On-device

Your selected media stays on this device. AudioFetcher loads its processing engine, reads the file in browser memory, and creates the result locally.

Temporary

Refresh or close the tab and the selected file and generated result leave browser memory.

Honest limits

Use a reasonably sized square image; very large artwork increases the MP3 file size.

How to use Add Cover Art to MP3

  1. 1

    Choose an MP3 already on your device. Keep the original as a backup.

  2. 2

    Under Cover image, select a JPEG or PNG you own or have permission to use. A modest square image is a useful starting point; check your player's requirements.

  3. 3

    Select Add Cover Art to MP3 and keep the tab open while the image is embedded.

  4. 4

    Download the new MP3, open that copy in your player, and refresh its library if the old artwork still appears.

What this tool changes

The tool copies the MP3 audio stream and embeds your JPEG or PNG as the front cover without re-encoding either. Choose JPEG if your player requires it. It does not search for artwork, restore audio quality, or change the original file.

Example: choose your own recording.mp3 and cover.jpg, run the tool, then download the resulting MP3. The picture travels inside the downloaded file, but display still depends on the player.

Need to correct titles too? Edit the tags without losing existing artwork. If artwork is missing, check the artwork troubleshooting guide.

Watch: add a cover, then edit the tags

A 33-second example: add a cover with this tool, then fix the title and artist with the MP3 tag editor. No account and no upload.

What size and format should the picture be?

MP3 album art not showing? Fix it free

  1. Open the downloaded copy, not the original. The tool creates a new MP3; your original file is unchanged.
  2. Check that the cover is really embedded. Renaming a file or putting a picture next to it does not add a cover. Open the new copy in a second player: if the cover shows there, the file is fine and the first player is the problem.
  3. Clear the player's cache. Music apps, Windows File Explorer and phones remember old artwork. Remove the track from the library and add it again, or rescan the folder. On Windows, clearing thumbnails in Disk Cleanup makes File Explorer redraw the icons.
  4. Old device or car stereo? Try one modest square JPEG, for example 500 by 500 pixels and under about 500 KB. The tool writes ID3v2.3 tags, the version older Windows and car stereos read best, but no image size works on every device, so check its manual.
  5. A cover.jpg in the folder is not the same thing. Some players show a folder image instead of the embedded one. The embedded picture travels with the file when you copy it to a phone or USB stick.

More fixes: cover art not showing.

How album art is stored inside an MP3

An MP3 keeps its cover in the ID3 tag at the start of the file, in an attached-picture frame (APIC) marked as the front cover. It is metadata, separate from the audio frames, which is why adding or replacing a cover never changes how the song sounds.

Other ways to add album art

This tool handles one MP3 at a time and works on any computer or phone with a modern browser. For a whole music library:

Add Cover Art to MP3 questions

Does Add Cover Art to MP3 upload my file?

Your selected media stays on this device. AudioFetcher loads its processing engine, reads the file in browser memory, and creates the result locally.

What should I know before using Add Cover Art to MP3?

Use a reasonably sized square image; very large artwork increases the MP3 file size.

Does adding cover art change the audio quality?

No. The audio is copied into the new file as it is, without re-encoding. Only the picture is added, so the file grows by roughly the size of the image.

Will it replace the cover the MP3 already has?

Yes. The new file gets your picture as its front cover in place of any picture already embedded. Your original file is not changed.

Can I add a picture to an MP3 on my phone?

Yes, in a modern mobile browser. Everything runs on the phone, so very large files can run out of memory on older devices; start with a normal-sized song.

Should I use JPEG or PNG?

JPEG is the most compatible. PNG works in most modern players, but some older devices and car stereos only display JPEG covers.

Why is my MP3 album art not showing?

Usually the player is showing a cached image, the picture sits next to the file instead of inside it, or the device cannot read a large PNG. Open the new copy in a second player; if the cover shows there, refresh the first player's library or use a smaller JPEG.
