How this tool works
PDF/A Conversion: a practical guide
PDF/A needs more than a filename or producer label: a converter must satisfy the chosen conformance requirements and a validator must check the output.
Tested example — 19 October 2026
The automated check confirms that the processor rejects the request as unavailable instead of relabeling a PDF.
Expected result: the operation rejects the request as unavailable. No empty or disguised conversion is offered.
Test environment: Actual unavailable-processor rejection verified by the automated suite. Representative sample; inspect your own output.
Check the result
Conversion is unavailable in this build. No file is generated or presented as PDF/A. Use an office application with PDF/A export and validate it with veraPDF.
Files and privacy
The public tool processes selected documents in your browser. It does not send document bytes to a conversion server. The page and its bundled libraries still download from this website. Keep the original, use an up-to-date browser and inspect your output before sharing it. See the privacy policy for hosting and support information.
If processing fails
Read the displayed error. Confirm the file type, page numbers and required settings. Try a smaller document or split a large file into groups. A scanned page needs OCR before text extraction. Do not interpret an error as a successful conversion; no empty or disguised result is provided.
