Spotify boasts a catalog of over 100 million tracks, yet every music lover eventually runs into a wall: rare mixtape tracks, live bootlegs, unreleased local band demos, or old ripped CDs that simply aren’t on streaming services. Fortunately, Spotify includes a Local Files feature that lets you import offline audio files into your library and play them side-by-side with official streaming releases.
Supported File Formats
Before importing your library, check that your audio files match Spotify’s supported codecs:
| Format | Native Support | Notes |
|—|—|—|
| MP3 (.mp3) | Fully Supported | Ideal for most local audio files. |
| M4P / MP4 (.m4p, .mp4) | Fully Supported | Audio-only tracks; video MP4 files are not supported. |
| FLAC / WAV | Partial / Requires Codecs | Desktop clients often require specific system codecs; converting to standard MP3 guarantees compatibility. |
| M4A / iTunes Lossless | Not Supported | Apple Lossless or protected formats must be converted to MP3 before importing. |
