This section showcases a cloud platform for PDF storage and electronic signature tasks. Wondershare Document Cloud is a secure storage service dedicated to PDF files, and it comes with several features such as file-sharing, collaborative or personal annotations, file compression, and other useful tools.

Document Cloud is a cloud storage service with a difference - it is exclusively designed to make PDF workloads easier to manage and access from remote locations in a secure manner. Simply upload a file to the cloud using your browser, and you can then share this file with others, combine it with other PDFs, compress the file to reduce the file size, invite others to annotate in a collaborative environment, and so on.
It is also a useful tool when you need to create electronic signatures or send documents for others to sign, either as a group or on individual copies of a PDF file. File-sharing is secure because you can set view or view and comment permissions and even apply a deadline for the share link so you don't have your document floating about in cyberspace after a particular task has been completed.

Step 1 Upload a PDF File to Document Cloud
Save your PDF to the cloud using the Upload Files button on the Home page of Document Cloud.
Step 2 Go to Annotation Mode
Tap the ellipsis (three dots) icon next to the file and select Add Comment. You can now add private notes to the documents.
Step 3 Share a File for collecting feedback from others
To make commenting collaborative, simply click the Share option from the extended menu and share a secure link with another user so they can see and respond to your annotations.
