How to edit only one part of a YouTube thumbnail with AI?
Open Inpaint Editor, paint the exact region to change, and describe the replacement. Only masked pixels are regenerated while the rest of the image stays intact.
Loading...
Do not regenerate the entire thumbnail when only one area needs work. Select a region, describe the change, and repaint just that section while the rest stays intact.

AI generated a weird face? Select it and regenerate with a better expression. No need to redo the whole thumbnail.
Distracting element in the background? Select it and describe what should replace it — or just remove it entirely.
Keep the subject but swap the entire background. Go from studio to outdoor, from office to space, from city to nature.
Select an empty area and add text overlays, icons, arrows, or other visual elements with a simple text prompt.
Select a region and adjust its color temperature, brightness, or mood without affecting the rest of the image.
Original thumbnail is always preserved. Experiment freely — inpaint as many times as you want on different areas.
Use the brush tool to paint over the region you want to change. Adjustable brush size for precision.
Type what you want in the selected area. For example: 'a surprised facial expression' or 'a sunset background with orange sky'.
Only the selected region is regenerated. The rest of your thumbnail stays exactly as it was. Takes about 10-20 seconds.
Open Inpaint Editor, paint the exact region to change, and describe the replacement. Only masked pixels are regenerated while the rest of the image stays intact.
Mask just the face area, then prompt for expression and realism constraints. Keep the mask tight to avoid scene drift and preserve composition.
Use specific prompts that preserve lighting, skin texture, and style. Small targeted masks plus one focused change produce cleaner blends than broad edits.
Each inpaint result is saved as a new revision linked to its source image. Timeline and before-after previews help you compare Original, Edit 1, Edit 2, and beyond.
Try It In Studio
We will highlight the canvas flow first. If you already have a thumbnail, open Edit from there. If not, generate one first and then jump into inpaint.
If you are not signed in yet, we will route you through sign-in first and then bring you straight back into the relevant studio workflow.
Read the feature page first so the workflow makes sense before you enter Studio.
You sign in first, then return to the exact same feature flow.
