Kira Lock

Encrypt and decrypt files and folders locally with password-protected .klf archives.

Kira Lock protects files and folders by creating encrypted .klf archives directly in your browser. Select individual files or entire folders, choose whether to compress their contents, and protect the archive with a password. Folder paths are preserved so files can be restored with their original structure. Encryption and decryption are performed locally on your device. Kira Lock does not require an account, does not use remote servers to process your files, and does not upload selected content to external services. Main features: • Encrypt individual files and entire folders • Protected .klf archive format • Preserve and restore the original folder structure • Automatic, forced, or disabled compression • AES-256-GCM encryption • Locally generated passwords • Streaming processing to reduce memory usage • No account required • No file uploads to remote servers • System, light, and dark themes Important: Kira Lock does not store archive passwords and cannot recover them. Keep your password in a safe place: without it, encrypted content cannot be restored.
