Archive Documents for Long-Term Preservation

PDF/A conversion tool is designed for storing important documents that need to remain accessible for many years. Unlike a standard PDF, a PDF/A file includes all the resources required to display the document correctly, including embedded fonts and essential formatting information. This reduces the risk of missing fonts or compatibility issues in the future. It is a reliable format for contracts, financial records, legal documents, medical files, business reports and other records that require long-term storage. If you have scanned papers and you want to convert them into PDF/A, use the OCR PDF tool and convert them into PDF/A for better results.

Create Archive-Ready Files That Meet Compliance Standards

Many government departments, courts, educational institutions and business organizations require documents to be submitted in PDF/A format because it follows internationally recognised archiving standards. The tool creates PDF/A-compliant files by preserving the document structure and required metadata while maintaining the integrity of the original content. As PDF/A does not support certain features such as encryption, password-protected files should be unlocked before conversion. If your document is scanned, using OCR tool can also make the archived file searchable while keeping it compatible with PDF/A standards.

Preserve Document Quality with Secure Online Conversion

Converting a PDF to PDF/A does not change the visible content of your document. Text remains selectable, images keep their original quality and the overall layout stays intact with the source file. The converter simply adjusts the internal file structure to meet PDF/A requirements for long-term preservation. It works entirely in your web browser without requiring software installation or account registration. Files are transferred through a secure encrypted connection and are automatically removed from the server after processing to help protect your privacy. Most documents are converted within seconds, producing a high-quality PDF/A file that is ready for archiving, sharing or official submission.

FAQ

Frequently asked questions

What is PDF/A and why would I convert to it?
PDF/A is an ISO-standard version of PDF built for long-term archiving, so a document stays readable and looks the same decades from now. It embeds fonts and forbids features that could break over time, like external links and encryption. Governments, courts, and libraries often require PDF/A because it guarantees the file is self-contained and reliably reproducible.
How do I convert a regular PDF to PDF/A?
Upload your standard PDF and the tool embeds the necessary fonts, flattens unsupported elements, and writes the metadata required by the PDF/A standard. You then download a compliant archival copy. The process keeps your visible content and layout intact while adjusting the underlying file so it meets the format's rules for self-contained, future-proof documents.
Is converting to PDF/A free and without watermarks?
PDF/A conversion is free, requires no account, and adds no watermark to your archival file. You can convert as many documents as you need and download each compliant copy directly. It works in any modern browser across Windows, Mac, Linux, Android, and iPhone, so archiving records does not depend on any specific desktop software.
Does PDF/A conversion change how my document looks?
Your visible content stays the same, since PDF/A preserves the page layout, text, and images exactly as they appear. The changes happen underneath: fonts are embedded so they never go missing, and features that are not allowed for archiving are flattened or removed. The result opens and prints just like the original but is now self-contained and standard-compliant.
Can a password-protected PDF be converted to PDF/A?
PDF/A does not permit encryption, because an archived file must remain openable without a key far into the future. If your PDF is protected, remove the password first using our unlock tool on a document you own, then convert the open copy. The resulting PDF/A will be readable indefinitely without depending on a stored password.
Which PDF/A level should I use for compliance?
Most archiving and submission requirements are met by common conformance levels such as PDF/A-1b or PDF/A-2b, which ensure the document reproduces reliably. Check the specific rule you must satisfy, since courts and agencies sometimes name a level. If none is specified, a widely supported baseline level is the safest choice for general long-term storage and record keeping.
