Why does Word give me PDF/A-1b when my department asked for PDF/A-2b?

Because Word offers exactly one option and it is part 1. The checkbox says ISO 19005-1 compliant, and 19005-1 is PDF/A-1. There is no dropdown hiding a second choice. If you genuinely need part 2, export a normal PDF from Word and convert that file separately.

My university wants PDF/A but I wrote the thesis in LaTeX. What changes?

Quite a lot, and mostly for the better. The pdfx package handles compliance directly, and most LaTeX distributions embed fonts by default, which removes the commonest failure. The usual sticking point is an included figure carrying its own colour space, so check any EPS or PDF graphics you have imported.

Do I need to worry about tracked changes and comments before exporting?

Yes, and this catches people every year. Accept or reject every tracked change and delete all comments before you export, because both can survive into the PDF as annotations. A supervisor's marginal note appearing in a deposited thesis is not a compliance failure, but it is a conversation nobody wants.

Word says the export succeeded but a validator disagrees. What went wrong?

Usually a font that Word could not embed because its licence forbids it, most often a decorative or downloaded typeface. Word does not always warn you. Swap the offending font for a standard one and export again, since no conversion tool can override a licence restriction.

Does saving as PDF/A make my thesis accessible?

No. Word produces level b conformance, which covers appearance only. Accessibility lives in level a and needs proper heading styles, alternative text on every figure and a defined reading order. Using real Word heading styles rather than manually bolded text is the single most useful habit if accessibility is also required.

My embedded video and hyperlinks disappeared. Is that a bug?

No, that is the standard working. Embedded audio and video are forbidden in every part of PDF/A, so they are removed rather than preserved. Hyperlinks normally survive as annotations, though some readers stop treating them as clickable once the file is in archival mode.

How large should I expect the file to get?

Larger than a normal PDF, sometimes noticeably. Every font used has to be embedded, so a thesis mixing a serif body face, a sans-serif for headings and a maths font carries all three. If your repository has an upload ceiling, compress the images before exporting rather than compressing the finished archival file.

Can I combine several chapter files into one PDF/A?

Yes, but merge first and convert last. Merging separately converted archival files can produce a result that no longer validates, because the merge tool rebuilds the document structure. Combine the chapters into a single PDF, then run one conversion over the whole thing.

The repository rejected my file without saying why. Where do I start?

Run it through a validator before doing anything else, because the message is usually generic while the cause is specific. In our experience it is a missing colour profile or one unembedded font roughly three times out of four, and both are visible in a few seconds.

Should I keep the original Word file after submitting?

Absolutely, and back it up somewhere separate. The archival PDF is deliberately hard to edit, so if a correction is required after deposit you will want the source document rather than trying to reconstruct it. Keep the Word file, the exported PDF and the final archival copy.

How to Save a Word Document as PDF/A for Thesis Submission

In Word for Windows, press F12, choose PDF as the file type, click Options, and tick the box marked ISO 19005-1 compliant (PDF/A). That is the whole setting.

It is buried two dialogs deep with a name that mentions neither PDF/A nor archiving in the part people actually read, which is why every university library on the internet has a page explaining it. Your repository wants a format the software will not name plainly, and the deadline is Friday. Here is the route, plus the traps that fail a deposit after the export appears to have worked.

Finding the ISO 19005-1 compliant checkbox on Windows

Open the finished document and press F12 to bring up Save As.
Set Save as type to PDF.
Click Options, which sits below the file type dropdown and is easy to miss.
Tick ISO 19005-1 compliant (PDF/A) near the bottom.
Click OK, then Save.

One thing worth knowing before you go looking for alternatives: 19005-1 is PDF/A-1, and Word offers nothing else. There is no hidden dropdown with parts 2 and 3. If your department specifically wants PDF/A-2b, export an ordinary PDF here and convert that file afterwards with our PDF/A converter, which lets you pick the level.

Also select Standard rather than Minimum size for publishing. Minimum size downsamples images aggressively, and a thesis with figures in it deserves better than that.

Getting PDF/A on Mac without Word doing the work

Word for Mac has never offered the option. This is not something you have missed.

Three workarounds, in the order we would try them.

Export a normal PDF and convert it. Save as PDF from Word, then run the file through a converter that lets you choose the part. Fewest moving pieces, and it works the same on any machine.

Use LibreOffice. It is free, opens .docx perfectly well, and its PDF export has a proper Archive (PDF/A) option with a choice of parts. Check the formatting after opening, since complex layouts occasionally shift.

Use a university lab machine. Unglamorous, and if the deposit is tomorrow it is the most reliable option available.

Avoid the Preview route that older guides recommend. Preview can produce a PDF, but it does not reliably produce a compliant one, and you will not find out until the repository refuses it.

What breaks a Word to PDF/A conversion for a dissertation

The export usually reports success. The failures show up later, and they cluster around five causes.

Fonts with restrictive licences. Some typefaces are licensed in a way that forbids embedding, and Word will not always tell you. The fix is to change the font — no converter can override a licence. This is the most common single failure and it has a full guide in the fonts not embedded error.

Tracked changes and comments. Accept or reject everything and delete all comments first. Both can survive into the PDF as annotations.

Linked rather than embedded images. An image inserted as a link points at a file on your disk. Use Insert rather than Link to File, or the figure may not travel.

Equations from old add-ins. Legacy equation editors sometimes produce objects that convert badly. Check every equation in the exported file rather than assuming.

Chapters converted separately then merged. Merging archival files can produce something that no longer validates. Merge the chapters into one PDF first, then convert once.

Meeting the thesis repository upload format on the first attempt

Repositories tend to give a generic rejection message and leave you guessing, so check the file yourself before uploading.

Run the export through our PDF/A validator. It reads the file in your browser and reports the declared part, whether every font is embedded and whether the colour profile is present. That takes seconds and catches the two failures that account for most rejections.

Then look at the document itself. Open the archival copy beside the Word original and check the figures, the tables and the equations. Conversion strips whatever the standard forbids and carries on quietly, so the compliance check passing does not mean nothing changed.

Finally, read the requirement once more for a specific part number. A valid PDF/A-2b file arriving at a repository that accepts only PDF/A-1b gets refused, and the notice rarely explains that. The differences are set out in which conformance level you need.

If your thesis includes scanned material

Appendices with scanned permissions, historical documents or handwritten notes need separate handling.

A scan converted to PDF/A is fully compliant and completely unsearchable, because the standard never required a text layer. Examiners searching your appendix for a term will find nothing. Optical character recognition has to happen before archiving, not after, and the sequence is covered in turning scanned PDFs into PDF/A.

Before you submit

Keep the Word file and back it up separately. The archival PDF is deliberately awkward to change, so if the examiners want a correction you will want the source rather than a reconstruction. If you do end up needing to alter the deposited copy, editing a PDF/A file covers doing it cleanly, and what PDF/A actually is explains why the repository asked in the first place.
