How MP3 Album Art Works

A cover for MP3 files is not a separate image sitting next to the song. It lives inside the file, in the ID3 tag at the start of the MP3, as a picture frame that holds the image itself, its type (JPG or PNG) and a label saying what it is: front cover, back cover, artist photo and so on. Players look for the front cover and show it on the lock screen, the car display and the desktop app. A folder.jpg next to your files only works in some apps and gets lost when you copy one song somewhere else. When you add album art to MP3 files, the art travels with each file, wherever it goes.

Why Add Album Art to MP3 Files Here

A cover tool that does the fiddly parts for you, without an install or an upload.

  • Nothing leaves your device

    The songs and the picture are read and written inside your browser tab. Unreleased tracks stay private.

  • Square, every time

    Players expect a square cover. Drag the crop box over any photo, or keep the whole image on a black, white or blurred fill.

  • The right size

    Resize to 1000, 1400 or 3000 pixels, so a 12 megapixel phone photo does not add megabytes to every track. Already sized? Embed the JPG or PNG as it is.

  • One cover, whole album

    Select every track and apply the picture to all of them at once, instead of one file at a time.

  • Audio left alone

    Only the tag changes. The audio frames are copied byte for byte, so the song sounds exactly as before.

  • Any computer, no install

    Works in a current browser on Windows, macOS, Linux and ChromeOS, free and with no account. FLAC and M4A files take covers too.

How to Add Album Art to MP3 Files

Here is how to add album art to an MP3, or to a whole album, in three steps.

  1. Drag one song or a whole album onto the editor at the top of this page. Each file shows its current cover, or an empty square if it has none.

  2. Choose a JPG, PNG or WebP, drag the crop box to frame it square and pick 1000, 1400 or 3000 pixels. Apply it to one file or to every selected file.

  3. Download one MP3 or every edited file in a ZIP. The cover is now embedded, the audio inside is unchanged, and your original files stay as they were.

A Cover for MP3 Files, Done Properly

An MP3 cover adder that also checks the picture, so it shows up everywhere you play the song.

Crop square and size it right

Drop in any picture: a photo, a poster, a screenshot. Drag the crop box to choose the square, then pick a size. 1000 pixels is plenty for phones and car displays, 1400 matches what podcast apps ask for, and 3000 is the size distributors want for a release. If the crop is smaller than the size you pick, the editor warns you that it will look soft. Need artwork first? Design it in the album cover maker.

Crop a Cover

Add album art to MP3 albums in one go

Select all twelve tracks, add the picture once and apply it to every file. Each MP3 gets its own copy of the cover, so a single song copied to a phone or a USB stick still shows the art. While the album is open, fix the album name and track numbers in the MP3 tag editor.

Cover an Album

See, save or remove the current cover

Each file shows the art it already has. Save it as an image file, replace it, or delete it, so the editor works as an MP3 cover editor and an album art remover in one. Handy when a download came with the wrong art or a huge picture.

Check My Covers

Check that it worked

Drop the saved file back on the editor and the cover is there. On Windows, File Explorer shows it as the file icon in Large icons view; on a Mac, select the file and press Space for Quick Look. VLC and the Music app show it while the song plays.

Real MP3 Cover Art, Inside the Tag

After you add album art to MP3 files, this is how the cover is stored: cropped, sized and labeled as the front cover.

What you are looking at

Add a picture to MP3 files here and this is what gets written. The picture frame of a saved MP3: front cover, JPG, 1400×1400 pixels, inside an ID3v2.3 tag in front of the audio. The same frame is copied into every track you apply it to. Want this cover on screen, not just in the file? Turn the MP3 and its art into a video with MP3 to MP4.

What Size Should MP3 Album Art Be?

Before you add album art to MP3 files, size it. The short answer: a square JPG between 1000 and 3000 pixels.

Square, always

Players draw the cover in a square. A wide picture gets squeezed or cut, so crop it yourself and choose what stays.

1000 to 3000 pixels

1000×1000 is sharp on any phone. 3000×3000 is what stores and distributors ask for. The album cover size guide lists every platform.

JPG for photos

JPG keeps photos small. PNG suits flat artwork with text, but the file is larger. Both are standard in ID3 tags.

