Understand how Acrobat protects your files during the sending process through encryption and strict access controls.

Adobe Acrobat online services, including the Send feature, employ industry-standard security practices to protect your data. When you share files via Acrobat.com, the data is protected both in transit and at rest.

By utilizing secure cloud infrastructure, your documents are shielded from unauthorized access. The connections are encrypted using TLS (Transport Layer Security), and stored files are encrypted using AES (Advanced Encryption Standard). Users can also add additional layers of security, such as password protection, to specific PDFs before sending them.

Prepare your document

Open Adobe Acrobat and load the PDF file you wish to share.

Apply local encryption (Optional)

For highly sensitive information, go to 'Protect' > 'Protect Using Password' to set a viewing password before initiating the share process.

Initiate the secure send feature

Click on the 'Share' or 'Send for Review' button located in the top right corner of the application interface.

Send to recipients

Enter the recipient's email address and send the file. The transfer will automatically route through Adobe's secure HTTPS/TLS encrypted connection.

Frequently Asked Questions

Can I password protect a PDF before sending it online?

Yes. In most professional PDF editors like Adobe Acrobat and WPS Office, you can encrypt your document with a password before uploading or sharing. Navigate to the 'Protect' tab and select 'Encrypt with Password' to ensure only authorized recipients can open the file.

What encryption standard is used for online file sharing?

Most professional document services, including Acrobat.com and WPS Cloud, use TLS (Transport Layer Security) to protect data in transit and AES (Advanced Encryption Standard) for data at rest. This combination ensures maximum security against interception.

Are my shared files stored permanently on the cloud server?

It depends on the platform's retention policy. Typically, files shared via online services are stored securely in your cloud account until you manually delete them, unshare the link, or until the link's expiration date passes.
