Why is Browser-Based Encryption Better?
Traditional online encryption tools require you to upload your sensitive file and your password to a third-party server. This exposes your data to potential interception, logging, or mishandling. Our tool eliminates that risk entirely. By using the powerful `crypto-js` library, all encryption and decryption operations run directly inside your browser. Your data never leaves your computer, offering the same level of security as an offline desktop application but with the convenience of a web tool.
