What is this tool?
An AES File Encryptor is a powerful security tool that locks your files with military-grade encryption, making them completely unreadable to anyone who doesn't have your password - protecting sensitive documents, photos, financial records, and personal files from unauthorized access. Think of it like putting your files in an unbreakable digital safe that only you can open with your unique password. When you encrypt a file, the tool scrambles its contents using AES-256-GCM encryption (the same technology used by governments and banks to protect classified information), transforming your readable file into an encrypted .aes file that appears as random data to anyone trying to open it.
Our AES File Encryptor supports files up to 100MB and uses advanced security features including PBKDF2 key derivation with 100,000 iterations (which makes password cracking extremely difficult) and authenticated encryption (which detects if anyone tries to tamper with your encrypted files). The tool gives you complete control - choose your own password, encrypt your file in seconds, and decrypt it later when you need access. Everything happens directly in your browser using the Web Crypto API, meaning your files never leave your device and are never uploaded to any server.
Whether you're protecting confidential business documents, securing personal financial records, encrypting sensitive photos, or storing private information on cloud services, AES encryption provides professional-grade protection that keeps your data safe from hackers, data breaches, and unauthorized access. Students protecting research data, business owners securing client information, and anyone who values privacy can easily encrypt files without requiring technical knowledge. The tool includes a built-in password strength checker and can even link to our Password Generator to help you create strong encryption passwords.
