CocoDoc adds value to the privacy and the security of your files. Whenever a file is uploaded on the servers, they go through secure SSL connections. These files are only stored temporarily, and the servers permanently remove them within an hour.

Choose a strong password for your PDF, and CocoDoc uses modern encryption methods to keep the imported file safe. We recommend that you use a strong and secure password. The password can be a non-dictionary word containing 7 characters or more along with uppercase letters, lowercase letters, numbers, and symbols.

We believe that security should not be limited to a single medium. It is why we have made our web application compatible with a wide range of platforms that include Windows, Linux, and macOS. It ensures you can encrypt files from anywhere through any compatible device.

A secure and strong password should be used to prevent unauthorized access to your important data within the file. Our password encryption ensures that no one can crack your password within a realistic timeframe using a regular computer.

Encrypt your files with ease as no additional software is required to secure your files. Everything is done on the cloud. Simply upload your file from any device, add a secure password to your PDF, and your encrypted PDF will be ready to download.

Securing your file through strong encryption techniques doesn't require any software to be installed on your device. CocoDoc is browser-based. Moreover, the encryption process happens entirely on the cloud. Once it completes the process, the password is instantly deleted from the cloud. Besides, the file is also removed after an hour.
