Split a PDF

Split PDF Free Online — Extract Pages Without Uploading

FusionPDF splits PDFs entirely in your browser using pdf-lib, an MIT-licensed open-source library. You can extract a custom page range, separate every page into its own file, or split at fixed intervals — with no file ever leaving your device. For a 200-page confidential report, that distinction matters.

How to Split a PDF

The process has three steps. Drop your PDF into the upload area, or click to select it from your device. Choose your split mode and enter the pages you want — for example, "1-3, 5, 8-10". Click "Process and download" to get the result immediately. For single-page extraction the output is one PDF. For a full page-by-page split the tool packages all pages into a ZIP archive.

Four Ways to Split a PDF

FusionPDF supports four distinct splitting approaches, covering the most common real-world tasks.

• Extract a page range: Enter a range like "2-7" to pull out a consecutive block of pages as one PDF. Useful for extracting a chapter or section.
• Extract specific pages: Enter non-consecutive pages like "1, 4, 9" to build a new PDF from exactly those pages. Useful for isolating signature pages or pulling key exhibits.
• Split all pages: Separate every page into its own individual PDF file. All files are bundled in a ZIP archive for download. Common for processing scanned batches where each page is a separate document.
• Odd/even split: Extract only odd-numbered or even-numbered pages — helpful when a double-sided scan places front and back on alternating pages.

Split vs. Extract vs. Delete Pages — Which to Use?

These three operations are related but serve different purposes. Use Split when you want to divide a document into multiple output files. Use Extract when you want to create a new PDF from a subset of pages, leaving the original intact. Use Delete Pages when you want to keep most of the document but remove specific pages, producing a single cleaned-up output. All three tools are available free on FusionPDF and all run locally in your browser.

Why Split PDFs in the Browser?

When you extract one page from a 200-page confidential report using an upload-based tool, the entire document travels to a third-party server. The tool processes it, and your 200-page file sits on external infrastructure for some period of time before deletion — assuming deletion actually occurs. For legal documents, HR files, financial statements, and medical records, that exposure is not acceptable.

Browser-based splitting removes that risk entirely. The PDF never leaves your machine. pdf-lib reads the file in memory, copies the requested page objects into a new document, and writes the output directly to your device. No network request is made after the page loads.
