What it calculates
Generate MD5, SHA-1, and SHA-256 hashes from any text.
Whether you think of it as a "hash generator" tool, a "md5 generator or sha256 generator" tool, or simply the Hash Generator, this page covers the same calculation.
You can find it at any time on the Hash Generator page, where the calculator sits above a full explanation of the method it uses.
Tips for an accurate result
Close other heavy browser tabs first if you're working with a very large file — browser-based processing shares your device's memory.
Check the output file's size and format before relying on it elsewhere — some destinations have their own size or format limits.
Everything here runs locally in your browser — there's no upload step, so it works offline once the page has loaded.
When quality matters, compare the output against the original at full size before deciding a setting was correct.
