About This Tool
PDF/A is the ISO standard for long-term document archiving. This tool currently cleans up and compresses the file structure in preparation for archiving; it does not yet produce validated PDF/A output, so check the result with a PDF/A validator such as veraPDF before relying on it.
All conversion happens locally in your browser, ensuring your documents remain private.

Frequently Asked Questions
Which PDF/A level should I use?
PDF/A-2b is recommended for most uses. Use 1b for maximum compatibility or 3b if you need embedded files.
What makes PDF/A different?
The PDF/A standard requires files to be self-contained, for example with embedded fonts and no encryption. Output from this tool is not yet validated against the standard, so check it with a validator.
Can I convert back from PDF/A?
PDF/A files are standard PDFs and can be opened normally. The archival features add restrictions, not limitations.
