Frequently asked questions
- What metadata formats are supported?
- SnapOtter handles ID3v1 and ID3v2 tags for MP3 files, Vorbis comments for FLAC and OGG, and MP4 atoms for M4A and AAC. All editing runs locally on your server.
- Can I strip all metadata from a file?
- Yes. You can remove all tags and embedded images in one action, which is useful for privacy before distributing files. Processing happens entirely on your self-hosted instance.
- Will editing metadata change the audio quality?
- No. Metadata editing only modifies the tag containers without touching the audio stream, so quality remains identical. Your files stay on your own network throughout the process.
