Convert PDF to PDF/A Online — Long-Term Archiving
Introduction
Digital documents intended for long-term preservation must adhere to specific standards to ensure they remain readable and accessible for decades. PDF/A is an ISO-standardized version of the Portable Document Format (PDF) specifically designed for the archiving and long-term preservation of electronic documents. PDFscaler provides a free PDF to PDF/A converter online that transforms your standard PDF files into compliant archival documents in seconds.
Unlike regular PDFs, PDF/A files are self-contained, meaning they embed all necessary information — such as fonts, color profiles, and images — directly into the file. This eliminates dependencies on external resources that might become unavailable in the future. Operating 100% locally in your web browser, our PDF to PDF/A utility ensures that your sensitive legal, municipal, and corporate records are archived securely without ever leaving your device.
What This Tool Does
The PDF to PDF/A tool performs a comprehensive validation and restructuring of your PDF document to meet ISO 19005 standards. When you upload a file, our client-side engine scans the document for non-compliant elements, such as active scripting, external font references, and non-embedded color spaces.
The engine then rewrites the PDF metadata, embeds all required font subsets, and enforces standard sRGB color profiles. It strips away prohibited interactive elements to maximize future compatibility. The resulting PDF/A file is a robust, archival-grade document that is guaranteed to render identically across any compliant software or hardware, both now and in the future.
