Our online validation tool creates a validation report that determines which parts of your PDF do not comply. We use an open-source validator veraPDF, and validation produces a report by the PDF/UA validation rules.

Additionally, you can download our desktop version, PDFix Desktop Lite, a free PDF viewer, and PDF Accessibility Checker to effortlessly validate your PDF documents.
