Encrypt Files and Text in Your Browser
AES-256-GCM runs on your device. No upload, no account. Site statistics are cookie-free and off by default.
Pick a task, not a toolkit
Each shortcut opens the right tool with the right mode already selected. No account, no upload.
Encrypt a file
Choose a file, set a passphrase and download the encrypted result. Nothing is uploaded.
Encrypt a fileEncrypt text
Paste a message and encrypt it in the browser before you send it anywhere.
Encrypt textHash a value
Create SHA-256, SHA-384 or SHA-512 digests locally, without sending the input.
Open hash toolVerify it yourself: open DevTools, switch to the Network tab, encrypt a test note and confirm that no request carries your text. See the full verification steps
Why Your Data Stays Private With Us
Every design choice we make starts with one question: can we build this without ever touching your unencrypted data?
Encryption Happens on Your Device
All encryption uses the Web Crypto API built into your browser. Your data is encrypted before any network request happens. We never see the original.
You Keep the Keys
Encryption keys are derived from your passphrase and stay on your device. They never travel over the network. Without them, your encrypted data is just noise.
Standard Algorithms, No Secrets
We use AES-256-GCM for encryption and PBKDF2 for key derivation — publicly reviewed standards. Our implementation is documented, not hidden.
Designed to Collect Nothing
No account required. No personal information needed. The tools do not track your encryption activity, and site statistics are aggregate, cookie-free, and off by default. We built the service so it works without collecting your data.
Free Encryption Tools, No Strings Attached
All tools run in your browser. Nothing leaves your device unless you choose to share encrypted output. Free to use. No account, no upload, no ad-tech.
- AES-256-GCM encryption for files, text, PDFs and photos
- Runs client-side — your device does the work, not our servers
- No account or signup — start immediately
- Completely free to use
- Works offline once the page loads
How Zero-Knowledge Encryption Works
You Input Data
Type text or upload a file in your browser. Nothing has left your device yet.
Your Browser Encrypts It
Using AES-256-GCM via the Web Crypto API, your data is encrypted locally. Your key never leaves your device.
Only You Can Decrypt
Without your key, the encrypted output is meaningless. Not even we can read it.
Built for people who would rather not upload
In a world of data breaches and surveillance, we built something different — tools that respect your privacy by design, not by promise.
Zero-Knowledge by Architecture
There is no server-side copy: encryption happens in your browser before anything could be sent.
No Hidden Data Collection
No telemetry in the tools themselves; our hosting provider processes ordinary request logs for security, never to profile you. Your encryption activity is your business, not ours. Site-wide statistics are aggregate, cookie-free, and off by default.
Open standards, inspectable behavior
We use public, peer-reviewed cryptography. Our implementation is transparent — you can inspect network traffic in your own browser and confirm that nothing readable is sent.
Reference Material for Security Decisions
The parts vendors usually skip: lost keys, retention windows, legal boundaries, and how the encryption models actually differ.
Key Lost
Why a zero-knowledge design has no reset path, and what to arrange before a key goes missing.
Choosing Tools
A vendor-neutral checklist for judging where encryption runs and who holds the keys.
Data Retention
What retention means when nothing is uploaded and the copy lives on your device.
Encryption & Law
Where encryption meets export controls, internal policy, and record-keeping duties.
Client-Side vs E2E
How client-side and end-to-end designs differ in key custody and threat coverage.
AES-256 Modes
What AES-256 protects on its own, and why the mode and the passphrase carry the rest.
