Send files directly from Microsoft Office
Zip and email documents, spreadsheets and presentations directly from Microsoft Office 2010, 2013 and 2016. Whether you're working in Word, Excel, PowerPoint or Outlook, you can zip, convert, encrypt and email without skipping a beat.
Tap into the power of WinZip
Automatically zip outgoing email attachments using WinZip's world-leading file compression technology to reduce file sizes and protect your files.
Works with free ZipShare
Courier 7 connects directly to ZipShare, the WinZip file sharing service, automatically uploading your zipped file and adding a link to your outgoing email message. ZipShare is a web app, so you can also use it from almost any device or computer to zip and send files, or access your connected cloud services.
Take advantage of your clouds
Are your files still too big to email? Courier will automatically upload them to one of your connected cloud services and place a download link in your email message. Courier works with ZipShare, WinZip's file sharing service, and Box, OneDrive, Dropbox, Google Drive, CloudMe, SugarSync and MediaFire.
Safeguard private information
Now administrators can enable FIPS 140 handling in Courier when it is used with WinZip Enterprise. Courier also offers built-in 128- or 256-bit AES encryption and password protection makes it easy for you to secure your files. Use Courier's manual or automatic options to control the encryption process. Courier also wipes/shreds temporary files to ensure the security of attachments shared over email.
Easily convert files for better sharing
Convert files to PDF directly from your Microsoft Office 2010, 2013 and 2016 apps, including Word, Excel and PowerPoint. For extra protection, you can create a read-only PDF to deter copying. Courier also lets you add watermarks to your images to protect your work. For photos, resize high-resolution images to more convenient sharing sizes. Apply conversions as your attachments are zipped, or apply to a single unzipped attachment for instant sharing.
Browse attachments
Get a look at the contents of incoming zipped attachments without having to extract files. In the Microsoft Outlook preview pane, simply click on the Zip file's icon to expand a list of its contents. You can also open/edit individual files directly from this list.
Apply conversions without zipping
Apply watermarks, resize images and convert to PDF even if you choose not to zip your attachment. For example, you could add a watermark and resize an image to keep it within maximum message size restrictions without zipping, allowing your recipient to view the image immediately.
Easily add shared links
Insert shared links in Microsoft Outlook plain text messages and in the (Hotmail) "Edit in HTML" feature.
