// How it works

Three steps. Zero uploads.

01
Type
Enter or paste your text — messages, notes, passwords, or any sensitive content.
02
Set password
Choose a strong password. This is the only key that can decrypt your text.
03
Encrypt
Your text is encrypted with AES-256 in your browser. Copy the encrypted output to share or store.
// Why this is different

Encrypt messages without trusting a server.

Most online text encryption tools send your plaintext to a server to encrypt it. That defeats the purpose. fwip encrypts entirely in your browser. Your original text is never transmitted to anyone.

fwip works differently. The processing engine runs entirely in your browser. Your text is read from your device, processed on your CPU, and the result is saved back to your device. No server is involved. We literally cannot see your file.

No server processing

Everything runs on your device using WebAssembly. Your file never touches a network.

No account required

Drop a file. Get a result. No sign-up, no email, no password.

No subscription

Free in the browser. $99 once for the offline bundle. That's it. Forever.

Works offline

The desktop version works with no internet connection at all.

Use it free in your browser. Own it offline for $15. No subscription. Your words. Your encryption.

// Questions

Frequently asked.

How do I encrypt text without uploading it?▾
Type or paste your text into fwip, set a password, and click Encrypt. The encryption runs entirely in your browser. Your plaintext is never sent anywhere.
How do I share encrypted text?▾
Copy the encrypted output and send it via email, chat, or any channel. Share the password separately (ideally through a different channel). The recipient uses fwip to decrypt with the same password.
What encryption does fwip use?▾
AES-256 via the Web Crypto API built into your browser. This is the same encryption standard used by banks and governments.
Can I decrypt text from someone else?▾
Yes. Paste the encrypted text into fwip, enter the password the sender used, and click Decrypt. The original text is restored.
What if I forget the password?▾
The text cannot be recovered. fwip has no server and no recovery mechanism. Store your password securely.
Is this actually secure?▾
Yes. Browser-based AES-256 via the Web Crypto API is cryptographically sound. The security depends on your password strength — use a long, unique password.
