Split PDF

Good times to use it

Use Split PDF for extracting pages, removing extras, creating chapter files, and preparing smaller PDFs from a large document. It works well when you want one or more PDFs, often downloaded as separate files or a ZIP and do not need a bigger workflow around it.

• Best fit: extracting pages, removing extras, creating chapter files, and preparing smaller PDFs from a large document.
• You start with one PDF plus page ranges or split instructions.
• The useful choices are page ranges, split mode, output grouping, and whether pages should be preserved in original order.
• Check first and last page numbers, missing blank pages, off-by-one range errors, and filenames.
• You end up with one or more PDFs, often downloaded as separate files or a ZIP.

Use Split PDF like this

1. Start with one PDF plus page ranges or split instructions.
2. Choose page ranges, split mode, output grouping, and whether pages should be preserved in original order.
3. Run the tool once, then review first and last page numbers, missing blank pages, off-by-one range errors, and filenames.
4. Copy, export, or download one or more PDFs, often downloaded as separate files or a ZIP.
5. Open the finished file once before you send or archive it.

What usually goes wrong

• 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.
• Preview the page count before splitting a scanned packet or statement.
• Use Merge PDF after splitting if you need to reassemble only selected pages.

What the page is doing

• 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.

How your data is handled

PDF splitting runs locally in your browser. Toolumina does not upload, read, or store the selected PDF.
