Generate MD5, SHA-1, SHA-256, SHA-512 hashes. Free, private, runs in your browser.
A cryptographic hash function takes any input — a string, file, or data block — and produces a fixed-length, unique fingerprint (called a digest). Common algorithms include MD5, SHA-1, SHA-256, and SHA-512. Hashes are one-way: you can generate a hash from data, but you cannot reverse-engineer the original data from the hash.
Hashes are essential for verifying data integrity (confirming a downloaded file hasn't been tampered with), storing passwords securely, generating checksums, creating unique identifiers, and validating API signatures. Developers and security professionals use hash generation daily for testing, debugging, and verification workflows.
Enter any text and Convertful instantly computes its hash using your chosen algorithm — MD5, SHA-1, SHA-256, or SHA-512. The tool uses the Web Crypto API and JavaScript implementations running entirely in your browser. No data leaves your device.
Yes. All hashing is performed locally in your browser using standard cryptographic libraries. Your input text is never transmitted to any server — critical when hashing sensitive data like passwords or API keys.
