Stores are strict about files. Meeting these upfront avoids rejections and delays.
Audio master
- Upload a lossless file: WAV, FLAC or AIFF.
- Use the best-quality master you have. No MP3s or other lossy files.
- After upload the file is stored, then processed. You will see Ready when it passes, or Rejected if something is wrong (upload a new master in that case).
Cover artwork
- Must be a perfect square.
- Minimum 1500 x 1500 px. We recommend 3000 x 3000 px for best quality.
- JPG, PNG or WEBP, up to 30 MB.
- No blurry images, and no store logos (Spotify, Apple, and so on) on the cover.
If your image is not square or too small, the uploader tells you the exact size it detected so you can fix it.
