Split PDF
When this tool is a good fit
Split PDF helps when you need one or more PDFs, often downloaded as separate files or a ZIP from one PDF plus page ranges or split instructions. It is most useful for extracting pages, removing extras, creating chapter files, and preparing smaller PDFs from a large document. The notes below focus on the settings that matter, the checks worth doing before you export, and the limits that tend to cause mistakes.
- Takes one PDF plus page ranges or split instructions.
- Lets you adjust page ranges, split mode, output grouping, and whether pages should be preserved in original order.
- Calls out what to review: first and last page numbers, missing blank pages, off-by-one range errors, and filenames.
- Produces one or more PDFs, often downloaded as separate files or a ZIP.
- Fits common jobs such as extracting pages, removing extras, creating chapter files, and preparing smaller PDFs from a large document.

How to use Split PDF
- Prepare one PDF plus page ranges or split instructions.
- Set page ranges, split mode, output grouping, and whether pages should be preserved in original order before running the tool.
- Generate or process the result, then review first and last page numbers, missing blank pages, off-by-one range errors, and filenames.
- Copy, export, or download one or more PDFs, often downloaded as separate files or a ZIP.
- Run a second pass if the destination system, document, or workflow has stricter requirements.
What to know before you use it
- The selected PDF is loaded locally with pdf-lib.
- Split settings define groups of page indexes that are copied into new PDF documents.
- Multiple output PDFs are packaged into a ZIP archive in the browser.
- PDF page numbers in viewers may differ from printed page labels, so count actual document pages before entering ranges.
- Splitting preserves source page content but cannot repair a damaged or encrypted input PDF.
Checks and edge cases
- Preview the page count before splitting a scanned packet or statement.
- Use Merge PDF after splitting if you need to reassemble only selected pages.
How your data is handled
PDF splitting runs locally in your browser. Toolumina does not upload, read, or store the selected PDF.
FAQ
Can I extract a page range?
Yes. Use ranges such as 1-3,5 to select pages.
Can I split every page separately?
Yes. Every page mode creates one PDF per page.
Why is the output a ZIP?
Splitting often creates multiple PDFs, so the browser packages them into one ZIP download.
