Batch Add Album Cover to MP3 Files

Complete the task in three clear steps

1. 1

   Choose up to 20 MP3 files

   Select or drag a group of tracks. Every file is validated before processing begins.

2. 2

   Choose one shared cover

   Upload JPG, PNG, or WebP artwork. It is prepared once as a compact JPEG and reused across the batch.

3. 3

   Process and download

   The editor handles one MP3 at a time, verifies each new tag, and reports individual failures without discarding successful results.

What the browser changes—and what it leaves alone

Batch processing is useful when every track belongs to the same album, release, event, or podcast series. The same image is embedded in every selected MP3, while each file keeps its own title, artist, album, lyrics, and audio stream.

Large batches create large downloadable Blob objects in the browser. For that reason the tool limits a run to 20 files, recommends desktop use for files over 150 MB, and provides individual downloads instead of duplicating every audio file again inside a ZIP archive.

When this tool is a practical fit

• One album split across several MP3 tracks
• Podcast episodes sharing series artwork
• Small curated folders that need a consistent image

Supported behavior and honest limits

• Up to 20 files in one run
• Sequential processing limits peak memory
• Every result is verified independently; a single unsupported tag does not cancel the entire batch
