Before you submit a PDF to a printer, a court, a journal or an archive, it pays to know what is inside it. This tool parses the file and reports its PDF version, page count and sizes, whether it is encrypted, which fonts it uses and whether they are embedded, how many images and form fields it has, its metadata, any PDF/A claim, and — if you ask — whether every page renders without errors.
Problems are flagged with plain-language explanations. The report is generated in your browser.

Frequently asked questions
Is this a PDF/A validator?
It reports the PDF/A claim and obvious violations (non-embedded fonts, encryption) but is not a certified validator like veraPDF.
Why do non-embedded fonts matter?
They make the document look different on machines without those fonts, and are forbidden in PDF/A.
Is my file uploaded?
No. Everything runs in your browser.
