About This Tool

Purpose and scope: The tool analyzes Facebook image text overlay to determine compliance with traditional text-density expectations for ads and posts. It targets social media teams, creative agencies, and ad operations professionals who preflight assets before submission. By evaluating visible text regions relative to the image area, it yields a quantitative overlay percentage and a compliance verdict, enabling early design decisions and faster approvals. It does not require manual counting or guesswork.
How it works conceptually: The tool identifies text regions using image analysis heuristics, computes the portion of the image occupied by text, and expresses this as an overlay_text_percentage. A threshold (default 20%) governs the compliance verdict, with the option to adjust for regional rules or varying ad formats. Results include a verdict, percentage, and a confidence score for robustness.
Core features and use cases: Upload an image and receive an objective text-density assessment, a recommended action (e.g., reduce text to X%, replace text with a logo, or crop), and an exportable report. Useful for preflight by marketing teams, design studios, and ad ops to minimize revision rounds and approval delays.
Value and differentiation: This tool focuses on Facebook visual policy expectations and provides concrete, actionable guidance rather than generic text analysis. It supports rapid iteration, multi-language considerations, and regional guideline alignment while clearly communicating uncertainties and edge cases.

Frequently Asked Questions

Find Quick Answers

What is the 20% text rule?
Historically, Facebook preferred images with 20% or less text to optimize reach and readability. The tool uses this as a practical benchmark, but actual policy varies by region and ad type, so consider adjusting the threshold for specific campaigns.
What input formats are supported?
The tool accepts JPEG and PNG images up to 10 MB. Vector formats are not supported in file upload mode. For batch checks, prepare individual files and run sequential analyses.
What outputs are provided?
Outputs include a compliance boolean, overlay_text_percentage, a confidence score, and a recommended_action. An optional detailed_report can summarize detection details and suggested edits for designers.
Does the analysis consider logos or multiple text blocks?
Yes. The analysis aggregates legible text regions across the image. In complex overlays, the result may over- or under-estimate; use the recommendations to refine typography, sizing, or cropping.
