KillMetadata, a browser-based metadata cleaner that shows its limits

Why it surfaced

This is a privacy utility with a concrete, inspectable workflow: detect the file format, explain what will change, create a separate cleaned copy, and rescan the result. Its most credible detail may be the refusal to promise a fantasy “100% metadata-free” outcome, especially for partially covered HEIC, HEIF, and AVIF files.

KillMetadata removes supported EXIF, GPS, author, date, and media metadata from photos, documents, video, and audio without uploading the files.
