How to Split a PDF Online Free
Splitting a PDF is one of the most common document tasks — students separating textbook chapters, accountants sending individual invoices, lawyers splitting discovery documents, HR teams distributing policies one at a time, real-estate agents sending property pages to different buyers, and many more. Most online PDF splitters require uploading your file to a remote server, exposing sensitive documents to privacy risks, network delays, and file size limits. Our free PDF splitter runs 100% in your browser: open the page, drop your PDF, get your split files. Your documents never leave your device.\\n\\nThe tool supports three flexible split modes. "Every N pages" splits the document into equal chunks (e.g. every 5 pages produces separate 5-page PDFs). "By page ranges" lets you define custom groups like "1-3, 5-7" — useful when chapters or sections are at irregular intervals. "Extract pages" pulls out specific pages (e.g. "1, 3, 5-7") into individual one-page-or-more PDFs, which is perfect for sharing select pages without distributing the entire document. All three modes can handle any size PDF limited only by your device's available memory.

Frequently Asked Questions
How do I split a PDF into separate files?
To split a PDF into separate files, upload your PDF using the drop zone, choose a split mode ("Every N pages", "By page ranges", or "Extract pages"), configure the split (chunk size or page list), and click "Split PDF". The tool processes the file in your browser and gives you one or more downloadable PDFs. Each file contains the pages you specified, in the order they appeared in the original.
Can I split a PDF into individual pages?
Yes! Select the "Every N pages" mode and set the chunk size to 1. With 1 page per chunk, every page in the PDF becomes its own separate file. If your PDF has 20 pages, you'll get 20 output files named "yourfile_part-1_pages-1-1.pdf", "yourfile_part-2_pages-2-2.pdf", and so on. This is the most common way to extract individual pages from a PDF.
How do I extract specific pages from a PDF?
Use the "Extract pages" mode and type the page numbers you want, separated by commas. For example, to extract pages 1, 3, and 5-7 from a 10-page document, type "1, 3, 5-7". Each page (or range) becomes its own output file. This is useful when you want to share only specific pages without distributing the entire PDF.
Is it safe to split sensitive PDFs?
Absolutely. All processing happens client-side using pdf-lib loaded directly into your browser. Your PDF never leaves your device — no upload, no server processing, no cloud storage, and no third-party access. This makes the tool safe for splitting confidential legal documents, financial reports, medical records, or any other sensitive PDFs that you wouldn't want transmitted over the internet.
What's the maximum PDF size I can split?
There is no artificial file size limit — the tool processes your PDF entirely in your browser using pdf-lib. The practical limit is your device's available memory (RAM), since the tool loads the full PDF into memory for processing. Most modern devices can handle PDFs of 100+ MB without issue. Very large PDFs (500 MB+) may take a few seconds longer but are still well within range.
Will the output PDFs have watermarks?
No. UtilDaily's PDF Splitter adds no watermarks, no page count stamps, no footer text, and no metadata changes to your output files. The split PDFs are clean, exact copies of the pages you specified from the original document, preserving all fonts, images, vector content, and formatting.
Can I split a PDF that's password-protected?
You can split a PDF only if you know the password. The tool does not crack or bypass PDF passwords — you'll need to remove the password first using a separate tool (or supply the password in the file's metadata). Once the PDF is unlocked, the splitter can process it normally.
Does splitting a PDF reduce quality?
No. PDF splitting is a lossless operation — the tool copies pages from the original PDF into new PDF files without re-encoding or rasterizing any content. Fonts, images (including vector graphics), and formatting are preserved exactly as they appear in the original. The output PDFs are byte-for-byte identical to the corresponding pages in the source document.
