Because there was no AES encryption tool that was complete, free, usable without an account, and 100% client-side. Most encryption websites send your data to their servers — which defeats the purpose of encryption. We wanted a truly secure, truly private tool where you keep exclusive control of your keys.
"I encrypt all my client files with this tool before storing them on the cloud. Fast, reliable, and 100% local."

"I use it to encrypt my personal notes before syncing. Knowing everything stays client-side is reassuring."

In a world where data leaks are commonplace, encrypting your sensitive information is no longer an option — it's a necessity. Whether you're a developer, business owner, journalist, or individual, AES encryption lets you protect your passwords, credentials, private messages, personal notes, and confidential documents from unauthorized access.
Contrary to popular belief, AES encryption isn't just for cybersecurity experts. With our tool, simply enter a password and your text to get encrypted output that's impossible to decrypt without that same password. AES-256-GCM offers brute-force resistance of 2^128 operations — estimated cracking time of several billion years with current computing power.
The tool uses the Web Crypto API (SubtleCrypto) native to all modern browsers. This API implements cryptographic algorithms directly in the browser, no plugin or network call needed. Here's what happens when you click "Encrypt":
A random 16-byte salt is generated, along with a 12-byte initialization vector (IV). Your password is derived via PBKDF2 with SHA-256 over 600,000 iterations to produce a robust AES key. Finally, the text is encrypted with AES-GCM, producing ciphertext + an authentication tag. The salt, IV, and ciphertext are concatenated and Base64 or Hex encoded.
There are many AES encryption tools online. We tested the 7 main ones (AESOnline, Cryptii, Devglan, Browserling, CyberChef, AnyCript) on 12 objective criteria: encryption quality, available options, privacy, price, and advanced features.
Our main advantage is high-iteration PBKDF2 (600,000 rounds) versus often much lower values from competitors, plus fully offline mode once the page loads. Where AESOnline sends your data to a server (defeating the purpose of encryption) and Devglan doesn't offer AES-128-GCM, Volade does everything, every time, without compromising security.
With 12 key features, our tool surpasses all tested competitors. PBKDF2 at 600,000 iterations, offline mode, AES-256 and AES-128, file export — all free and without an account.

Unlike online encryption sites that receive your plain text on their servers (making encryption pointless), our tool processes everything locally via the Web Crypto API. The password, text, and derived key stay in your browser's memory. Verifiable in dev tools — Network tab.
The choice between AES-256 and AES-128 depends on your security requirements. AES-256 uses a 256-bit key, offering theoretically higher security margin. In practice, AES-128 is already considered unbreakable with current technology — it would take billions of years to brute force.
| Characteristic | AES-128-GCM | AES-256-GCM |
|---|---|---|
| Key size | 128 bits | 256 bits |
| Brute-force resistance | 2^64 opérations | 2^128 opérations |
| Performance | Fast (standard) | ~40% slower |
| Use case | Daily use, standard files | Ultra-sensitive data, compliance |
| Volade recommendation | Excellent for 99% of uses | Recommended by default |
In practice, AES-256-GCM doesn't provide significant security gains for most daily use cases, but it has become the default standard in the industry. We recommend it for maximum compatibility and comfortable security margin.
