Feature

Edit any thumbnail just by asking

No layers, masks or design software. Drag a thumbnail into the chat, say what to change, and ThumbSpark creates a new version with only that part changed.

Edits that keep what already works

When you ask for a change, the current thumbnail is sent as the starting point, so only the part you mention changes. Your layout, character and colours stay put.

Every edit is saved as a new variation next to the original. Compare versions, keep the best one, and never worry about overwriting a design you liked.

Things you can ask for

  • “Make the text bigger and move it to the left.”
  • “Swap the background for a night-time city.”
  • “Change my expression to excited.”
  • “Add our logo small in the top-right corner.”
  • “Use the colours from this reference instead.”
  • “Make a version without any text for A/B testing.”

Tip: Making variations for an A/B test? Change one thing at a time — the text, the face or the background — so you know what made the difference. See how to A/B test thumbnails.

Bring your own images

Add logos, product shots or backgrounds to a reference library and mention them by name — “place @logo_white in the corner”. The image is sent to the model with your request.

Frequently asked questions

Does editing replace my original thumbnail?

No. Each edit creates a new version and the original stays in your project.

Does an edit cost the same as a new thumbnail?

Edits use credits like any generation, based on the model’s real cost. See pricing.

Can I edit a thumbnail I made somewhere else?

Yes — upload it to a project and ask for the change you want.
