How to Split PDF

1 Upload the PDF documents you want divided.
2 Choose where the split points go — at fixed intervals, at every page or section, or at specific boundaries you nominate.
3 Run it; each piece is written as a complete standalone file rather than as a fragment that only makes sense beside the others.
4 Download the parts together as one ordered archive.

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.
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.
As a single archive when there are several, so one download gives you the whole set with predictable, ordered filenames. A single extracted range comes back on its own.
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.
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.
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.
Yes: free accounts process documents up to 5 MB each, which covers most reports and contracts but not a long scanned document at 600 DPI; 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.
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.
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.
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.
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.
No account, and nothing is kept: uploads are deleted from the workers shortly after the job finishes, nothing is read and nothing is indexed. Free accounts exist for history and batch size, not for access.
