Merge Office Files to PDF: File Types, Order and a Real Test

Merge Office files to PDF when a report, a budget and a slide deck should reach the reader as one document. Upload Word, Excel, PowerPoint, OpenDocument, RTF or CSV files together, and the tool converts each one and joins the results into a single PDF. Pages follow the order you added the files in.

Which file types can be merged?

The tool takes DOC, DOCX, ODT and RTF text documents, XLS, XLSX, ODS and CSV spreadsheets, PPT, PPTX and ODP presentations, and ODG drawings. Mix them however you like in one job, say a Word report followed by an Excel appendix.

Our server converts each file with LibreOffice's PDF export, then your browser joins the converted PDFs page by page. That join step decides what survives in the merged file, as you'll see in the test below.

How the file order is decided

The merged PDF starts with every page of the first file in the list, then the second file's pages, and so on. Files you add later go to the end.

You can't drag the list into a new order, and it's never sorted by name or date. To move a file to the end, delete it and add it again.

What the merged PDF contains

In October 2026 we merged three files: a 4 page A4 Word report with three headings, a table of contents and a link to its Results section, then test.xlsx, then a two slide 16:9 presentation. That gave us an 8 page merged PDF of 62.0 KB.

SourcePages in the merged PDFPage size in points
report-a4.docx1 to 4595 x 842 (A4 portrait)
test.xlsx5 and 6595 x 842
slides-16x9.pptx7 and 8720 x 405 (16:9 slide)

Every page keeps its source's size, so the slides sit wider and shorter between the A4 pages. If the PDF is going to the printer or needs one page size, even them out with Resize PDF afterwards.

Links survive the join, bookmarks don't

Converted on its own, the Word report had 3 bookmarks (Background, Method and Results) and 4 working links on page 1, from the table of contents and the Results link. In the merged PDF the bookmarks were gone. In November 2026 we merged a new 4-page report with three contents links and test.xlsx, and all three links on page 1 still opened their sections on pages 2, 3 and 4.

If a reader has to jump around a long report by bookmarks, send the Word document's own PDF from Word to PDF along with the merged file.

Speaker notes and hidden slides are left out

A presentation adds one page per visible slide and nothing more. We merged a Word file with a three slide presentation, every slide with speaker notes and the second one hidden. The merged PDF had 6 pages (4 from the document, 2 slides) and none of the notes text.

Need the notes in the packet? Print them from PowerPoint with its notes pages layout to a PDF and add that file with Merge PDF. And if a hidden slide belongs in the PDF, unhide it in PowerPoint before you upload.

A file that fails stops the whole merge

We also uploaded the report with a password to open. The server refused it right away with "The file is not a valid .docx document. It may be damaged or renamed.", and since the page only joins the PDFs once every file has converted, the other files didn't give a merged PDF either.

Remove the password in Word, save the file and add all the files again.

What happened when we tested Merge Office to PDF

We uploaded two small test files, test.docx (25.7 KB) first and test.xlsx (5.7 KB) second. The download, MergedOfficeToPDF.pdf, was 39.7 KB with 3 pages, the Word document's pages first and the spreadsheet's after them. Tested in October 2026.

When to convert first and merge later

This tool is the right pick when the files are ready and their order is settled. In these cases, convert them with Office to PDF first and join the PDFs in Merge PDF:

  • You need to change the order after uploading, or move single pages instead of whole files.
  • Some parts are already PDFs, such as a signed form or a scanned receipt.
  • You want an empty separator page between documents, which you can make with Blank PDF.
  • The batch is large, because Office to PDF still converts the files that work when one fails.

If all your files are one type, Merge Word to PDF, Merge Excel to PDF and Merge PowerPoint to PDF do the same job. Fonts the server doesn't have get replaced, so a document can look a little different from how Microsoft Office shows it.

Limits and privacy

Each file can be up to 25 MB. The tool is self-hosted with no outside conversion service, and you don't need an account.

Uploaded files and their converted PDFs get deleted automatically within two hours.

Frequently Asked Questions about merging Office files to PDF

Will the bookmarks of my Word document work in the merged PDF?

No. The join keeps the pages but drops the bookmarks. Links inside the document still lead to their sections, since each one is carried over with the page it points to.

Can I change the order after uploading?

Not by dragging. Delete a file and add it again to move it to the end of the list.

Why do the pages of my merged PDF have different sizes?

Each file keeps its own page size, so A4 documents and 16:9 slides end up side by side. Resize the merged PDF if you need one size.

Are spreadsheet formulas still live in the PDF?

No. The PDF shows the cell values as they print, and you can't edit any of it as a spreadsheet.

What should I do if pages are blank or cut off?

Check each file's print area, orientation, scaling and margins in your Office program, then upload the fixed files again.
