About Diana Kosovac, PDFix


Font embedding issues remain a leading cause of PDF/UA validation failures, preventing screen readers from reliably interpreting text and blocking accessibility compliance.

PDFix now integrates callas software's font correction technology through its Action Marketplace, enabling automated detection and repair of font issues in minutes. The process is straightforward. After a one-time Docker setup, users can run the Fix Fonts action directly within PDFix Desktop.

Results include passing PDF/UA font validation checks, improved screen reader text interpretation, and consistent rendering across platforms.

For developers and enterprise teams, the PDFix SDK enables integration of font fixing into automated workflows and batch processing pipelines. Desktop users can access the font fixing capability at no additional cost.
