What each service asks of your master and cover

The one export that fits all eight

A 16-bit, 44.1 kHz stereo WAV, and a 3000 × 3000 RGB JPG under 10 MB. Keep your 24-bit master too: most services take it, and Spotify and TuneCore prefer it.

Everything below was read from each company’s own help or specification pages on 12 November 2026. Where a page does not state a value, it is left out here. Rules change, so each block links to its source.
