How to Use Split PDF

01

Upload PDF

Select the PDF file you wish to split.

02

Specify Ranges

Enter the page numbers or ranges to extract.

03

Split & Save

Process the file and save individual PDF parts.

Key Capabilities

Split by page ranges (e.g. 1-3, 5, 8-10)
Burst entire document into single-page PDFs
Instant browser-side extraction
No data sent over the internet

Local Execution

The document structure is parsed locally in the browser. You select page ranges or individual pages, and our engine creates new standalone PDF binaries instantly.

Helpful Tips
  • •Use commas for multiple ranges like 1-5, 8, 11-14.
  • •Preview thumbnails to verify exact page numbers.
  • •Specifying page numbers higher than total pages will produce an error notice.

Page Tree Decomposition & Range Extraction Architecture

Custom Range Tokenization

Our range parser evaluates complex expressions (e.g. "1-3, 5, 8-10") directly in memory. It verifies page boundaries against the document catalog before constructing output sub-documents.

Independent Resource Dictionary Cloning

When pages are extracted, associated font descriptors, images, and shading dictionaries are isolated and copied into the new container, ensuring extracted pages remain visually self-contained.

Burst vs Range Splitting

In burst mode, each page is emitted as an individual standalone PDF file and bundled into a standard in-browser ZIP archive without sending any data over external networks.

Technical Notes
  • •Page numbers are 1-based matching standard document conventions.
  • •Extracted sub-documents preserve original vector typography and embedded images at 100% fidelity.
  • •Files requiring passwords must be authenticated prior to extraction.
