Hash text or drop files to verify their content fingerprints. Watch how renaming keeps the fingerprint identical, while modifying a single character changes it entirely. Everything runs in your browser.
A file name is just a metadata label. Content-based ingestion pipelines hash the file's bytes to compute a content fingerprint. If the file is revised or corrected under the same name, the fingerprint changes. If a copy is uploaded under a new name, the fingerprint stays identical.
