DOCX section splitter

• Choose one local DOCX file and use Inspect sections to read its explicit section order.
• Choose Split selected sections and enter all, one section number, or a selection such as 1,3-5.
• Download the resulting DOCX or ZIP. Check the report and open the document to review numbering and pagination.
• Cancel or Reset terminates processing and clears the result.

Split a two-section report with a portrait introduction and a landscape table into two DOCX files with their inherited headers preserved.

• Sections are explicit OOXML section boundaries, not rendered pages. Continuous sections reflow when opened separately. List numbering and pagination may restart or change; there is no rendered-page split or layout-fidelity promise.
• 20 MiB compressed input; 1,000 ZIP entries; 16 MiB per entry; 64 MiB expanded package; 8 MiB per XML part and 16 MiB combined XML; 200,000 nodes per part and 400,000 combined nodes; 64 nesting levels; 50 sections; 60-second worker deadline.
• Combined selected packages are limited to 64 MiB expanded and 32 MiB compressed, with a 64 MiB final ZIP limit. Choose fewer sections if repeated shared resources exceed these limits.
• Only ordinary UTF-8, transitional DOCX packages with a final body sectPr are supported. Encrypted, macro-enabled and signed documents are rejected.
• Fields, bookmarks/ranges, footnotes/endnotes, comments, tracked changes, content controls, embedded objects, charts, alternate content and external relationships are rejected. Nothing is fetched, executed or uploaded.
• Shared style, numbering, settings, font resources and document properties remain. Unreferenced package parts, custom XML data and thumbnails are omitted. This is not redaction or metadata removal.
• Supported existing passive PNG, JPEG, GIF, BMP, TIFF, WMF and EMF image parts are copied unchanged, including their metadata. No image or font rendering occurs in this tool.
