Open any audio file — without uploading it

Drop a common audio format and OmniViewer inspects the file, edits its supported metadata, cleans tags across several tracks at once, and builds a temporary local playlist. Everything runs in your browser — no upload, no server.

Formats with a dedicated toolkit

WAV, FLAC, OGG and AAC open in the universal viewer with a byte-exact hex view and, where the container allows, metadata and batch tag-cleaning. Because the file is read locally, even a long, multi-gigabyte recording opens instantly and privately.

FAQ

Is my audio file uploaded anywhere?

No. OmniViewer is a static page with no server-side processing: your audio is read directly by your browser and never leaves your computer.

Which audio formats are supported?

MP3 has a dedicated toolkit — playback, ID3 tag and album-art editing, conversion to WAV/FLAC/Opus, bitrate and frame stats, and a hex view. WAV, FLAC, OGG and AAC open in the universal viewer with a hex view and, where possible, metadata and batch tag-cleaning. Format is detected from the content, not the extension.

Can I edit tags or convert the audio?

For MP3, yes: edit the ID3 tags and cover art and download a re-tagged copy with the audio never re-encoded, or convert to WAV, FLAC or Opus with ffmpeg compiled to WebAssembly — all locally.
