What does this tool do?

ADATool automatically fixes common accessibility issues in PowerPoint (.pptx), Word (.docx), and PDF files: missing alt text, missing titles, low-contrast text, incorrect reading order, missing table headers, document metadata, and more.

How long does it take?

Remediation takes about 1-2 seconds per image for alt text generation, plus a few seconds for structural fixes. A typical file finishes in under a minute. Multiple files are processed in parallel.

File retention

Completed files are available for download for 1 hour, then automatically deleted. Download your results promptly. Failed files are retained briefly for debugging, then purged.
