Free tool · No account · Nothing to install
Most teams cannot answer the first question a document accessibility plan needs: how many PDFs are published, and where are they linked from. A crawler can answer it in about a minute, because the files are already public.
You get the full list, not a teaser: the crawler walks the whole site, and the report names every file it found, the pages linking to each one, and an automated check on the ten most-linked documents.
One live crawl per domain per day. If somebody scanned this site today, you get that result instead of the site being read twice.
Count, claim, switch
01This tool
A crawler reads your public pages and lists every PDF they link to. No install, no account, no permission needed to read what is already published.
02Free plan, 1 domain
Verifying the domain turns a one-off count into a monitored inventory: more pages, repeat checks, source-change alerts, and conversion into private drafts.
03When you are ready
The observe-only script points an existing PDF link at the approved accessible version, and finds the files a crawler cannot see. It changes nothing until you publish.
The monitoring script covers those, and is also the only way to switch a live link to an accessible version.
Counts describe the files this scan opened. Read what to do with them.
How the crawler behaves
The scanner identifies itself as Mozilla/5.0 (compatible; DocAccessible-SiteScan/1.0; +https://docaccessible.com/tools/website-pdf-scanner), the same shape Googlebot and Bingbot use, so a firewall that only checks for that prefix does not mistake an accessibility crawler for something worth blocking. It paces its requests, follows links rather than guessing URLs, and never signs in or submits a form. It walks the site once and opens at most 10 documents.
It does not apply robots.txt. That file governs search indexing, and this tool answers a question about your own published documents on your behalf. The one rule above everything is a direct request: ask us not to scan a domain and we refuse it permanently, whoever asks afterwards.
One live crawl per domain per day is shared by everyone who asks about that domain, so the site is read once no matter how many people run the tool. If you would rather we did not read your site at all, contact us and the domain goes on a refusal list that takes effect immediately.
A checked PDF is downloaded, scanned for malware, audited out of process, and discarded. What is kept is the list of public URLs and the findings, for seven days.
Questions
It reads the website the way a search engine does: it starts at the homepage and the sitemap, follows links on that domain, and records every link or embed that points at a PDF. Nothing is installed, and nothing is guessed at. A URL nothing links to is not found, because looking for it would mean probing a site rather than reading it.
No, and it is better to say so plainly than to bury it. robots.txt tells search engines what to index; this tool answers a question about your own published documents, on your behalf, and a rule written years ago for search crawlers should not decide whether you can count your own PDFs. The scanner reads only pages the site links to, identifies itself by name, paces its requests, never signs in or guesses URLs, and stores no documents. If you would rather it never visited your domain, tell us and we will refuse it permanently, which no request can override.
It walks the site once, at about four requests a second at its fastest, and opens up to 10 PDF files. One live crawl per domain per day is shared by everyone who asks about that domain, so a site is read once however many people run the tool, and a second request inside that window is answered from the first scan's results.
Opening a file costs the site bandwidth and costs us processing, so the free scan opens the ten most-linked documents, which are the ones most visitors actually meet. Every other file is listed with its URL and where it is linked from, and the report says plainly which ones were opened.
No. Automated checks find missing tags, missing titles, missing language, and structural failures. They cannot tell whether the reading order matches the page, whether a table's meaning survives, or whether a description is useful. Those need a person, and the report says so next to every count.
The scanner only reads pages that are already public, so technically yes, and the report is about published URLs rather than anything private. If you run the site, connecting the domain is better: an owner-verified crawl reads more pages, monitors for changes, and can turn a file into a remediation draft.
Two things. It sees links a crawler cannot: pages built by JavaScript, pages behind a login, and files linked only from a search result. And it is the only way to switch a live PDF link to an approved accessible version, which no crawler can do from the outside.
The list of public URLs, the automated findings, and a salted hash of the requesting address for abuse reports. The report expires after seven days. No PDF from the scanned site is stored: a checked file is downloaded, audited, and discarded.
Contact us and we will add the domain to the scanner's refusal list. It takes effect immediately, applies to everyone, and nothing overrides it.
