Future packageA later design would remap word/_rels/document.xml.rels and could hash identical word/media bytes.A server merge would need the files first. This page does not send them.Copying between open documents does not use this page.

How this page works

  1. Read the planned status

    Merge is not currently available. This route is not the splitter wearing a different title.

  2. Do not expect a result

    Choosing a file or clicking the button does not build a merged .docx and does not upload anything.

  3. Use the splitter for a real task

    The splitter page can divide one .docx locally. It does not merge files.

Under the hood

A merger is not currently available. This is a later design, not a function you can run, and nothing is uploaded. A future local JavaScript tool, not WebAssembly, would append word/document.xml bodies in a chosen order. It would remap ids in word/_rels/document.xml.rels so styles, headers, and pictures do not collide. Identical word/media bytes could be kept once by a content hash. That hash would miss a chart stored in its own chart part rather than word/media. [Content_Types].xml would list every remaining part. Basic styles and whole tables could be carried over, but the same style id can differ between files, so conflicts would not be lossless. Numbering, fields, and section breaks could change. No batch-size limit is published, because the tool does not exist, and the page does not call the missing tool unlimited. The 100 MB compressed and 250 MB expanded limits belong only to the splitter that already runs.

Questions

Can I merge files here?

No. Merge is planned and not currently available. The button does not produce a document.

Would a future merge be lossless?

No such promise is made. Remapping relationship ids and keeping basic styles and tables would still leave style conflicts and some chart parts unresolved.

Are charts just files in word/media?

No. Some pictures live under word/media. A chart can live in a chart part referenced from the document, so a media hash would not cover every chart.

Is there a batch limit?

None is published, because the merger does not run. That is not a claim of unlimited files.
