PDF Splitter

Split a 4-page PDF into 4 file(s).

How it works

• Read the selected PDF's page tree with the local rewrite engine.
• Resolve the every split into output files with their page selections.
• Copy the requested pages into a fresh PDF per output and offer each for download.

• Nothing is uploaded; the rewrite runs in your browser.

Methodology

1. Read the document's page tree and validate the requested split against the real page count.
2. Every-page produces one single-page file per page; fixed produces sequential parts; ranges produces one file per range.
3. Copy the selected pages into a fresh PDF with the object-graph rewrite engine so every output reopens as a valid PDF.
4. Reject out-of-range, reversed or empty ranges with a named finding and emit no partial file.

Usage

1. Choose or drop a PDF.
2. Pick a split mode: every page, fixed-size parts, or explicit ranges.
3. Run the split and download each resulting PDF.

Examples

These are examples, not current values: they use fixed inputs, while the interactive tool computes live results in your browser.

Split a 4-page PDF into single pages

{
  "pageCount": 4,
  "mode": "every",
  "baseName": "report"
}

Split a 4-page PDF into 1-2 and 4

{
  "pageCount": 4,
  "mode": "ranges",
  "ranges": "1-2, 4",
  "baseName": "report"
}

Limitations

Local, valid outputs

Splitting copies the requested pages into a brand-new PDF document, so each result has a correct page tree, cross-reference table and trailer and reopens in any reader.

The tool never uploads your file and never leaves a partial output behind when a range is invalid.
