2There is nothing to set: a PDF is split into single pages, and a Word document at its page breaks, or before each Heading 1 when it has none.
3Run it; each piece is written as a complete standalone file rather than as a fragment that only makes sense beside the others.
4Download each part as its own file. A paid plan adds one ZIP download with all of them.
Split Word FAQ
Is anything lost when a file is split?
+
No. Splitting is structural, not a re-render, so each piece carries the same content quality as the original. What can be lost is context — a cross-reference that pointed at a part now living in a different file.
How does Split Word divide the file?
+
Concretely, the document is divided at heading or page boundaries and each part is written as a full document with its styles intact, so the pieces are individually editable rather than fragments. Each piece comes back as a complete, self-contained file rather than a fragment that only makes sense next to the others.
Anything specific to Word when splitting?
+
Yes — the document is a zip of XML, so text edits are cheap and the weight is almost always the embedded images. Worth knowing when the pieces need to stand alone.
Is there a file size limit on Split Word?
+
Yes: free accounts process documents up to 5 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.
Can I run Split 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.
Why does a EPUB site host Split Word?
+
EPUB.to is built around the open eBook format — XHTML in a zip, reflowable by design, and readable on hardware nobody has thought about the layout for. A book is a zip full of markup, images and fonts, so almost every job people bring to an eBook site is really a job on one of those things. Split Word runs on the same upload and the same account as the conversions because that is where it is needed.
What should I do with the result once Split Word is finished?
+
The converter on this site moves books between EPUB, MOBI, AZW3, PDF and DOCX, so a title ends up on whatever hardware is actually going to read it. Doing that after Split Word means the conversion is made from the version you settled on, not from the one you were still fixing.
Is Split Word here the same tool the sibling sites run?
+
The engines are shared — the same toolchain, the same workers, the same limits. What a EPUB site adds is a view on reflow: which of these operations a reflowable book genuinely supports, and which ones only make sense on the fixed-layout media inside it. It also starts from one fact about the format this site is named after: the book is a zip of XHTML with a manifest, so the text costs almost nothing and every decision that matters is about the embedded images and font subsets.
Do I need an account, and does anything get kept?
+
No account is needed. Uploads and results are kept for about 24 hours, which leaves time to download the result, and are then deleted automatically; nobody reads, lists or indexes them. Several files in one job need a paid plan.
