Complete guide

Choose text replacement when the thumbnail is flattened

If you still have the editable Canva, Photoshop or Figma source, changing its original text layer gives maximum control. This page is for a finished thumbnail where the words are pixels and the source design is unavailable.

What is this thumbnail text editor?

It is an AI workflow for removing and replacing visible words already flattened into a thumbnail image.

Who uses it?

Video creators, social teams, podcasters and marketers use it to correct or refresh authorized campaign and channel graphics.

What task does it solve?

It changes an existing hook, number, year or short label while aiming to keep the subject, background and visual hierarchy intact.

How is it different from adding overlay text?

An overlay places another layer above the old headline. Replacement targets the original text region and reconstructs the pixels beneath it.

What should you do next?

Upload a clear original, replace one concise headline, and review the complete image at full size.
