose "mygallery")
Choose the directory you want the gallery in. (Say it is called "bigdirectory")
--- BTW, the gallery will be a whole set of files and subdirectories whose root directory is (of course) "mygallery" ---
Select all the CR2s you want converted <--- (important!)
And, voila, all your JPGs will be created, along with the rest of the gallery.
You can find them at
bigdirectory/ mygallery/ content/ bin/ images/ large
This all sounds hard, but it's really very easy.
BTW, the real purpose of this Bridge Output tool is to create a whole gallery, which you can view in a browser by clicking "index.html" in the directory "mygallery".
Of course you can upload to a website the entire "mygallery" directory and its subdirectories and files, in this way creating a web gallery with your images.
Or, as in your case, you can just enjoy the JPGs you got from the CR2 originals.
