About PDF/A Standards

ISO 19005

PDF/A is a specialized ISO-standardized version of PDF specifically engineered for reliable long-term document preservation:

1

PDF/A-1

The foundation standard requiring complete font embedding and prohibiting transparency. Offers maximum compatibility across viewing platforms for reliable long-term preservation.

2

PDF/A-2

An enhanced standard that supports JPEG2000 compression, transparency effects, document layers, and nested PDF attachments while maintaining strong archival compliance.

3

PDF/A-3

The most versatile standard, allowing attachment of any file format within the PDF/A document. Ideal for preserving original source files alongside the final document in digital archives.

Our intelligent conversion engine automatically identifies and repairs common compliance issues, ensuring your document meets all requirements of your selected PDF/A standard without manual intervention.

Expert tips for creating perfect PDF/A archives

1

Select PDF/A-1b for maximum compatibility with archival systems, PDF/A-2b when you need transparency and layers, or PDF/A-3b when including source files like spreadsheets alongside your document.

2

Verify font embedding

Always enable complete font embedding to ensure your text appears exactly the same regardless of which system opens your document, even decades into the future.

3

Select appropriate color profiles

Choose sRGB for digital viewing, CMYK for documents intended for professional printing, or grayscale to minimize file size while maintaining excellent readability.

4

Run validation checks

Always validate your PDF/A files after conversion to identify and resolve any compliance issues that might prevent acceptance by archival systems or regulatory bodies.

5

Enhance document metadata

Include comprehensive metadata with title, author, creation date, subject, and keywords to improve searchability and ensure your documents remain discoverable in digital archives.

6

Maintain original versions

Always preserve your original PDF alongside the PDF/A version in your own storage system, especially if you might need to make edits to the document in the future.

Frequently asked questions about PDF/A conversion

Is your PDF/A converter completely free to use?

Yes, our core conversion service is completely free to use. You can convert your PDFs to any PDF/A standard without registration or hidden fees. For advanced features like detailed validation reports, batch processing, or enterprise-level integrations, we offer premium subscription options.

Will my document look different after converting to PDF/A format?

PDF/A standards focus on visual fidelity and consistent rendering. In most cases, your document will look identical to the original. However, certain elements like transparency may be flattened, and fonts will be embedded to ensure long-term visual consistency. These changes preserve how your document appears rather than altering it.

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

Our standard service supports documents up to 100 MB in size. For larger documents or bulk conversions, we recommend using our batch processing feature which efficiently handles large document collections. Enterprise users can request custom limits for extremely large archiving projects.

How do I know which PDF/A standard version to choose?

Select PDF/A-1b for maximum compatibility with all PDF/A-compliant systems and when simpler documents without transparency are sufficient. Choose PDF/A-2b when your document contains transparency, layers, or JPEG2000 images. Use PDF/A-3b when you need to embed source files (like Excel spreadsheets or Word documents) within your archival PDF.

Do I need to download software to convert my PDFs to PDF/A?

No software installation is required. Our PDF/A converter runs entirely in your web browser, making it accessible from any device with internet access. The actual conversion takes place on our secure servers, ensuring consistent, high-quality results regardless of your local system's capabilities.

How are document metadata and properties handled during conversion?

Our converter intelligently preserves existing metadata from your original PDF and enhances it with standardized XMP metadata fields required for PDF/A compliance. You can also add or edit title, author, subject, keywords, and other metadata during the conversion process to improve discoverability in digital archives.

Can I convert scanned paper documents directly to PDF/A?

Yes, scanned documents can be converted to PDF/A format, but we strongly recommend performing OCR (Optical Character Recognition) first. This makes the text searchable and extractable, greatly enhancing the document's usefulness in digital archives. Our tool can process existing scanned PDFs, whether they've been OCR'd or not.

How can I verify my document meets PDF/A standards after conversion?

Our converter includes an optional validation feature that thoroughly checks your document against all requirements of your selected PDF/A standard. The validation report highlights any compliance issues and provides recommendations for fixing them. This ensures your document will be accepted by institutional archives, courts, and regulatory bodies.
