Compress That Large Annoying PDF
Upload a PDF, and we'll compress it!
Est run time: 10-15s.
Usefulness: We've all had that experience where we needed to send a PDF last minute only to get a warning from Google that the file is too big, and by the time we finish reading the error message, the deadline has passed, and now it's yet another season I won't be on American Idol.
Caveats: If your file is already compressed, the tool will not make a difference - and may even increase it by a few KB.
