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
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 choose where the split points go?
+
No. A PDF is split into single pages, and a Word document at its page breaks, or before each Heading 1 when it has none.
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 do I get the pieces back?
+
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.
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.
What can I upload to Split PDF?
+
Any standard PDF, including ones produced by a scanner, by a word processor or by a print driver. Files with an owner password that only restricts editing are handled; files that need a user password to open are not, and we do not attempt to break encryption.
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.
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.
Does Split PDF cost anything?
+
No. Split PDF is free without an account, and nothing is added to the document. The upload and the result are deleted automatically about 24 hours after the job, which leaves time to download the result.
