Convert a PDF to PDF/A for archiving
Prepare a PDF for long-term storage.
Or drop a PDF here. Files stay on this device. Nothing is uploaded.
The tool checks the document against the PDF/A-2b requirements it can test, shows each problem with the pages concerned, and fixes what can be fixed automatically. It checks and converts, but it is not a certification: only a dedicated validator can confirm conformance.
How to convert a PDF to PDF/A for archiving
- Choose the PDF you want to archive.
- Read the list of problems the check found and the note on what it does not test.
- Select Fix automatically, add a title if the document has none, and confirm.
- Review what was fixed and what remains, then select Download.
What you get
A report you can read
Each requirement is listed as a problem, a warning or passed, with an explanation and links to the pages concerned.
Fixes that keep the page as it is
The conversion embeds missing fonts using a similar open font, adds an sRGB colour profile, writes the XMP metadata and a file identifier. It names every substitute font it used.
Clear about its limits
The report states what is not checked, such as the validity of font programs and file structure. The result reads “passes this tool's checks”, never more.
Undo in one step
If you do not like the result, one click takes the conversion back.
PDF to PDF/A: questions and answers
Does this guarantee a valid PDF/A file?
No. The tool tests a defined list of PDF/A-2b requirements and converts the file to meet them, and it tells you which ones it cannot test. For a legal or institutional archive, validate the result with the validator your archive uses.
What happens to fonts that are not in the file?
A similar open font is loaded and embedded in its place, for example Arimo for Helvetica or Arial. The result names the substitute, and you should check that the text still fits.
What cannot be fixed automatically?
Some problems need a decision from you or a different source file, such as encrypted content or features the standard forbids. They stay in the report as problems, with an explanation.
Is the file uploaded?
No. The check and the conversion run in your browser.
