Overview of feed requirements

Apple Podcasts has very specific feed requirements. Below we will list out the basic requirements and their corresponding fields in Publish.


Podcast feeds must conform to RSS 2.0 specifications.

If you’re hosting the feed on your own servers please ensure that there are NO duplicate <enclosure> URLs in your feed. Apple podcasts will ignore previously used <enclousre> URLs.

Apple Podcasts recommends artwork for a podcast be in the JPEG or PNG file formats and in the RGB color space with a minimum size of 1400 x 1400 pixels and a maximum size of 3000 x 3000 pixels at 72 DPI. The size should be 512kb (while Apple Podcasts does not recommend an image size, this meets the requirements for NPR One and Spotify).

All podcast episodes, XML, and artwork are hosted on publicly addressable servers with byte-range requests enabled.

All podcasts must contain a GUID (globally unique identifier).


You’ll need to have very specific tags in your RSS feed in order to submit it to the podcast apps out there. Below is the list that was promised. We’ve broken down the required tags and the corresponding fields in Publish.
