What Is a Facebook Text Overlay Checker
A Facebook text overlay checker is a pre-launch compliance tool for advertisers. Facebook limits how much text can appear in ad images because data shows that visually-driven creatives outperform text-heavy ones. The platform does not outright reject high-text images anymore, but it significantly reduces their delivery, which means fewer impressions and higher costs.
The checker works by applying a grid over your uploaded image and determining what percentage of grid cells contain text. It classifies results into tiers: low text (full delivery), medium text (reduced delivery), and high text (severely limited delivery). This mirrors the evaluation Facebook performs internally when processing your ad creative.
Knowing your classification before launching lets you redesign proactively. Move messaging from the image to the ad copy fields, reduce font sizes, or simplify overlays to bring text density down. The tool functions as quality assurance for your creative workflow. See also the Facebook image text checker for additional validation, and explore the AI text generator collection for writing tools.
How To Use the Facebook Text Overlay Checker
Upload the image you plan to use as ad creative. The tool accepts JPG and PNG formats. After processing, it returns a visual indicator of text coverage and a classification (low, medium, or high).
If the result shows medium or high text, revise your design. Effective strategies include moving headlines to the ad’s primary text or headline fields, using a smaller logo, eliminating decorative text that does not add information, or cropping the image to include more visual space.
Upload the revised version and verify it now falls in the low-text category. Repeat until compliance is confirmed. This iterative approach is faster than discovering delivery issues after your campaign is already consuming budget.
When To Use This Tool
Run every ad image through the checker as part of your creative approval process. This applies to all placements: feed ads, Stories, Reels covers, carousel cards, and video thumbnails. Each visual element Facebook displays as part of your ad undergoes its own text evaluation.
Design agencies delivering assets to clients should include overlay compliance as a standard quality check. In-house creative teams building asset libraries benefit from flagging non-compliant designs before they enter the scheduling queue. E-commerce brands running sale promotions with price overlays especially need to validate since numerical text counts toward the ratio.
Tips for Better Results
- Move all text you can to Facebook’s dedicated copy fields (headline, primary text, description)
- Use a wordmark-free logo version in ad images
- Allow at least 70% of the image to be free of any text or lettering
- Check each carousel card individually since Facebook evaluates them separately
- Combine with the FB ad text checker for a complete compliance workflow covering both visual and written elements

FAQ
How does the text overlay checker evaluate images?
It divides the image into grid sections and identifies which cells contain text. The percentage of text-occupied cells determines whether your image falls into low, medium, or high text categories, each with different delivery implications.
What happens if my image has too much text?
Facebook reduces ad delivery for high-text images. Your campaign may still run, but it reaches fewer people and costs more per result than a compliant creative with minimal text overlay would achieve.
Do logos count as text in the overlay check?
Yes. Text within logos, watermarks, and brand marks all count toward the overall text ratio. Consider using icon-only or wordmark-free logo versions specifically for ad images to keep text density low.
Can I check video thumbnails with this tool?
Yes. Export the thumbnail as a static image and upload it to the checker. Facebook evaluates video thumbnails using the same text overlay criteria it applies to static ad images for delivery decisions.
How do I create ad copy that complements low-text images?
