How private is this?
Encryption runs in your browser. The server only stores the encrypted blob — it never sees your plain text or password.

Mensaje seguro
Bloquea un texto corto con contraseña antes de enviarlo. El destinatario necesita la misma contraseña para leerlo en el navegador.
Security mode: local-only encryption
Encryption/decryption runs in your browser. Raw text and password are never sent to our server by this tool.

SenderPassword strength: Weak (recommended: 12+ chars)
Decrypt
ReceiverFor sensitive payment data, share password on a separate channel (never same chat).
Send a password-protected message online
Encrypt short text with a password before sending it. The recipient needs the same password to read it in their browser — no account, no server-side decryption.

Before you upload to Secure Encrypted Message
Check the file you are about to process, especially when it contains contracts, IDs, invoices, payroll details, legal drafts, school records, or client information. FileLumo is designed for quick no-signup workflows, but the safest document workflow still starts with choosing the right file and keeping an untouched original copy.
- Keep a master copy before editing, compressing, converting, or protecting a document
- Remove pages you do not need to share before uploading sensitive packets
- Use a clear filename for the downloaded result so drafts and final copies do not get mixed up
Privacy, limits, and output quality
Most PDF jobs are simple, but edge cases happen: very large scans, unusual fonts, password-protected files, embedded images, and old PDF versions can change the output. After processing, open the result once before sending it to a client, school, court portal, or upload form. Server-side workflows use TLS in transit. FileLumo does not store your files — download your result to keep a copy.
- Use medium or balanced settings first when quality matters more than the smallest possible file
- For strict upload limits, compare the final file size against the portal requirement before submitting
- For confidential documents, review your organization policy before using any third-party online tool
Frequently asked questions
What if I lose the password?
There is no recovery option. Without the password, the encrypted message cannot be decrypted by anyone.
Is secure messaging free?
Yes, free and no signup needed.
How long are messages stored?
Encrypted payloads auto-expire based on retention settings — typically a short window so leftovers are not stored.
