Overview
Split a PDF into pages or page ranges
Splitting a PDF means extracting one or more pages from a source document and saving them as separate files. It is the opposite operation of merging. The most common reasons to split are: pulling a single page out of a long report, separating chapters into their own files for distribution, removing pages you do not want to share, or breaking a large PDF into smaller chunks that fit upload limits.
ToolHub PDF Split runs entirely in your browser. The source PDF never leaves your device. You can extract custom ranges with a simple syntax like 1-3, 5, 7-9 or split into one file per page with a single click.
Step-by-step
How to split a PDF
- 1
Drop in your PDF
Upload a single PDF. The page count is read locally and shown so you know what range you are working with. - 2
Pick a split mode
Custom ranges lets you extract specific pages or ranges into separate files. Every page splits the document into one file per page automatically. - 3
Define your ranges
For custom mode, type comma-separated tokens.1-3extracts pages 1, 2, and 3 into one file.5extracts page 5 alone.1-3, 5, 7-9creates three separate output files. - 4
Download
Single output downloads instantly. Multiple outputs are bundled into a ZIP file with descriptive names likedocument-pages-1-3.pdf.

Custom ranges
Use this when you know exactly which pages you want. Useful for extracting a chapter (pages 23 to 67), pulling out an appendix (pages 100 to 110), or cherry-picking specific pages from a long document. Every comma-separated group becomes one output PDF.
Every page
Use this when you want to break a PDF into its individual pages. Common when you receive a multi-page scan and need each page as its own file for tagging, archiving, or sharing.
Use cases
When to split a PDF
Sharing a single page from a long document
Pull out the page you actually need to send instead of forwarding the whole 50-page report.
Removing sensitive pages before sharing
Extract only the pages safe to share. The rest stays private with you.
Fitting upload size limits
If a PDF is too large to upload to a portal, split it into smaller files that each fit within the limit.
Separating receipts or invoices
If you scanned all of January's receipts as one PDF, split into individual files for accounting.
Distributing chapters of a book or guide
Authors and educators often share specific chapters instead of the entire document.
Submitting forms with mixed pages
Some online forms require each section as a separate upload. Split a single source file to comply.
Common questions
What if I enter an invalid range?
The splitter validates your input live. If you ask for a page that does not exist (like page 50 of a 30-page document), or use invalid syntax, you get an inline error message before any processing starts. Nothing is split until the input is valid.
Will form fields and links survive splitting?
Yes for most cases. Pages are copied with their content intact including embedded forms, fonts, and links. Cross-page links that point to a page not included in the output will simply do nothing when clicked.
Can I split a password-protected PDF?
Not directly. You need to remove the password first using your PDF reader, then split the unlocked copy.
What naming pattern do output files use?
Single page outputs are named like filename-page-5.pdf. Range outputs use filename-pages-1-3.pdf. This makes it easy to identify each part later.
