You can add MP3 files to Spotify on Windows using the Local Files feature, which lets you play music stored on your computer alongside your Spotify library

Spotify's Local Files feature works by pointing to folders on your PC where you keep MP3s. Once you set it up, those songs appear in a separate section of your library and play in the same queue as your regular Spotify tracks. The process takes about five minutes and requires no additional software.

The main limitation is that Local Files only work on the device where they're stored — you cannot sync them to your phone or tablet, and they won't play on other computers logged into your account. If you want to hear your MP3s on multiple devices, you'll need to use a different method, like uploading them to a cloud service or converting them to a format Spotify recognizes natively.

Key Takeaways

  • Local Files must be enabled in Spotify settings before your MP3s will show up in your library.
  • You point Spotify to a folder on your PC, and it scans for MP3, M4A, WAV, and OGG files in that location.
  • Local Files play only on the computer where they're stored, not on your phone or other devices.
  • Song metadata (title, artist, album) must be correctly tagged in your MP3 files, or Spotify may not recognize them properly.
  • If Spotify doesn't find your files, check that the folder path is correct and the files aren't corrupted.

Enable Local Files in Spotify Settings

Open Spotify on your PC and log in. Click the three horizontal lines (menu icon) in the top left corner, then select Settings. Scroll down until you see the Local Files section — it appears near the bottom of the settings page.

Toggle the switch next to Local Files to turn it on. You'll see a message saying "Show Local Files" is now enabled. After you enable it, a new section called Local Files will appear in your library sidebar on the left side of the Spotify window. This is where your MP3s will show up once Spotify finds them.

Tell Spotify Where Your MP3 Files Are Stored

While still in Settings, look for the Local Files section and find the option to add a folder. Click the plus icon or Add a Source button. A file browser window will open.

Navigate to the folder on your PC where you keep your MP3 files. You can choose any folder — your Music folder, a custom folder, or even a folder on an external drive. Select the folder and click Open or Select Folder. Spotify will now scan that folder for music files. The scan usually takes a few seconds to a minute, depending on how many files you have.

You can add multiple folders if your MP3s are scattered across different locations. Just repeat the process for each folder. Spotify will search inside subfolders too, so you don't need to move all your files into one place.

Check That Your MP3 Files Are Tagged Correctly

Spotify relies on metadata — the hidden information inside an MP3 file that tells it the song title, artist name, and album — to organize your music. If a file has missing or incorrect tags, Spotify may not recognize it or may file it under "Unknown Artist" or "Unknown Album."

Before adding files to Spotify, open a few of your MP3s in a media player or tagging tool and check that the title, artist, and album fields are filled in. On Windows, you can right-click an MP3 file, select Properties, and click the Details tab to see and edit basic information. For more detailed editing, use a free tool like MusicBrainz Picard or MediaInfo.

Files with no tags at all will still appear in Local Files, but they'll be harder to find and won't sort neatly into your library. Spending a few minutes tagging your files makes them much easier to use.

What File Formats Spotify Accepts

Spotify's Local Files feature works with MP3, M4A (iTunes audio), WAV, and OGG files. If you have music in other formats — like FLAC, WMA, or AAC — you'll need to convert them first. Free conversion tools like Audacity or VLC Media Player can handle most formats.

MP3 is the most common format and works without any extra steps. If you're converting files, MP3 is usually the safest choice because it's widely supported and keeps file sizes reasonable.

Troubleshoot If Your Files Don't Appear

If you've enabled Local Files and added a folder but your MP3s still don't show up, start by checking the folder path. Go back to Settings, look at the Local Files section, and confirm the folder you added is listed there. If it's not, add it again.

Next, verify that the files themselves are valid MP3s. Corrupted files or files with the wrong extension (for example, a file named "song.mp3" that's actually a different format) won't play. Try opening one of the files in a media player like Windows Media Player or VLC to confirm it works.

If the files play in another player but not in Spotify, restart Spotify completely — close it and open it again. Sometimes Spotify needs a restart to finish scanning a folder. If that doesn't work, remove the folder from Local Files settings and add it again to force a fresh scan.

Finally, check that Local Files is still enabled. Spotify sometimes disables it after updates, so go back to Settings and confirm the toggle is switched on.

Understand the Limits of Local Files

Local Files are tied to the specific computer they're on. If you log into your Spotify account on a different PC, those files won't appear — only the files stored on that new computer will show up. This is a security feature to prevent unauthorized copying of music files.

You also cannot sync Local Files to your phone or tablet using Spotify's mobile app. If you want to listen to your MP3s on the go, you'll need to use a different app or service. Some people use cloud storage like Google Drive or OneDrive to store MP3s and play them through a separate app, but that's outside Spotify.

Local Files do appear in your Spotify playlists if you add them, and they'll play in the correct order when you play the playlist on your PC. However, if you share a playlist that includes Local Files with someone else, they won't be able to hear those tracks — only the regular Spotify songs will play for them.

Frequently Asked Questions

Can I listen to my Local Files on my phone?

No. Local Files only work on the computer where they're stored. Spotify's mobile app does not support Local Files. If you want to hear your MP3s on your phone, you'll need to use a different music app or upload the files to a cloud service.

What happens if I delete the MP3 files from my computer?

They'll disappear from Spotify. Local Files are just shortcuts to files on your PC — Spotify doesn't copy them into its own storage. If you delete the original files, Spotify will no longer find them, and they'll vanish from your library and playlists.

Can I add Local Files to a shared playlist?

You can add them to a playlist on your PC, but other people won't hear them. When someone else plays the playlist, the Local Files will skip, and only the regular Spotify tracks will play. This is why Local Files are best for personal playlists.

Do I need to keep the folder in the same location?

Yes. If you move the folder or rename it, Spotify won't find the files anymore. If you need to reorganize your files, remove the old folder from Local Files settings and add the new location.

Why does Spotify show "Unknown Artist" for some of my files?

The MP3 file's metadata is missing or incomplete. Right-click the file, select Properties, click Details, and fill in the Title, Artist, and Album fields. Save the changes and restart Spotify to see the updated information.
