Audio Metadata Editor

View and edit the ID3 tags of an MP3, including title, artist, album, year, genre, track number, lyrics and cover art. Reads the existing metadata of other audio formats too, and saves a tagged copy of your MP3.

Everything runs locally in your browser. Your data never leaves your device.

Tags of MP3 files are editable. Other formats show their tags read-only.

Audio Converter

Convert audio files between MP3, WAV, OGG, FLAC and M4A. Drop in as many files as you like, pick the target format and bitrate, and download the results one by one or all at once.

Hash Generator

Hash text or a file with MD5, SHA-1, SHA-256, SHA-512, SHA-3, BLAKE2, BLAKE3, CRC32 and more, all computed live as you type. Compare against an expected checksum and copy any digest.

Checksum Validator

Verify a checksum online: drop a file, paste the expected checksum and see instantly whether they match. The hash type is detected from the checksum itself, covering MD5, SHA-1, SHA-256, SHA-512, BLAKE3, CRC-32 and more, and sha256sum lines or whole checksum files can be pasted as-is.

Data Compressor

Compress text or a file with gzip, deflate, brotli or Zstandard and see the size before and after, the compression ratio and how long it took. One click tries every method and recommends the smallest result.

Data Decompressor

Decompress gzip, deflate, brotli or Zstandard data from a file or pasted Base64 and read the result as text or download it. Detects the format from the magic bytes where possible, with a manual override.

Hex Viewer

Inspect any file or text as a hex dump with offsets, byte values and an ASCII column. Jump to an offset, search for bytes or text, select a range to see it decoded as integers and strings, and copy or download the dump.

Audio Inspector

See everything about an audio file: duration, format, codec, sample rate, bit depth, channels and bitrate, the embedded tags and cover art, plus measured peak and RMS levels and a waveform overview.

Audio Trimmer

Cut a section out of an audio file on a zoomable waveform timeline. Drag the start and end handles, play back just your selection, fade the edges if you like, and export the result as MP3, WAV, OGG, FLAC or M4A.

About the Audio Metadata Editor Tool

This tool shows and edits the metadata inside an audio file. Load an MP3 and every common ID3 tag is editable: title, artist, album, album artist, year, genre, track and disc number, composer, comment and lyrics. The cover art can be replaced with a new image or removed, and saving downloads a tagged copy. The audio itself is never re-encoded, only the tag block changes.

Other formats like FLAC, WAV, Ogg and M4A open read-only, so you can still inspect their tags and cover art. Writing works for MP3 only. To edit another format, convert it with the Audio Converter first and tag the result.

What you can do

Edit the ID3 tags of an MP3, from title and artist to lyrics.
Change or remove the cover art embedded in an MP3.
Add album art to an MP3 that has none.
Fix a wrong year, genre or track number in a music file.
Add tags to an untagged MP3 recording.
View the metadata of FLAC, WAV, Ogg and M4A files.
Save a tagged copy and compare its size with the original.

How to use the Audio Metadata Editor

1Drop in an audio file, or click to choose one.
2Edit the tag fields. A cleared field is removed from the saved copy.
3Replace or remove the cover art if you want a different image.
4Check the note on what carries over, then hit Save tagged copy.
5The tagged MP3 downloads right away, the original file stays untouched.

How saving works

Saving writes a fresh ID3v2.3 tag at the front of the file and copies the audio data over unchanged. Every field shown in the form is written back, along with common extras the file already carried, like BPM, copyright, publisher, ISRC and the compilation flag. An old ID3v1 tag at the end of the file is dropped, so an outdated title cannot resurface in players that still read it.

Some tags have no place in the rewritten header, for example ReplayGain loudness data, ratings and MusicBrainz identifiers. The tool lists exactly which of these your file carries before you save, so nothing disappears silently.

Why only MP3

Every format stores metadata differently. MP3 uses ID3 tags with a well tested browser writer, while FLAC, Ogg and M4A each need their own container rewrite, and no reliable browser writer exists for those. The tool therefore reads all common formats but writes MP3 only. The Audio Converter turns any supported file into an MP3 you can tag here, and the Audio Inspector digs deeper into a file's codec, bitrate and measured levels.

Credits

Open source does the heavy lifting in this tool. Thank you to:

music-metadata
A metadata parser that understands the tags of virtually every audio format.
browser-id3-writer
A JavaScript library that writes ID3v2 tags into MP3 files in the browser.
