Podcast cover art size and show details explained: the 1400 to 3000 pixel square rule, title, description, category, owner and feed address, checked before you submit.
Podcast cover art must be a square JPEG or PNG between 1400 and 3000 pixels on each side, in RGB colour. 3000 x 3000 is the size to aim for. StreamLive Pro checks the file when you upload it and refuses one that breaks these rules, so a cover that went in will not be the reason a podcast app rejects your show. The rest of the show details (title, description, category, language, owner) live in the same settings form.

| What the check says | What it means | Fix |
|---|---|---|
| Not square | Width and height differ | Crop to an exact square, for example 3000 x 3000 |
| Too small | Under 1400 pixels on a side | Export again at 3000 x 3000. Do not upscale a small logo; rebuild it at full size |
| Too large | Over 3000 pixels on a side | Export at 3000 x 3000 |
| Format | Not JPEG or PNG (for example WebP or HEIC) | Save as JPG or PNG |
| Colour space | CMYK or another non-RGB profile | Export as RGB (sRGB) |
| Suggestion: 3000 recommended | Valid, but smaller than 3000 | Optional: export at 3000 x 3000 |
| Suggestion: large file | Valid, over 1 MB | Optional: compress the JPG |
Design tips that hold for every app: a few large words that read at the size of a thumbnail, no tiny text, a solid background with no transparency, and nothing important in the corners.
| Problem | Fix |
|---|---|
| The app says the feed has no owner email | The owner email is written to the feed only after you verify it. See Verify your podcast owner email for the RSS feed |
| The feed check says there are no episodes | Apple requires at least one episode in the feed (Apple: podcast requirements). See Add an episode to your podcast RSS feed |
| The trial says your feed is private | A public feed needs a paid plan. You can keep building meanwhile |
| The end of the description is missing in an app | It passed 4,000 bytes. Shorten it, especially in Hebrew |
| You want a different feed address | It cannot change after creation. Create a new show before you submit, and delete the old one |
When the show is ready, submit the feed: Publish your podcast to Spotify and Apple Podcasts.

Yes. It is written in the feed so podcast apps can send you the ownership code. It goes into the feed only after you verify it.
Yes. You can set up the show, the cover and episodes on the trial. The feed becomes readable by podcast apps on a paid plan.
