What This Tool Helps You Do
File Encrypt/Decrypt helps you encrypt and decrypt files using AES-GCM via WebCrypto. It is designed for security-conscious users checking secrets, hashes, permissions, passwords, certificates, and safe sharing workflows who need encrypt file, decrypt file, and aes encryption without switching into a heavier toolchain than the task actually requires.
Use these tools for privacy-sensitive browser workflows such as hashing, scanning, generating keys, cleaning metadata, and evaluating risk. On this page, the focus is encrypt file and decrypt file. For this tool, the main processing happens in your browser tab and the output is prepared on the same device. That makes it a better fit for quick edits, conversions, cleanup, and review work that should stay close to the source file or pasted data.
