Encrypt File Online

Encrypt File Online allows AES-256 encryption of any file size directly in your browser using WebCrypto, ensuring files never leave your device. It operates with a zero-trust model, requiring no servers, accounts, or uploads, and is deployed on Cloudflare Workers. Users simply drag a file, enter a password, and receive an encrypted output, with decryption following the same process. Built with React, Zustand, Tailwind, Hono, and Cloudflare Workers, it is open-source for transparency and is completely free, without tracking or logging user data.
