Compressing Files for Sharing

Bundle it up and make sure it's actually small enough to send.

Bundling multiple files into one archive comes first since it's usually the actual goal -- sending several files as one attachment instead of many separate ones. Checking the final size against an actual limit is a genuinely separate, worthwhile second step, since a zipped bundle can still end up too large for a given email provider or upload form, and it's better to catch that before attempting to send it than after it bounces.

Each step opens as its own tool -- download from one, upload into the next, same as any free tool on the site.
