Split PDF Online
Extract specific pages or page ranges from any PDF — free, private, and instant. No files are uploaded to any server.
What Is a PDF Splitter?
A PDF splitter lets you extract specific pages from a PDF document and save them as a new, smaller PDF. Instead of sharing a 50-page report when your recipient only needs pages 3–10, you can split the document and send just the relevant section. This saves bandwidth, reduces file size, and keeps irrelevant content private.
TweakFiles splits PDFs entirely in your browser using client-side JavaScript (pdf-lib). Your file is never uploaded to any server, making it faster and more private than server-based tools like iLovePDF, Smallpdf, or Adobe Acrobat online. Your sensitive contracts, tax forms, and personal documents stay on your device at all times.
When Should You Split a PDF?
PDF splitting is essential when you need to extract specific sections from large documents. Whether you’re pulling a single chapter from an ebook, extracting an invoice from a bank statement, or separating scanned pages that were combined into one file, splitting gives you precise control over what pages end up in your final document.
It’s also useful for meeting email attachment limits. A 30 MB PDF can be split into smaller sections that fit within the 25 MB limit of Gmail, Outlook, and Yahoo Mail. Or you can extract just the pages you need, which is often much smaller than the full document.
Common Use Cases
- Extract specific chapters or sections from ebooks and reports
- Pull individual invoices or statements from combined financial documents
- Separate scanned pages that were accidentally combined
- Create smaller PDFs for email attachments (Gmail 25 MB limit)
- Extract forms from multi-page government or legal documents
- Share only relevant pages from lengthy contracts or proposals
- Create handout PDFs from presentation slide exports
How TweakFiles Split Works
TweakFiles uses pdf-lib to copy selected pages from your original PDF into a new document. This is a lossless operation — text, images, fonts, annotations, and form fields are preserved exactly as they appear in the original. The new PDF contains only the pages you selected, with no quality loss and no re-rendering. Page thumbnails are generated using PDF.js for a visual preview before you split.
How to Split a PDF in 3 Steps
Upload Your PDF
Drag and drop your PDF file into the drop zone above, or click to browse your files. TweakFiles accepts PDFs of any size — the processing happens entirely on your device using your browser’s built-in capabilities. Your file is never uploaded to any server, making it safe for sensitive documents like tax returns, contracts, and medical records.
Select Pages to Extract
Click on page thumbnails to select or deselect individual pages. You can also type page ranges in the input field using formats like “1-3, 5, 7-9”. Selected pages are highlighted in blue. Use “Select All” or “Deselect All” buttons for quick bulk selection. The page count updates in real-time as you make your selection.
Download Your Split PDF
Click the download button to save a new PDF containing only your selected pages. The filename automatically gets “-split” appended so you can easily distinguish it from the original. Your original PDF is never modified or deleted — TweakFiles creates a new, smaller document while leaving the source file untouched.
