When you have only a flattened video thumbnail without editable layers, ReWords AI modifies baked-in words on your PNG or JPG cover.
Select existing text, submit your replacement phrase, and download an updated graphic with best-effort font matching without rebuilding artwork.
HOW IT WORKS
Update text baked into finished video covers in four simple steps without rebuilding layouts.
Upload your finished video cover PNG, JPG, or WebP file without needing original design projects.
Select the baked-in text block you need to modify or leave blank to remove unwanted copy completely.
Enter your new wording while our system performs a best-effort style match against surrounding lettering.
Review the generated revision and download your updated thumbnail ready for immediate upload.
THE TOOL
When video covers are exported, typography becomes permanently flattened into the image pixels. Thumbnail text editor helps because, if you do not have access to the original design project, changing a title or episode number previously required remaking the entire artwork from scratch.
Operating inside the Replace tab, the tool lets you directly replace text in image assets with best-effort style matching so fresh episode numbers and titles blend into existing graphics. Similar workflows are available across our broader edit text in image hub, the all-around ai image text editor, a dedicated banner text editor, and our companion book cover text editor. If you simply need to clear unwanted scribbles, you can remove writing from photo backgrounds using trial credits after sign-in, with costs scaling at 10 credits for 1K, 20 for 2K, and 30 for 4K.
COMMON USE CASES
Common situations where video creators and content teams edit flattened thumbnails instead of rebuilding templates.
Update episode numbering or title text on archived video covers when source project files are lost or inaccessible.
Adjust callout wording across video thumbnails adapted for course platforms, streaming portals, and internal libraries.
Correct misspellings, update guest names, or adjust release dates directly on finalized cover graphics.
WHY IT MATTERS
Layered graphic tools are great when master files exist, but video editors and creators often work with finalized export files across platforms. If you need YouTube-specific thumbnail adjustments, visit our dedicated [YouTube thumbnail text editor](/edit-youtube-thumbnail-text).

APPROACH COMPARISON
Understand the tradeoffs between in-place replacement, overlay patches, and starting from scratch.
Replaces baked-in letters on the flattened cover image with best-effort font matching, preserving existing backgrounds in one upload step.
Placing a solid color box over old thumbnail text and typing new copy creates visible seams and obscures background artwork.
Thumbnail text editor eliminates the need to track down missing project files, subject photos, and custom fonts to recreate lost layouts, which requires multiple assets and extensive manual effort.
