Frequently asked questions
How do I check if a PDF is accessible?
Upload the PDF and click Check Accessibility. The tool checks the document title, language, tagged structure, bookmarks outline, and whether pages contain readable text, then gives a score.
Is my PDF uploaded to a server?
No. Checking happens entirely in your browser with an open-source PDF library — your file never leaves your device.
What makes a PDF accessible?
A document title, a set language, a tagged structure for screen readers, bookmarks for navigation, and real text (not just scanned images) on every page.
My PDF is a scan with no text — what should I do?
Run it through OCR first (our free image-to-text approach can help for single pages) or re-export it from the original document so it contains real text.
Does a high score here mean full WCAG compliance?
Not fully. This checks the document-level signals that matter most. Complete validation — reading order, image alt text, table headers — still needs a desktop checker like Adobe Acrobat Pro.
Can I check many PDFs at once?
One file at a time for now — check each PDF and keep the downloaded text report with your publishing records.
