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 PDF FAQ
Does the source format affect how it splits?
+
It does. PDF fixes the page: fonts, vectors, raster images and text coordinates are frozen so every reader sees identical layout. The internal structure is exactly what determines where a clean boundary can be placed.
Anything specific to PDF when splitting?
+
Yes — a PDF is an object graph, not a page image, so text stays selectable and vectors stay sharp no matter what happens to the raster content inside it. Worth knowing when the pieces need to stand alone.
How does Split PDF divide the file?
+
Concretely, the page tree is divided at the boundaries you choose and each part is written as a complete standalone document, with its own fonts subsetted in — so nothing depends on the original and text stays selectable throughout. Each piece comes back as a complete, self-contained file rather than a fragment that only makes sense next to the others.
Can I run Split PDF on several PDF documents at once?
+
Yes — upload the set and they process in parallel under one set of settings, which is the point of doing a document workflow here rather than clicking through a desktop reader.
Do bookmarks, links and form fields survive?
+
Outlines, internal links and annotations are preserved wherever the operation allows it. Digital signatures are the exception: any change to the file necessarily invalidates a signature, because that is precisely what a signature is for.
Is there a file size limit on Split PDF?
+
Yes: free use has a size limit per document, and the page tells you when a file is over it; Ghostscript and qpdf do the work. Scanned PDFs are the usual thing that exceeds it, and compressing the document first is normally enough to bring it back under.
Will Split PDF lower the quality of my PDF documents?
+
Text and vector artwork are objects rather than pixels, so they stay perfectly sharp at any zoom no matter what happens. Only the embedded raster images can degrade, and only if the operation you chose resamples them.
Why does a Word site host Split PDF?
+
WORD.to is built around the editable end of a document's life — the DOCX that is still being written, still being styled and still being argued over, before anyone flattens it for sending. Office files are containers full of other people's media — images, embedded audio, fonts — so the work people need on them is usually the work they would need on those contents anyway. Split PDF shares the upload, the caps and the account with the conversions for that reason.
What should I do with the result once Split PDF is finished?
+
The converter on this site takes documents out to PDF for sending, to images for embedding and to plain text for anything that has to read them programmatically, and back the other way. Doing that afterwards keeps the editable original around, which is the part you cannot get back once it has been flattened.
Is Split PDF here the same tool the sibling sites run?
+
The engines are shared — the same document toolchain, the same workers, the same limits. What a Word site adds is a view on what survives leaving the Office format and what does not, which is the question every one of these jobs actually turns on. It also starts from one fact about the format this site is named after: the document is a zip of XML, so text edits are cheap and the weight is almost always the embedded images.
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.
