Frequently Asked Questions

Is it safe to split my PDF files here?

Yes, absolutely. Your privacy is our priority. One23PDF processes all your files directly in your web browser. Your PDF is never uploaded to our servers, ensuring your data remains 100% confidential and secure.

Can I extract specific, non-consecutive pages?

Yes. You can specify exact pages or ranges. For example, a rule like '1, 5, 8-10' will create a new PDF containing only pages 1, 5, 8, 9, and 10 from the original document.

What does the 'every:N' rule do?

This is a powerful feature for breaking large documents into fixed-size chunks. For example, 'every:2' on a 10-page PDF will create five separate 2-page PDFs (1-2, 3-4, 5-6, 7-8, 9-10).

What happens to the original PDF file?

Your original file remains completely untouched on your device. Our tool creates new, split PDF files based on your rules, leaving the source document as it was.
