Frequently asked questions

Quick answers about file privacy, processing modes, formats, and device support.

You can view and edit metadata tags for MP3 (ID3v1 & ID3v2.3/ID3v2.4), FLAC (Vorbis comments), M4A/AAC (iTunes metadata), and WAV (RIFF INFO tags).

No! Elixuvo utilizes lossless stream copying (`-c copy`). Only the metadata header and container tags are updated, meaning your audio streams remain 100% bit-perfect without any quality degradation.

Simply drag and drop an image (JPG, PNG, or WebP) into the Album Artwork box in the editor, or click to browse. The image will be embedded directly into the audio file container.

Yes! Many modern car stereos, smartphones, and media players (Apple Music, Spotify, VLC) read ID3 tags rather than filenames. Setting proper Title, Artist, and Album tags ensures your music organizes cleanly.

Zero. Both ID3 tag parsing and file rewriting occur 100% locally on your computer inside your browser's WebAssembly sandbox. Nothing is ever uploaded or stored externally.
