Audio Metadata Editor lets you view and update the most common audio tag fields in one quick upload → edit → download flow. After you upload a file, the tool probes the container and codec, reads existing tags, and displays editable fields such as title, artist, album, album artist, genre, date/year, track number, disc number, and comment. When you click Update metadata, the backend writes your updated tag values into a new MP3 file for consistent playback compatibility and easy sharing. This is helpful when your music library has wrong titles, when podcast exports are missing artist/episode info, or when you want cleaner metadata for car stereos and media players. The tool includes a Sample input button so you can instantly see how tag detection and writing works. For power users, an optional AI Assistant can suggest clean, consistent tag values based on the filename and detected metadata, but it only runs when you explicitly request it and it never changes your file automatically.
Note: AI can make mistakes, so please double-check it.
Fix titles, artists, albums, and track numbers.
Free plan includes audio uploads up to 20MB. Paid plans unlock files up to 50MB.

Common questions about this tool
Upload your audio file, wait for the tool to detect existing tags, then edit fields like title, artist, and album. Click Update metadata to download a new MP3 with your updated tags written by the backend.
You can edit common metadata fields including title, artist, album, album artist, genre, date/year, track number, disc number, and comment. Fields left blank are treated as removed for the output file.
The tool exports an MP3 output for consistent metadata writing and compatibility. For most use cases this is acceptable, but if you need to preserve the original container and exact stream, use a dedicated tag editor for that format.
Different audio containers store tags differently. To keep results consistent across devices, the tool writes updated metadata into a new MP3 output that plays reliably in most apps.
When you click Suggest tags with AI, the tool sends only the filename and a compact summary of detected tags and technical info to a backend AI service. It returns suggested tag values and a short rationale, and you can review and edit them before applying updates.
Upload your audio file, wait for the tool to detect existing tags, then edit fields like title, artist, album, and year. Click Update metadata to download a new MP3 with the updated tags written on the backend.
Upload the file, edit the Artist field, and run Update metadata. The output download contains your updated artist tag and can be re-checked by uploading it again to confirm the change.
Enter the value in the Track field (for example, 1 or 01/12) and update metadata. Track numbers help albums sort correctly in many players.
This tool outputs a new MP3 for consistent tag writing and playback compatibility. For most everyday use, this is fine, but if you need to preserve the original container and stream exactly, use a format-specific tag editor.
Different apps and devices may prefer specific tag versions and supported fields. If tags do not appear, try keeping fields simple (title, artist, album, year) and re-download the updated MP3 to ensure the tags were written cleanly.

Learn what this tool does, when to use it, and how it fits into your workflow.
Audio metadata is the information that travels with an audio file: title, artist, album, year, genre, track number, and other tags that help media players display, sort, and search your library. When metadata is missing or messy, the same song can appear under the wrong artist, podcast episodes can show up as “Unknown,” and car stereos can group everything into one folder. This Audio Metadata Editor helps you view detected tags and write clean values in a fast, no-code workflow.
People often search for “edit MP3 tags online” or “change song info on iPhone” because metadata affects everyday playback. Most music apps use tags to build the artist and album views. Podcast apps display episode titles and dates. Even if the audio sounds perfect, bad tags make it harder to find, share, and archive your recordings.
Metadata also helps when you deliver audio to clients or platforms. A correctly tagged file looks more professional, especially when you send a voiceover pack, a demo reel, or a short music preview. If you are publishing, metadata can also help distinguish versions: “Mix v2,” “Clean edit,” or “Intro only.”
Audio formats store metadata differently. MP3 commonly uses ID3 tags. FLAC and OGG often use Vorbis comments. M4A uses MP4-style atoms. The same “Title” field may have different internal names depending on container. To keep results consistent and easy to use across devices, this tool writes updated tags into a new MP3 output.
If you upload a WAV, it may have little or no metadata in the first place. If you upload an M4A or FLAC that contains tags, the probe step will still display what is detected, but the downloaded file is an MP3 so it can carry standard tag fields and play reliably in most environments.
This editor focuses on the most common text fields that people search for when they want to “edit MP3 tags”: title, artist, album, album artist, genre, date/year, track number, disc number, and comment. These cover the majority of library organization needs. You can remove a value by clearing the field before you update.
Track and disc numbers are especially useful when you are tagging full albums. They prevent “Track 10” from appearing next to “Track 1” and keep multi-disc releases grouped correctly. Date/year helps with sorting and makes it easier to distinguish versions when you have re-releases or remasters.
The AI Assistant is useful when your filename contains the real information but tags are empty. For example, files named “Artist - Title (Remastered)” or “Episode 12 - Guest Name” often contain enough structure to suggest a title, artist, and album pattern. When you click Suggest tags with AI, the tool sends a compact payload to a backend service: the filename plus detected tags and basic file info. The AI returns suggested values and a short rationale, and you can still edit everything before writing the final output.
If you downloaded a track and it shows up as “Unknown Artist,” upload it, set the artist and title, and download the updated MP3 so your library groups it correctly. If you exported a podcast episode from an editor and the episode title is missing, set title, date/year, and comment so it displays clearly in players. If you are preparing a voiceover pack, standardize artist (talent name), album (project name), and track numbers so clients can navigate quickly.
Metadata editing is often paired with analysis and conversion. These tools can help before or after you edit tags:
