What is a PDF/A Validator?

A PDF/A validator is a tool that checks whether a PDF file meets the PDF/A standard (ISO 19005) — the international format for long-term digital archiving. It confirms that all required elements (fonts, color profiles, metadata) are correctly embedded and that no prohibited features (such as encryption or JavaScript) are present.

At PDFFixNow, you can validate PDF/A compliance online for free. Simply upload your PDF and the tool instantly checks it against the ISO standard and reports the exact conformance level (PDF/A-1b, PDF/A-2b, PDF/A-3, etc.) or explains why the file does not meet the standard. No Adobe Acrobat required, no account needed.

Confirm that government documents and official records are correctly archived for long-term digital preservation.
Check that financial reports, audit records and corporate filings comply with archiving regulations.
Validate medical records and healthcare documents before storing them in archival document management systems.

Tips for PDF/A Compliance

Always run a PDF/A validation check before submitting any document to a government body, court or regulator. A failed compliance check can cause your submission to be rejected, causing delays.

If you are creating new archival documents, target PDF/A-2b or PDF/A-3 rather than the older PDF/A-1b. The newer levels support transparency, JPEG 2000 compression, and embedded files for more flexible archiving.

Different organizations require different PDF/A levels. Check the specification of the system you are submitting to and make sure your document matches the required level (e.g., PDF/A-1b for older systems).

The most common reason PDF/A validation fails is missing or non-embedded fonts. When creating a PDF/A file, always set your PDF generator to embed all fonts completely rather than subsetting them.

Encrypted PDFs cannot be PDF/A compliant because the standard prohibits encryption. If your PDF is password-protected, use our Unlock PDF tool to remove the encryption before running the PDF/A validation check.

Always validate the output PDF/A file after conversion — not the source file. Even if your converter claims to produce PDF/A output, the resulting file may have minor compliance issues that only a validator will catch.

Frequently Asked Questions About PDF/A Validation

PDF/A is an ISO-standardized version of PDF (ISO 19005) specifically designed for the long-term archiving of digital documents. Unlike regular PDF, PDF/A files are fully self-contained — all fonts, color profiles, and metadata are embedded. Features that could compromise future access (such as encryption, external font links, JavaScript, and audio/video) are prohibited.

Many government agencies, courts, financial regulators and corporate archives require documents to be submitted as verified PDF/A files. Validation confirms that your PDF is truly self-contained and meets the archival standard — not just named with a PDF/A extension. A file that is not properly validated may be rejected during submission.

The validator supports all major PDF/A conformance levels: PDF/A-1a and PDF/A-1b (ISO 19005-1), PDF/A-2a, PDF/A-2b and PDF/A-2u (ISO 19005-2), and PDF/A-3a, PDF/A-3b and PDF/A-3u (ISO 19005-3). The tool detects and reports the exact level found in your document.

PDF/A-1 is the original archival standard (2005). PDF/A-2 extended it to support JPEG 2000, transparency layers and embedded PDF/A files. PDF/A-3 is the most flexible level and allows embedding of any file type (such as XML or CSV) alongside the PDF content. The “b” suffix means basic visual conformance; “a” means full accessibility conformance; “u” means Unicode-mapped text.

A failed validation means your PDF does not fully meet the PDF/A standard. Common reasons include: embedded fonts are missing or subset, the file uses encryption, it contains JavaScript, external color profiles are not embedded, or multimedia elements are present. The validation report will tell you the specific reason for failure.

To convert a regular PDF to PDF/A, you need a tool that re-encodes the file to embed all required elements. Adobe Acrobat Pro can do this via the Preflight tool. Free options include the LibreOffice export to PDF/A or online converters that offer a PDF to PDF/A conversion feature.

Yes. All uploads are protected with TLS encryption. Your PDF is processed on our secure servers and automatically and permanently deleted after validation. We never read, store or share your documents.

The validator accepts standard PDF files (.pdf). Upload any PDF you need to check and the tool will determine whether it meets PDF/A archival compliance standards.

PDF/A validation is commonly required by government agencies, courts, financial institutions, hospitals, universities and any organization that archives documents for long-term preservation. If you are submitting a document to any system that requires PDF/A format, running a validation check first ensures your file will not be rejected.
