Technical Architecture & Privacy
Split a large PDF document into smaller sections by specifying page ranges such as 1-3, 5, 8-10, or extract each page into a separate file inside a ZIP archive.
Unlike conventional PDF websites that send your personal tax forms, legal agreements, and corporate contracts to third-party cloud infrastructure, PDFolio operates under a Zero-Server Architecture. Your documents are decoded into pure memory buffers (Uint8Array) inside your browser's dedicated JavaScript runtime or Web Worker. When you click download, the newly assembled PDF is produced directly from memory into your Downloads folder.
Frequently Asked Questions
How do I specify multiple ranges?
Separate ranges with commas, for example "1-5, 8, 11-14".
Does splitting reduce the quality of the document?
Not at all. PDF pages, vector graphics, fonts, and images are copied losslessly.
