Frequently asked questions
Can I split a PDF by a target file size?
Yes. Enter a maximum size such as 5 MB or 10 MB, and the tool splits your PDF into consecutive parts that each stay under that limit, ideal for email or upload caps.
Can I split by page count or number of documents instead?
Absolutely. Choose to break the PDF every N pages or into an exact number of equal documents. Pick whichever mode matches how you want the pages grouped.
Is it safe to upload a confidential PDF?
Your file is uploaded over an encrypted connection and processed on a secure server, then you download the results. Use it for sensitive documents with confidence, but avoid sharing the download links publicly.
Is there a file size limit, and does it work on mobile?
The splitter handles large, multi-hundred-page PDFs, and very big files simply take a little longer. It runs in any modern browser, so you can split PDFs on a phone, tablet, or desktop.
Does splitting reduce the quality of my pages?
No. The original pages, text, images, and formatting are copied exactly into the new files. Splitting only divides the document; it never re-renders or compresses your content.
