Generate MD5, SHA-1, SHA-256, SHA-384, and SHA-512 hashes from text or files. Uses the Web Crypto API for SHA hashes and a pure JavaScript implementation for MD5. Compare two hashes instantly.
LevnTools Hash Generator lets you format, validate, and transform your code directly in your browser. Everything runs locally in your browser — your code and data never leave your device. Unlike cloud-only alternatives that require uploads and accounts, this tool is completely free with no usage limits or watermarks. It is designed for developers debugging API responses, DevOps engineers working with configuration files, students learning data formats — anyone who needs a fast, reliable developer tool without the overhead of installing software. Just open the page and start working.
Hash Generator is used by a wide range of people. Explore how different groups use this tool:
Format, beautify, minify, and validate JSON with syntax highlighting.
Encode and decode Base64 with UTF-8 support and file-to-data-URI.
Encode, decode, and parse URLs with editable query parameters.
Convert text to camelCase, snake_case, kebab-case, and 7 more.
Convert between metric and imperial length units.
The tool generates five hash types simultaneously: MD5 (128-bit), SHA-1 (160-bit), SHA-256 (256-bit), SHA-384 (384-bit), and SHA-512 (512-bit). SHA hashes use the browser Web Crypto API; MD5 uses a pure JavaScript implementation.
Yes. Switch to "File Hash" mode and drag-and-drop a file or click to select one. The tool reads the file in your browser, computes all five hashes, and displays them. Large file MD5 computation runs in a Web Worker to keep the UI responsive.
Switch to "Compare" mode and paste two hash strings. The tool performs a case-insensitive comparison and tells you whether they match. This is useful for verifying file integrity after a download.
Yes. All hashing is done locally in your browser using the Web Crypto API and a JavaScript MD5 implementation. No data — text or files — is ever sent to a server.
No. MD5 is considered cryptographically broken and should not be used for passwords or security purposes. Use SHA-256 or stronger algorithms for security. MD5 is still useful for checksums and non-security file verification.
