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.
