Making your cover

Where do I start?
Pick a template, or type your show's name in Titles. You can also double-click the title on the cover to type there (on a phone, tap it, then tap again).
How big is the download?
The cover is 3000 × 3000 pixels, the largest Apple Podcasts accepts. Other sizes download at the size each platform asks for.
Is my design saved?
Yes, in this browser as you work, up to 10 designs. Nothing is sent to Castos. Clearing browser data, a private window or another device starts fresh, so to keep a design for good, download it as a file from Designs.
Can I make art for each episode?
Yes. In Episode, add an episode number, title, guest name or photo. For each new episode, fill them in and download. The file name includes the number.
Can I move several things at once?
Yes. Shift-click (or Cmd/Ctrl-click) each one, or drag a box around them on an empty part of the design. Cmd/Ctrl+A picks everything. Then drag, nudge with the arrow keys, duplicate or delete them together. Align lines them up with each other or spaces them evenly; with one item, it lines that item up on the cover.

Your designs

Saved in this browser, up to 10. A new one past that replaces the oldest. Download a design as a file to keep it or open it on another computer.
