Frequently Asked Questions

Do you store or keep my audio files?

No. Your audio files are not stored permanently.

When you upload a file, it is used only for processing — reading metadata, applying your changes, and preparing the updated file for download. After the process is complete, the file is not kept or saved for long-term storage.

This approach ensures your privacy and security. Your audio files, metadata, and cover images remain under your control and are not shared with third parties.

Because everything works directly in your browser or through temporary processing, you can safely edit ID3 tags and audio metadata without worrying about your files being stored or reused.

What are ID3 tags and audio metadata?

ID3 tags are a type of metadata stored inside MP3 files. They contain information about the audio track, such as title, artist, album, genre, year, track number, comment, and cover image.

Other audio formats like FLAC, OGG, and M4A also store metadata, but they use different tagging systems instead of ID3. Despite these technical differences, the purpose is the same — to describe and organize audio files.

When you open a file in a music player, the information you see — track name, artist, album artwork — comes from this embedded metadata, not from the audio itself. This allows players to organize your library and display content correctly.

Can I edit audio tags without installing software?

Yes. You can edit ID3 tags and audio metadata directly in your browser without installing any software.

Just upload your file, update the metadata fields, add or replace cover art if needed, and download the updated file. This works for MP3, FLAC, OGG, and M4A formats.

This is especially useful if you want a fast and simple way to fix metadata on any device, including laptops, tablets, and mobile phones.

How do I fix incorrect audio metadata?

To fix incorrect metadata, upload your audio file and review the existing tags. Then update any incorrect or missing fields such as title, artist, album, genre, year, track number, comment, or filename.

Incorrect metadata often appears after downloading files from different sources, converting formats, or transferring files between devices. Fixing metadata helps your music library stay clean and properly organized.

Why are my tags not showing in my player?

Tags may not appear correctly for several reasons. The file may have missing or corrupted metadata, the player may not refresh its library immediately, or the cover image may not be embedded properly.

In many cases, saving the file again with updated metadata solves the issue. It can also help to re-add the file to your player or refresh the media library.

Can I change the cover art of an existing audio file?

Yes. You can replace the cover art of an existing file by uploading a new image and saving the updated version.

This works for MP3 (ID3) as well as other formats like FLAC, OGG, and M4A. You can update low-quality, incorrect, or missing artwork with a new image.

Will editing tags affect audio quality?

No. Editing tags or metadata does not change the actual audio content of the file.

Only the descriptive information — such as title, artist, album, and cover image — is updated. The sound quality remains exactly the same.

What is the best image size for cover art?

Square images usually work best because they display correctly across most music players, apps, and devices.

A high-quality square image ensures consistent appearance. Extremely small images may look blurry, while very large images can unnecessarily increase file size.

Can I rename my file based on tags automatically?

Yes. You can rename your file based on metadata, for example using a format like artist-title.mp3.

This helps keep filenames consistent with the embedded metadata and makes files easier to organize, search, and manage outside of music players.

Which devices support audio metadata and cover art?

Most modern devices and media players support audio metadata and embedded cover art.

This includes smartphones, tablets, computers, car audio systems, smart TVs, and portable music players. Properly structured metadata improves compatibility and ensures correct display across different platforms.
