A quick guide to Scan to PDF/A questions

What is PDF/A?

PDF/A is an ISO-standardized version of the Portable Document Format (PDF) specifically designed for the long-term archiving and preservation of electronic documents. Its purpose is to ensure that documents remain self-contained and perfectly readable in the future.

Why should I convert my PDF to PDF/A?

You should convert to PDF/A if you need to guarantee that your document will be readable and look exactly the same decades from now, independent of software or hardware changes. It's ideal for legal, archival, and historical documents.

What are the key differences between PDF and PDF/A?

PDF/A requires all fonts to be embedded, prohibits encryption and executable content (like JavaScript), and defines color spaces to ensure consistent rendering. It removes features that could hinder long-term preservation, making it more restrictive but also more stable for archiving.

Will converting to PDF/A change my document's appearance?

The goal of PDF/A conversion is to maintain the document's original visual appearance precisely. Any necessary changes, like embedding fonts or defining colors, are done to ensure consistent rendering over time, not to alter the layout or design.

Can I convert scanned PDFs to PDF/A?

Yes, scanned PDFs can be converted to PDF/A. If the scanned PDF contains only images of text, the PDF/A standard (specifically PDF/A-2b or PDF/A-3b) allows for this. For better searchability, you might consider performing OCR on the scanned PDF before or during the PDF/A conversion process.

Is my document secure while it's converted to PDF/A?

We prioritize the security of your documents. Files travel over secure HTTPS and are processed automatically with no human review. They are saved to your private file manager; free-account files are removed 30 days after their last activity, and you can delete them sooner.

Do I need to install software to convert PDF to PDF/A?

No, our Convert PDF to PDF/A tool is an online application. You can use it directly in your web browser without needing to download or install any software on your computer or device.

Will encrypted PDFs be converted to PDF/A?

No, PDF/A explicitly disallows encryption to ensure long-term accessibility. If your PDF is encrypted, you will need to remove the encryption (unlock the PDF) before you can convert it to a valid PDF/A file.

What happens if my PDF contains features not allowed in PDF/A?

Our tool will attempt to either remove these disallowed features (like JavaScript or embedded files) or convert them to a static representation that complies with the PDF/A standard. The goal is to make the document compliant without losing essential content.

Are there different versions of PDF/A?

Yes, there are several parts and conformance levels of the PDF/A standard (e.g., PDF/A-1a, PDF/A-1b, PDF/A-2a, PDF/A-2b, PDF/A-2u, PDF/A-3a, PDF/A-3b, PDF/A-3u). Each specifies different levels of compliance and allowed features, with 'a' meaning accessible, 'b' meaning basic, and 'u' meaning Unicode.

What is the maximum file size I can convert to PDF/A?

Our online tool is designed to handle a wide range of PDF file sizes for conversion. While very large or complex documents might take a bit longer, most common file sizes can be efficiently processed.

Do I need an account to convert PDF to PDF/A?

No. Converting PDF to PDF/A is free and works as a guest with no account needed; just upload your file. A free account is optional for saving files, and guests get 5 free files before one is asked for.

Does the PDF/A file have a watermark?

No. PDFBEAR never adds watermarks, so your archival PDF/A file stays clean and compliant.

How long does the PDF to PDF/A conversion take?

Most files convert in a few seconds. Larger or more complex documents may take slightly longer.
