photoshop - How do I constrain filesize of a bunch of photos?

I have a bunch of photos of jewelry that I need to upload to a website. Unfortunately there is a 2MB file size limit. Most of the photos are JPEGs over 3MB.

I want to keep the aspect ratio, meta data, and highest quality possible at under 2MB. Adobe Bridge will allow me to set an image size limit when I export, but not the file size.

Does anyone know of a way to render the images with a max filesize limit?

Answer

I don't believe Bridge has this functionality.

Photoshop and Lightroom (with a mogrify plugin) have this ability to set a file size based export.
