Why compress PDF before emailing?
Email servers have strict attachment limits. Gmail caps attachments at 25MB, Outlook at 20MB, and many corporate email systems at 10MB or less. A compressed PDF loads faster for the recipient, uses less storage, and never gets rejected by the mail server.

You can upload PDFs up to 50MB for compression.
How much smaller will my PDF get?
