Files are processed using ArrayBuffer manipulation. No canvas redraw, no re-encoding, no quality loss. Binary metadata segments are removed and file data is preserved byte-for-byte.
- All processing happens in your browser via client-side JavaScript
- No files are uploaded to any server
- No tracking, no analytics, no cookies
- The source code is open and auditable
- Video: fragmented MP4 (fMP4) is not supported.
- HEIC metadata preview may not display in all browsers (stripping still works).
