🦭 Seal Transfer

Seal Transfer is a lightweight, browser-based encryption tool that lets you securely seal files with a password — entirely on your device.

Files are encrypted using modern cryptography (AES-256-GCM) and never uploaded, stored, or transmitted. Only someone with the correct password can open them.

🔐 Encrypt a File

Select a file and protect it with a password. The encrypted .seal file is downloaded locally and contains no readable metadata.

🔓 Decrypt a File
