Key Benefits
100% Private & Secure
All hashing is performed entirely in your browser using the Web Crypto API. Your data never leaves your device or gets uploaded to any server.
Multiple Algorithms
Generate MD5, SHA-1, SHA-256, and SHA-512 hashes simultaneously. Compare outputs across algorithms with a single input.
Text & File Support
Hash any text input or upload files of any type. The file is read locally and processed in-browser using ArrayBuffer.
No Installation Required
Works directly in your browser. No software to download, no accounts to create, and completely free to use.
Frequently Asked Questions
Is my data sent to a server?
No. All hashing happens entirely in your browser using the Web Crypto API and JavaScript. Your text and files are never uploaded or transmitted anywhere.
What is the difference between MD5, SHA-1, SHA-256, and SHA-512?
They are different cryptographic hash algorithms with varying output lengths and security levels. MD5 produces a 128-bit hash, SHA-1 produces 160-bit, SHA-256 produces 256-bit, and SHA-512 produces 512-bit. SHA-256 and SHA-512 are considered the most secure for modern use.
Can I hash large files?
Yes. Files are read locally using the FileReader API. However, very large files may take longer to process depending on your browser and device capabilities.
Is MD5 still safe to use?
MD5 is considered cryptographically broken and should not be used for security purposes like password hashing or digital signatures. However, it is still commonly used for file integrity checks and checksums.
Can I switch between uppercase and lowercase hash output?
Yes. Use the uppercase/lowercase toggle to switch the hex output format. This is useful when you need to match a specific hash format for comparison.
