What this tool does
Load local audio files to read their metadata and technical properties, then edit title, artist, album, album artist, track number, disc number, year, genre, comment, composer, and embedded artwork. Clear any field independently. The tool shows a per-file change preview before saving and can apply checked batch changes across supported files.
Supported formats and unsupported files
Read and write support covers MP3, FLAC, and WAV while preserving the original audio bytes. MP3 writes ID3v2 tags; it reads ID3v1 values only when the parsed ID3v2 data has no title and no artist. FLAC uses Vorbis comment and picture blocks, and WAV uses the RIFF LIST/INFO chunk.
Other formats can remain in the queue for filename and size reference, but they cannot be edited or saved as edited outputs. They are skipped during writing. A downloaded ZIP may still include their entry in manifest.json, but it does not contain an edited file for them.
What the technical preview shows
Technical tags (read-only) shows the format, codec, duration, sample rate, channels, bitrate, and bit depth. MP3 values are estimated by scanning for an MPEG frame, so duration and bitrate-related values may be estimated or unavailable.
Edit metadata and artwork
Edit each metadata field or use its Clear control. In the artwork panel, use Replace to choose a local image or Clear artwork to remove the embedded image. Replacement artwork is embedded as-is without re-encoding. Untouched artwork is carried through unchanged.
Validation and change preview
Track and disc numbers are checked as whole numbers in a plausible range. Year is checked as a four-digit value from 1000 to 2100. Text values over 1000 characters trigger a warning and are truncated during save, including batch edits. Warnings do not prevent saving. Review the per-file preview to compare field values before and after the edit and see artwork changes.
Batch editing and queue controls
Use Add more files to extend the queue and the remove buttons to prune it. In Batch edit, check the fields to change, enter shared values or select Clear, and checked batch fields update supported queued files automatically. Changes apply to supported files; each file keeps its own values and preview.
How to use the Audio Tag Editor
- Drop files onto the drop zone or click browse files.
- Edit the selected file's fields, or use Clear beside a field.
- Use Replace or Clear artwork if needed.
- Review the change preview and validation warnings.
- Wait for the automatic save, then use Download edited file.
- For the queue, apply any batch changes, wait for the automatic queue save, then use Download all (ZIP + manifest).
Export and manifest
A saved file can be downloaded directly. For the queue, the ZIP includes manifest.json. The manifest lists every queued file, its format, support status, changed fields with before-and-after values, artwork changes, and warnings.
Limitations and privacy
Processing happens locally in the browser, and the implementation contains no upload behavior. Saving creates a new file; it does not modify the original. The tool changes metadata containers while preserving the original audio bytes. It does not transcode, change bitrate, normalize volume, resample, or edit waveform content.
Frequently asked questions
Which audio formats can I actually edit and save?
Full read and write support covers MP3 (ID3v2 tags; ID3v1 values are read only when parsed ID3v2 data has no title and no artist), FLAC (Vorbis comment and picture blocks), and WAV (RIFF LIST/INFO chunk). Other formats can remain in the queue for reference, but they are not saved as edited outputs.
Does this tool touch the actual audio data?
No. The tool locates and rewrites only the metadata container - the ID3v2 tag, the Vorbis comment/picture blocks, or the RIFF INFO chunk - and copies every audio byte through unchanged. It does not decode, transcode, resample, normalize volume, or otherwise touch the waveform.
How does batch editing work?
Queue multiple files, then use the batch panel to check which fields you want to change, type a value (or check Clear), and apply it across every supported file in the queue. Each file keeps its own per-file preview so you can confirm exactly what changed before saving.
What does the manifest contain?
When you download a ZIP of multiple edited files, a manifest.json is included listing every queued file, its format, whether it was supported, every changed field with its before/after value, whether artwork changed, and any warnings - a written record of exactly what was edited.
