Download WinZip Courier
Free yourself from email size limits and deliver large files safely! Courier integrates seamlessly with your email system to automatically zip and encrypt outgoing attachments as you work. Simply write an email, attach as many files as you need, and click Send—Courier will take care of the rest! Files still too big? Courier will automatically send them via the ZipShare web service (up to 2GB per message).
WinZip Courier requires Windows Vista, Windows 7, Windows 8.x, or Windows 10.
Courier integrates seamlessly with any of the following email and web mail applications:
- Microsoft Outlook 2007, 2010 (32-bit or 64-bit version), 2013 (32-bit or 64-bit version)
- Yahoo! Mail
Courier works with the webmail listed above when used with the following browsers:
- Microsoft Internet Explorer 8-11
- Google Chrome 6-44
- Mozilla Firefox 3.5-39
NOTE: Due to its lack of browser add-in support, Windows Edge is not supported at this time.

These requirements only apply to the computer system where WinZip Courier is installed. Recipients of your email attachments can use any email program to read your email; however, to open and extract the attached Zip files, your recipients may need file compression software such as WinZip Standard or WinZip Pro.
