What does PDF Splitter Online do?

Split large PDFs into smaller files without desktop software. Split PDF divides one document into smaller files by page ranges, bookmarks, size limits, or text triggers—whatever matches your workflow.

When to use PDF Splitter Online

Extracting a single chapter from a textbook PDF
Separating combined invoices by client
Breaking a scanned book into individual page PDFs

Use custom ranges when you need chapters or invoices separated precisely. Extract-all mode creates one PDF per page, ideal for bulk archiving.

Password-protected inputs can be split after you unlock them with the correct password. Each output is a standard PDF compatible with Adobe Reader and mobile viewers.

Download results individually or as a ZIP when multiple parts are generated.

Siliph split tools divide PDFs by range, bookmark, size, or text trigger entirely in the browser with encrypted transfers at each step. Generated parts are auto-deleted within two hours on the free plan, and splitting starts immediately without signup.

Guide for this use case

PDF Splitter Online extracts only the pages you need, keeping fonts and signatures intact. Use custom ranges like 1-5, 8, 12-14 when a client requests specific exhibits.

Split-every-page mode is ideal for bulk archiving of scanned receipts — each page becomes its own PDF in a ZIP download.

If the source PDF is password-locked, unlock it first with the correct owner password, then split. Split outputs are standard PDFs compatible with mobile viewers.
