What does the Split PDF by Page Range do?
Use this tool when you need a browser utility that copies selected pages into a new PDF in the order requested. It accepts one unencrypted PDF and an optional comma-separated page range and returns a new downloadable PDF containing only selected pages. Results are deterministic for the same input except where cryptographic randomness, current time, or a live provider response is part of the task.
Split copies pages; it does not edit page content
Use Split PDF to create a document from selected whole pages in their current form. Use PDF Organizer when the same operation also needs reordering, duplication, or rotation.
How do you use it?
- Open one unencrypted PDF no larger than the 100 MB total limit.
- Enter comma-separated pages or inclusive ranges such as 1-3,5,8; leave the field empty for every page.
- Select Process, confirm the exported page count, and download split.pdf.

Common errors and fixes
| Symptom | Likely cause | Fix |
|---|---|---|
| Processing reports a page outside the document. | The range contains zero, a negative number, or a number greater than the source page count. | Use one-based page numbers within the displayed document length. |
| The PDF cannot be opened. | The file is encrypted, damaged, incomplete, or not actually a PDF. | Unlock it with authorization or repair/export a valid copy before processing. |
Important behavior of Split PDF
Encrypted or damaged PDFs may need to be repaired or unlocked with authorization first.
