Add album art to MP3 — in your browser

How to add album art to MP3 files — step by step

1. Open the MP3. Drop it onto the tool above or click to browse. Its current tags and cover (if any) load instantly.
2. Choose the artwork. A square JPG or PNG — 600×600 to 3000×3000 pixels is the useful range. No cover on hand? Pull the official one with our Album Art Finder first.
3. Download the result. Press “Download MP3 with cover” and a copy with the art embedded lands in your downloads — original untouched, every tag preserved.

That's the whole job: to add album art to MP3 files you don't need iTunes, an installer, or an account — a browser tab does it in under a minute.

Embedded artwork vs cover.jpg — why embedding wins

There are two ways artwork travels with music: a cover.jpg sitting in the album folder, or an image embedded inside each file's tag (the ID3 APIC frame). Folder images are fragile — move a file, send it to a friend, load it on a phone, and the art stays behind. Embedded art is part of the file itself: it survives copying, syncing, streaming from a NAS, and every player from CarPlay to a €30 MP3 stick shows it. When a player displays a gray square for one album, a missing embedded cover is the usual culprit — and embedding it is exactly what this tool does.

What size and format should the artwork be?

Square, always. Players assume album art is 1:1; anything else gets cropped or letterboxed, usually badly. 600×600 to 3000×3000 pixels is the useful range — 600px covers phone screens, 1200px is the sweet spot for desktop players and CarPlay, 3000px is archival grade for a library you'll keep forever. JPEG vs PNG: JPEG is the right default for photographic covers (smaller files, invisible difference); PNG earns its bytes only on flat graphic art with hard edges. And watch the file size — embedding a 15 MB scan into every track bloats the files and makes some hardware players stutter when browsing; under 1–2 MB per cover keeps everything happy. If the cover you found is tiny or blurry, don't upscale it — grab the official high-resolution version with our Album Art Finder instead.

Troubleshooting: the cover still doesn't show

You embedded the art, and a player still shows a gray square. Three usual suspects, in order: caching — most players thumbnail artwork on first import, so remove the track and re-add it (or clear the artwork cache) to force a refresh; the wrong copy playing — remember this tool downloads a new file with “(cover)” in the name, and it's easy to keep playing the original; and sync pipelines — some services re-compress or strip embedded images on upload, in which case the fix belongs on that service's side, not in the file. If all three check out, open the file in our ID3 Tag Editor and confirm the cover is really in the tag — thirty seconds of certainty beats an evening of guessing.

When a desktop tagger is the better tool

This page is built for the common case: a handful of files that need proper covers, fixed from any computer with zero setup. If you're retagging an entire library — hundreds of albums, automatic cover lookups, filename rules — a desktop tagger like Mp3tag or MusicBrainz Picard is the honest recommendation: batch operations are their home turf. The trade-off is the usual one — installation, a learning curve, and your files have to live where the software does.

Clean tags make the artwork worth it

A perfect cover on a mislabeled file is half a fix. While you're at it, check the text side of the tag — title, artist, album artist (the one that keeps compilations together) — with our ID3 Tag Editor, which edits everything this tool preserves. And if you ever need to go the other way and pull artwork out of files, that's what Extract Album Art does. Together the three cover the whole loop: find, embed, extract.
