PDF score calculation
How is the PDF score calculated?
The PDF score in Eye-Able Report is a quality indicator that rates a PDF file based on the accessibility issues detected. It shows you at a glance how well your document meets the current PDF/UA and WCAG guidelines.
Starting point of the PDF score
Every PDF file starts with a score of 100%. This corresponds to a document with no detected issues.
How the score is reduced
For each issue detected in the PDF, the score is reduced by a certain number of points.
How many points are deducted depends on the severity (weighting) of the issue. Issues are categorised according to their level of impact. This determines how strongly a single issue affects the score:
- Critical error (highest impact): 60 points
- Error: 10–30 points
- Warning: 2 points
- Hint (lowest impact): 1 point
Issues with higher severity result in a greater reduction in the overall rating.

What a score of 0% means
A score of 0% means that so many points have been deducted that the PDF’s score is 0%.
Why the score can remain at 0% after improvements
If you improve your PDF and the score still shows 0%, there are still many issues present.
You have made improvements, but not enough issues have been fixed yet to bring the score above 0%.
This does not mean that your PDF has not improved. It simply shows that further corrections are needed before the score increases.
