# Split PDF for researchers

_Updated July 2026 · Arthize · https://arthize.com/for/researchers/split-pdf_

Arthize lets researchers and academics split a PDF in a private workspace — free, with no watermark. Splitting a PDF breaks one document into the pieces you need — by page range, by fixed interval, or one file per page — with no quality loss.

## Why researchers split a PDF

A researcher merges a paper with its appendices, extracts a results table into Excel for re-analysis, and compresses the figure-heavy submission under a journal's upload limit — privately.

**Built for papers.** Whether it's papers, datasets, appendices, Arthize's split pdf keeps the work inside your private workspace. Unpublished work and grant applications are confidential; a private workspace keeps them out of public tools.

## What matters when you split a PDF

Splitting is lossless because each output keeps the original page objects.

You can extract just a few pages into a new file while leaving the original untouched.

One-file-per-page mode bursts a document into individual pages in a single pass.

## How to split a PDF

1. **Open the split tool** — Sign in and open the Split tool in your workspace.
2. **Add your PDF** — Upload the document you want to divide; it is processed privately.
3. **Choose how to split** — Pick page ranges (1-3, 4-8), a fixed interval (every N pages), or one file per page.
4. **Download the pieces** — Split and download; each output keeps its original pages unchanged.
