How burnbag works

Our zero-knowledge encryption ensures your files remain private and secure from creation to delivery

Create your burnbag

Start by creating a new burnbag in your secure dashboard. Upload files, add messages, and set expiration parameters.

1

Log in to your dashboard and click "Create BurnBag"

2

Upload files and add an optional message

3

Set expiration time and burn-after-reading options

Zero-Knowledge Architecture

Your files and messages are encrypted in your browser when you upload them, and we never see the encryption key that unlocks them. We never see anything.

Unique Link and Key

After you've created a burnbag, you get a unique URL and encryption key which is required to view your messages or download the files.

Burn After Reading

You have the choice to burn the file on first access, ensuring your sensitive data doesn't linger longer than necessary.

About burnbag

Our mission is to make secure file sharing accessible to everyone

Our Story

Burnbag was born from a simple realization: in today's digital world, sharing sensitive files securely shouldn't be complicated or expensive.

Founded by a team of privacy advocates and security engineers, we set out to create a solution that puts privacy first. We believe that everyone deserves access to secure communication tools, whether you're a journalist protecting sources, a lawyer handling confidential documents, or simply someone who values their privacy.

Our zero-knowledge architecture was designed from the ground up to ensure that even we can't access your data. Your files are encrypted in your browser before they ever reach our servers, and only the recipient with the correct decryption key can access them.

Why Secure File Transfer Matters

In an era of increasing digital surveillance and data breaches, the way we share sensitive information matters more than ever. Standard email attachments, cloud storage, and messaging apps often lack the security needed for truly confidential files.

When you send a file through conventional methods, it often passes through multiple servers, each representing a potential point of vulnerability. Your data may be stored indefinitely, analyzed for advertising purposes, or vulnerable to breaches.

Burnbag changes this paradigm. With client-side encryption, ephemeral storage, and self-destructing links, we ensure your sensitive data remains private, is available only to intended recipients, and doesn't persist longer than necessary.

Our Core Values

Privacy by Design

We build privacy into every aspect of our service. From zero-knowledge encryption to minimal data retention, privacy isn't an afterthought—it's our foundation.

Simplicity & Accessibility

Security shouldn't be complicated. We've designed burnbag to be intuitive and straightforward, making secure file sharing accessible to everyone, not just security experts.

Transparency & Trust

We're open about how our service works and what we do with your data. We believe that trust is earned through transparency and consistent delivery on our promises.

Our team is dedicated to building the most secure, user-friendly file sharing service available. We're constantly improving burnbag based on user feedback and evolving security best practices.
