Local by design
Every computation — encryption, hashing, encoding, parsing — runs in your browser using WebCrypto and the platform's built-in Intl APIs. Nothing is uploaded, because there is no backend to receive it.
About Encrypt-Decrypt
Encrypt-Decrypt is a free, static, browser-local toolbox for practical data transformation and cryptography workflows — built for developers who need a quick, trustworthy answer without creating an account or wondering where their input went.
How it works
Honest boundaries
Client-side crypto is convenient, not a substitute for audited infrastructure. Verify outputs independently before using them in production, security-sensitive, or regulated workflows.
Fast by default, free forever
Static export, no accounts, no submit buttons — results appear as you type.
What's inside
Encrypt & decrypt
Protect, open, and safely share sensitive text.
Encode & convert
Move between common text, byte, and data representations.
Hash & verify
Create digests and compare values locally.
Inspect
Read tokens and structured payloads without uploading them.
Format
Make developer data readable and valid.
