PDF Splitter

Split a PDF into multiple files. Download as a ZIP archive.

How to split a PDF file online for free: no uploads required

AlteredIdea's PDF Splitter gives you full control over how a PDF is divided. You can extract every page as its own document, or define custom page ranges so each segment becomes a separate PDF. Everything runs in your browser: no files are sent to any server, making it safe for confidential documents.

The split PDFs are packaged into a ZIP archive for convenient download. This is useful when you need to distribute specific sections of a large report, isolate invoices from a combined statement, or share individual chapters of a book without sending the entire document.

Frequently Asked Questions

How do I split a PDF into individual pages for free?
Upload your PDF to AlteredIdea PDF Splitter, select 'Split All Pages', and click Split PDF. Each page is saved as a separate PDF inside a ZIP file that downloads automatically.
Can I split only specific pages from a PDF?
Yes. Use 'Split by Ranges' mode and enter page ranges like '1-3; 5-7'. Each range becomes its own PDF file inside the downloaded ZIP.
Are my files uploaded to a server?
No. All splitting is done locally in your browser. Your files never leave your device.
What is the output format?
Each split segment is a standard PDF file. When you split multiple ranges or all pages, the PDFs are packaged inside a ZIP archive for easy download.
How do I split a PDF on a Mac?
Open AlteredIdea PDF Splitter in Safari or Chrome on your Mac. Upload your PDF, choose your split mode, and download the result. No software installation needed.
Can I split a password-protected PDF?
Only if you first remove the password. Use our PDF Password tool, then split the unlocked version.
Is there a page limit?
No. You can split PDFs with hundreds of pages. Larger files may take a few extra seconds since your device's CPU does all the processing.
How do I specify non-consecutive pages?
Enter them as comma-separated values or ranges in the page-ranges field, e.g. '1,3,5-7; 10-12'.
Can I reorder pages when splitting?
Ranges are output in the order you specify them, so you can effectively reorder pages by specifying ranges in your desired sequence.
Will splitting reduce the PDF quality?
No. Pages are copied directly without re-encoding, so quality is identical to the original.