Keep it light

Every track carries its own copy. A 3 MB picture on a 12 track album adds 36 MB; at 1000 pixels the same cover is a few hundred KB.

Who Needs a Cover for MP3 Files

Anyone whose songs play from a file rather than a streaming app needs a cover for MP3 files.

Artists sending promos

A promo MP3 with the cover inside looks finished in a curator’s player, not like an anonymous file.

DJs

Album art makes a crate easier to scan. Put a cover on MP3 files bought or recorded without one.

Podcasters

Embed the show art in each episode file, at 1400 pixels, for listeners who download and play the MP3 directly.

Collectors of old rips

CD rips from years ago often have no art. Find album covers for MP3 folders, then check each MP3's cover, album title and track numbers, album by album.

Car and phone listeners

A USB stick in the car or files on a phone look far better with a cover on each song.

Audiobooks and courses

Give every chapter the book cover, so the player shows which title you are listening to.

Add Album Art to MP3: FAQ

Sizes, formats, checks and the cases where the cover does not show.

How do I add album art to an MP3?

Drop the MP3 on the editor at the top of this page, add a JPG, PNG or WebP, crop it square, pick a size and download the file. The cover is written into the file as the front cover. That is how to add album art to an MP3 on any computer, with nothing to install.

How to add an album cover to an MP3 without software?

Use a browser tool like this one: it needs no install on Windows, Mac, Linux or a Chromebook. Built-in options are thin. Windows File Explorer cannot add a cover, and the Music app on a Mac only does it for songs in its library (Get Info, then Artwork).

What size should album art for an MP3 be?

A square image of 1000×1000 to 3000×3000 pixels. 1000 to 1400 is enough for phones, cars and players and keeps each file small; 3000 matches what distributors ask for. See the album cover size guide for platform sizes.

Should the cover be JPG or PNG?

JPG for photos and most artwork, since it is much smaller. PNG for flat graphics with sharp text. Both work in ID3 tags, and every common player reads them.

How do I check that the cover was added?

Drop the saved file back on the editor: the cover shows in its row. On Windows, switch File Explorer to Large icons and the cover becomes the file icon. On a Mac, select the file and press Space. VLC, the Music app and phone players show it while the song plays.

Can I add one cover to many MP3 files at once?

Yes. Select the files, add the picture once and apply it to all of them, then save them as a ZIP. Each file gets its own copy, so the art stays even when one song is copied on its own.

Why does my car stereo not show the cover?

Some car stereos show no album art at all, and some skip covers that are very large. Try a square JPG at 1000 pixels or less, saved by EzVisualizer as the front cover in an ID3v2.3 tag, the version most head units read. If it still does not show, the stereo probably does not support covers.

Can I add cover art to WAV files?

Not here: this tool can add album art (MP3, FLAC and M4A files) but does not write WAV. A WAV can carry a picture in an extra tag chunk, but many players ignore it. Desktop taggers such as Mp3tag or Kid3 can add cover art to WAV files; for a release, distributors take the cover as a separate upload anyway.

Does adding a cover change the sound?

No. The cover goes into the tag and the audio frames are copied byte for byte. The file grows by the size of the picture, nothing else changes.

Can I save the cover that is already in an MP3?

Yes. Drop the file, open the Cover tab and download its current art as an image. Useful when you want the same cover for a playlist, another file or a video made with the audio visualizer.

How do I remove album art from an MP3?

Select the file, remove the cover and download it. It works as an album art remover for one file or a whole selection, and leaves the other tags and the audio as they were.

Where can I get album covers for MP3 files?

For your own music, design one in the album cover maker. For albums you own, search MusicBrainz from the editor to confirm the release, then add the cover from your CD booklet scan or a picture you have the rights to, the right album cover for MP3 copies of it. Only the artist and title you type are sent.

Is this an MP3 image adder for phones too?

Yes. It opens in the browser on iPhone and Android, so you can add an image to MP3 files on the go. Selecting many files is easier on a computer.

Is it free, and are my files uploaded?

It is free with no sign-up, and nothing is uploaded: the files are read and saved inside your browser tab. Add album art to MP3 files as often as you like, up to 1,000 at a time.
