Split PDF
Extract pages from your PDF into separate files.
About Split PDF
The PDF Split tool gives users the ability to divide a multi-page PDF document into individual pages or specific page ranges without needing dedicated desktop software. Operating completely client-side via modern JavaScript and WebAssembly, the tool parses the PDF file structure locally to extract the requested pages. It creates entirely new, valid PDF files for each split segment while preserving all original text layers, embedded fonts, and high-resolution images. This approach guarantees complete data privacy since your documents are never transmitted to a cloud server. Whether you need to extract a single signature page from a massive contract, or break down a large presentation into bite-sized chapters, this lightweight utility performs the task instantly.
Common Practical Use Cases
Extracting a single signed page from a lengthy legal contract
Breaking down a massive textbook PDF into individual chapters for easier reading
Isolating a specific chart or diagram from an annual report
