Strip hidden metadata from your files.
Photos, videos, audio, and PDFs contain hidden data — GPS coordinates, camera specs, author names, and timestamps. Sanitizr strips them instantly in browser memory before you post or share.

What is file metadata?
When you snap a photo, record video, or create a document, hidden data tags are attached: GPS coordinates, device model, author name, creation time, and software used.
Are files sent to any server?
Never. Images use Canvas re-encoding, videos/audio use FFmpeg WebAssembly, and PDFs use pdf-lib — all running locally in your browser with zero network requests.
How does video/audio work?
FFmpeg runs as WebAssembly (~25MB, loaded once). It strips container metadata using stream copy — no re-encoding, so quality is identical and processing is fast.
What about PDFs?
PDF Info dictionary fields (title, author, subject, creator, producer, dates) are cleared. The document content and formatting remain completely untouched.
Will file quality change?
No noticeable difference. Images are re-drawn at 95% quality. Videos, audio, and PDFs use stream copy or metadata-only editing — content is bit-identical.
