# Split PDF

## What It Does
Splits a single PDF into multiple smaller PDFs. Supports splitting by page ranges, one page per file, or fixed number of chunks.

## When to Use
- Extract specific pages from a large PDF
- Split a document into individual page PDFs
- Divide a PDF into N equal parts

## Split Modes
| Mode | Param | Behaviour |
|------|-------|-----------|
| By pages | `pages: "1-3,5,8-10"` | Each comma group = one output PDF |
| Each page | `mode: "each"` | One PDF per page |
| Fixed chunks | `chunks: 3` | Split into N roughly equal parts |
| Default | (none) | Same as `mode: "each"` |

## Required Inputs
Provide one of:
- `url` — public URL to a PDF
- `file` — base64-encoded PDF
- Multipart upload with `file` field

## Authentication
Send your API key in the `CLIENT-API-KEY` header.

- **Batch Processing** — Split a multi-page scanned document into individual page files
- **Archival** — Break large PDFs into smaller files for easier storage and retrieval
- **Print Shop** — Split documents into sections for different print runs

## Limits
- Max 200 pages per document
- Max 100 output chunks
