Is there any (free?) software that will help me to convert existing JPG files into a specific file size on disk?
(I assume that the software will estimate accurately compressed file size during the save.)

Irfanview is pretty good and does it for jpeg- just install it WITH the plugins and setting file size should be a save option. I quite like Irfanview in fact, it's light, easy, quick and does batch operations nicely :)
The command line ImageMagick supports a maximum file size:
-define jpeg:extent=400kb
Paint.NET gives the file size when saving:
Simply change the quality setting to get the size you want.
For quick and easy image resize I always use and recommend Picture-Resize. It's very easy to use and blazing fast.

It does not have a GUI, you just change the filename in order to change the parameters of the image resize operation. A very unusual but cool way to operate.
Irfanview with the Save-for-Web plugin does this.
In irfanView, the plugin is accessible via "File", "Save for web (plugin)". There's a "Compress for size" option that lets you enter a desired file size and then makes an approximation of what you entered.
