How Split PDF Works

ConvertUnlimited utilizes pdf-lib, a modern JavaScript library for PDF manipulation that runs natively in your browser. When you upload a document, our tool parses its internal structure locally. Based on your specified ranges (e.g., "1-3" or "5, 10"), it creates a new PDF container and copies the specific page objects into it.

Because all logic is executed on your device's CPU and RAM, your document contents are processed locally in your browser. This local-first architecture ensures local browser-based processing for sensitive files like medical records, legal contracts, and personal documents.

Why Split PDF Files?

• Extracting Specific Pages: Grab only the summary or the signature page from a long report.
• Separating Large Documents: Break a massive ebook into chapters for easier reading.
• Privacy Protection: Remove unnecessary pages before sharing a document with others.
• Organization: Split a multi-scan PDF into individual one-page documents.

Page Range Examples

Our tool supports flexible syntax for selecting pages:

• Single Pages: Type 5 to extract only page 5.
• Continuous Ranges: Type 1-3 to extract pages 1, 2, and 3.
• Complex Combinations: Type 1-3, 5, 8-10 to extract pages 1, 2, 3, 5, 8, 9, and 10 into one new file.

Frequently Asked Questions

Can I split every page at once?

Yes. Use the "แยกทุกหน้า" button to automatically generate a separate PDF for every single page in your document. These will be bundled into a convenient ZIP archive for download.

Does it work with encrypted PDFs?

Password-protected files cannot be split unless they are decrypted first. Please remove the password using a dedicated utility before using this tool.
