Podcast Artwork Image Required
The requirements for your podcast artwork image are designated by Apple Podcasts’ guidelines. This is why we refer to it as the Apple Podcasts Artwork within PowerPress beginning in version 8.3.
The image dimensions must be at least 1400 x 1400 pixels in .JPG or .PNG format and must not exceed 3000 x 3000 pixels. It must use RGB color space and the file size must be 0.5MB (500kb) or less.
A square 1400 x 1400 pixel image in .JPG format is recommended. This image is the standard for the majority of podcast directories. It is not the artwork that is displayed during episode playback, which is why we’ve added additional options within PowerPress to enable that functionality.
Note: If you change the artwork image without changing the file name, it might take some time (days or even months) for directories to update the image in each directory you’ve submitted your RSS feed. Keep in mind it may take up to 24 hours for your image to update after making a change.
It is possible to use episode-specific images, but please keep in mind that not all podcast apps and platforms use them, so your mileage may vary.
The same specifications for the main artwork image apply to episode-level images. Beginning with PowerPress 8.2 we included settings within the Podcast Episode box to add these easily. It may also be helpful to add the images in your ID3 tags if you’re using MP3 media files, as some podcast apps will utilize the tags in order to display episode-level images.
