Snappa

Snappa is a straightforward graphic design tool aimed at marketers and creators who need thumbnails, social posts, and banners without learning a full design program. It has preset sizes for every major platform baked in.

It fits podcasters who want a consistent thumbnail template they can reuse each episode, just swapping the episode title and guest photo, without opening something as heavyweight as Photoshop.

The free tier's download cap becomes a real limit once you're publishing weekly and need a new thumbnail, cover art variant, or quote graphic every time.

It won't replace a dedicated designer for a show with a strong visual brand, but for consistent, decent-looking basics on a budget, it does the job.
