Email attachments are usually rather small, since they mostly contain images, documents or presentations that do not require too much disk space. However, some email clients and services might pose some size limits, which can cause you trouble if you intend on sending larger documents using the attachment function.

Safeguard private information
Courier offers built-in 128- or 256-bit AES encryption and password protection to make 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 Microsoft Office, 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, enabling your recipient to view the image immediately.

Easily add shared links
Insert shared links in Microsoft Outlook plain text messages and in the Outlook.com (Hotmail) "Edit in HTML" feature.
