A title is missing

No document title found.

A filename is not the document title. A useful title helps readers identify the document in a PDF viewer.

What to do next

Add a descriptive title in the source document or PDF editor, then export and check again.

For people who publish PDFs

From a folder of files to a review plan.

For website editors, designers and teams sharing documents. Check one PDF or compare a batch.

    See which files need attention and what to check next.

  3. Take the notes with you

    Save the results in a spreadsheet, or print a report to share.

A useful first check

Know what this can tell you.

It reads titles, language settings, tags and text. A missing setting can point to work; a setting that exists can still be wrong.

Continue with a human review

Reading order, correct tags, image descriptions, links, forms, contrast and text recognition accuracy are not checked. This is not a full audit or WCAG / PDF/UA certification.

Use a dedicated validator such as PAC alongside inspection with assistive technology.

File limits and privacy

20 PDFs per batch, 20 MiB each, 100 MiB total, 200 pages and 60 seconds per file. Password-protected PDFs and unsupported forms need a different tool.

PDFs are processed in browser memory without document storage or remote AI. Reports contain filenames and metadata: review them before sharing. The browser loads parser assets from this site; full offline use is not provided.

Start with the PDFs you have.

No setup. Choose your files and get review notes.
