Documenta Word Coniunge Quaestiones Frequentes
How does Merge Word join the files together?
+
Concretely, the documents are appended with their styles reconciled, so headings stay headings and the combined file is still fully editable rather than a stack of page images. Upload everything you want combined and the result comes back as a single file.
Can I control the order things are joined in?
+
Yes — drag the uploaded items into the order you want before starting. Order is taken from the list, not from the filenames, so "chapter2" sorting after "chapter10" is not a problem you have to solve first.
Does it matter if the inputs are different formats?
+
It does. Word documents keep text, styles and images as editable objects rather than as a fixed page image. Matching inputs take a fast, lossless path; mismatched ones have to be reconciled to a common format, which is slower and costs one encode.
Anything specific to Word when merging?
+
Yes — the document is a zip of XML, so text edits are cheap and the weight is almost always the embedded images. That is worth checking when the inputs did not all come from the same source.
How many files can I combine at once?
+
On the free tier a merge accepts two files at a time, which is deliberately higher than the single-file limit on other tools because merging one file is meaningless. A pass removes the cap entirely.
Is the merge lossless?
+
It is whenever the inputs already agree — the encoded data is copied straight through. It stops being lossless only when the inputs disagree and something has to be re-encoded to make them compatible, and even then it is one pass, not one per file.
What can I upload to Merge Word?
+
DOCX and legacy DOC, plus ODT, RTF and plain TXT. LibreOffice does the parsing, so anything it opens correctly on a desktop opens correctly here.
Is there a file size limit on Merge Word?
+
Yes: free accounts process documents up to 25 MB each, and since the text in a Word file is XML, anything near that ceiling is embedded images rather than writing. If a document is over it, the fix is almost always to downsize the images inside rather than to cut content.
Will Merge Word lower the quality of my Word documents?
+
The text, styles, headings, tables and lists are structured data and survive intact — they are not re-typeset. The only thing that can lose fidelity is an embedded image, and only if the operation you chose recompresses it.
Can I run Merge Word on several Word documents at once?
+
Yes. Documents are small and parse fast, so a batch of them is usually finished before a single video would have started.
Do tracked changes and comments survive?
+
Comments and tracked changes are preserved where the operation permits it, but treat them as review data rather than content: if you are sending the result outside your organisation, accept or reject them first, because they travel with the file.
Does Merge Word cost anything?
+
No. Merge Word is free with no account and no Microsoft licence required. Uploaded documents are deleted from the workers shortly after the job completes.
