FileFlip uses WebCrypto API (AES-GCM encryption) safely in your web browser. When you encrypt a file, your password and the file contents never leave your device. Only you keep the key.
Frequently asked questions
Is this safe?
Yes, we use the browser's native WebCrypto API. Data is never uploaded to any server.
Can you recover my password?
No. The encryption is 100% offline. We have zero knowledge of your password.
Are there file limits?
Since it runs locally, you can encrypt files up to your device memory limits (usually a few hundreds MBs).
