A clearer next step
for your PDF.

We inspect title and language metadata, tagging signals, tagged image descriptions, extractable text, bookmarks, numbered headings and tagged table headers across every page.

We cannot establish full conformance, detect every untagged image or table, judge alternative text, or verify visual contrast and logical reading order. Forms, links, font encoding and many other requirements are outside this first version.

Use the findings to improve the original document. For a full assessment, combine a dedicated validator with manual review and assistive technology testing.

The checker reads your selected file in browser memory. It does not upload the PDF, its name or its contents. Optional Google Analytics measures visits and whether a check or report download completes, only if you allow it. We do not send PDF names, contents, metadata or findings. Google receives browser and connection information and uses analytics cookies. There are no advertising scripts or user accounts.

The processing engine downloads when you choose a file or prepare offline use. Offline preparation works for this open tab, not for reopening the site without a connection. Closing the tab clears the working session. Reports are saved only when you download them.
