Is my PDF uploaded to your servers?

No. Split PDF runs entirely in your browser. Your file is read into memory locally and split with pdf-lib — there is no upload step.

How do I write a page-range expression?

Use commas to separate ranges and dashes for inclusive ranges. For example, 1-3, 5, 7-9 splits a document into three new PDFs: pages 1–3, page 5, and pages 7–9.

What does 'Every N pages' do?

Every N pages chunks the document into equal-size pieces. With N=10 on a 35-page PDF you'll get four files: 1–10, 11–20, 21–30, and 31–35.

Why would I split a PDF?

Common reasons include sharing a single chapter from a book, sending only the signature page of a contract, separating a scanned batch into individual receipts, or splitting a long report to fit email size limits.

Does splitting affect quality?

No. Pages are copied losslessly. The original streams, fonts, and images are preserved exactly in each output file.

Can I split very large PDFs?

Yes. Because there's no upload, file size limits depend only on your device's RAM. Splitting tends to be lighter on memory than merging because each chunk is written and released as it's produced.

Does Split PDF work on iPhone and Android?

Yes. Split PDF runs in any modern mobile browser — Safari on iOS, Chrome and Firefox on Android — with no app install. For very large PDFs, prefer a desktop browser to give the split more memory headroom.

Is Split PDF free to use?

Yes. Split PDF is fully free — no signup, no watermark, no page or output count limit. Converter.Plus is funded by ads, never subscriptions.
