How we handle your data

Office to PDF/A

Convert Office and OpenDocument files to PDF/A-2b when a process step, portal or client asks for an archival PDF/A upload. Your file stays in your browser.

Choose your document

Choose a DOCX, XLSX, PPTX, DOC, XLS, PPT, ODT, ODS, ODP or RTF file and convert it to PDF/A. The first conversion prepares the local Office engine and may take a moment; the next file on this page is faster.

Local limit: 10 MiB per document

Choose a document, then convert it to PDF/A.

Processing happens on this device. Keep this tab open until your PDF/A is ready.

Try an example

A two-page PDF/A-2b file with embedded fonts, the amount 148.50 and Russian text. Archive validators may apply stricter rules; check yours if compliance is mandatory.

Download sample DOCX

Select the downloaded sample and convert it. A two-page PDF/A-2b file with embedded fonts, the amount 148.50 and Russian text. Archive validators may apply stricter rules; check yours if compliance is mandatory.

What to expect

Text, images and page layout are converted together. Fonts and complex formatting may differ from your Office editor; check your PDF before sharing.

The PDF is saved as PDF/A-2b for long-term archiving: fonts are embedded, the color profile is included and the file identifies itself as PDF/A. Spreadsheets are fitted to one page width. This page does not run a formal PDF/A validator; if your archive requires proof of compliance, check the file with its validator.

Large documents may exceed your device’s available memory. If conversion fails, try a smaller document or another device.

Help with conversion

The converter does not start

Check your connection while the converter prepares itself, then retry. This converter needs a modern browser and sufficient memory.

My document could not be converted

Open the document in your editor and save a new copy. Password-protected, damaged or unsupported files may fail. The input limit is 10 MiB and the PDF output limit is 20 MiB.

Processing takes too long

Preparing the converter stops after two minutes; conversion stops after one minute. You can cancel during processing and restart with a smaller document.

A practical guide

Office to PDF/A for portals that require PDF/A

  1. Upload the DOCX, XLSX, PPTX, ODT or RTF file the portal asks for.
  2. Convert it to PDF/A-2b on your device.
  3. Upload the PDF/A and confirm the portal accepts it.

Try this example

Convert a three-page DOCX tender form to PDF/A before a portal upload; the PDF/A should keep all three pages and the signature table.

Before you start: Some portals demand a specific PDF/A part or run strict validators; check their requirements and validate if compliance is mandatory.
