        Ordering adds what this free check can't: our AI agents add the tags a screen reader follows (headings, reading order, lists, tables with their header cells, a text description for each image, a document title and its language). Your check report shows every page of your original and of the tagged file side by side with the number of pixels that differ, the result of veraPDF on the PDF/UA-1 rules that software can test, and each image next to the description we attached to it.

        • The tagged PDF and its check report, by email within one business day of payment.
        • Every page looks exactly as it does now. We add the structure; we don't change the wording or the layout.
        • You pay by card on a checkout page hosted by Stripe, before we start. The checkout price is the total you pay.

        If we don't email the tagged file and its report within one business day of your payment, or we find we can't tag the file, we refund you in full without your asking. If you find a problem in the file's structure within 30 days of delivery, tell us and we fix it free; if we can't, we refund that file in full.

        We can't tag this file

        Why

        The report is still yours. The full list of files we don't take is in our Terms.

        What the checker looks at

        Each line of the report is one plain sentence, with the page numbers where they apply.

        • The number of pages.
        • Whether the file is tagged: the hidden structure a screen reader follows.
        • The document title.
        • The language set for the text.
        • Images with no text description.
        • Tables, and whether they have header cells.
        • Scanned pages.
        • Form fields.
        • Signs that the reading order needs a look: columns, and text drawn as pictures.
        • The PDF/UA-1 rules that software can test, run with veraPDF, a free validator. Each rule that fails is put in one sentence.
        • Whether we can tag the file, and its price.

        What it does not decide

        • It does not decide whether a file meets the ADA, Section 508, WCAG or PDF/UA.
        • It does not judge what a person must: whether picture descriptions are right, whether the reading order makes sense, and colour contrast.
        • It does not replace reading the file with a screen reader.
