Supported formats
Media input and output
Same format out
The download keeps the original file type, so an MP3 stays MP3 and an MKV stays MKV.
Tags and cover art
Edit common title, artist, album, genre, track, disc, composer, comment, and cover art fields in the browser.
No cloud upload
Your media stays on your device while the browser prepares the download.
Frequently asked questions
Will the output format change?
No. The tool keeps the same file type as your input. For example, MP3 downloads as MP3, and MKV downloads as MKV.
Which metadata fields can I edit?
You can edit title, artist, album, album artist, year, track, disc, genre, composer, and comment fields.
Can I add or remove cover art?
Yes. You can add, replace, or remove cover art, and existing artwork is preserved when you only edit text tags.
Will audio or video quality change?
Usually no. The tool preserves the existing media streams where possible and only updates text tags.
Are my files uploaded?
No. Processing runs in your browser, so your media file is not uploaded to a server.
