Unlike cloud-based services that require uploading your documents, our tool processes everything locally in your browser. Convert your PDFs to PDF/A-1b, PDF/A-2b, or PDF/A-3b format — all on your own device. No uploads, no watermarks, completely private, and ISO-compliant.
What is PDF/A?
PDF/A (PDF for Archiving) is a specialized version of PDF designed for long-term preservation of electronic documents. Unlike standard PDFs, PDF/A removes features that could cause issues during future rendering, such as external font links, JavaScript, encryption, audio/video content, and external content references. All content must be self-contained and embedded within the file.
