Private local processing
The browser reads your input and computes checksums locally. No upload endpoint is used for this tool.

Developer utility
Hash API payloads, sample strings, signatures and fixtures without sending sensitive text to a server.
Frequently Asked Questions
Are my files uploaded when I generate a hash?
No. Text and files are read by JavaScript in your browser. The content is not sent to Convertr servers.
Which algorithms does this hash generator support?
The tool supports SHA-256, SHA-1 and MD5. SHA-256 and SHA-1 use the browser Web Crypto API; MD5 runs as local JavaScript for compatibility checks.
Should I use MD5 for security?
No. MD5 is included for legacy checksums and file comparison only. Use SHA-256 for stronger integrity checks.
