AI Thumbnail Editor for Video Courses

How it works

1. 1

   Upload the instructor or course photo

   Drop the instructor headshot, lesson screenshot, or course image into EditThisPic. Works with photos taken at home, at events, or screenshots from recording sessions. Best results when the subject is clearly visible.

   Expect: Course thumbnail edits process in 15-25 seconds. Background replacements may take up to 30 seconds.
2. 2

   Describe what needs changing

   Type the edit: 'replace the home office background with a clean gradient background in dark navy', 'remove the bookshelf behind me and fill with a solid dark background', 'brighten the photo and even out the lighting'. Be clear about what the replacement should look like. No selection tools needed.

   Tip: Course thumbnails need to work at small sizes in course directories. Dark backgrounds with good contrast between your face and the background make thumbnails readable at any size.

   Preview at thumbnail size

   Course thumbnails appear small in Udemy search results and marketplace listings. Check that your face is clearly visible and the background isn't competing for attention. Clean, high-contrast works best.
