pages / Split

Split

Split a PDF by ranges or every N pages.

Add at least one PDF in the file tray to begin.

Methodology & Technical Transparency

Libraries used

  • pdf-lib — Core PDF construction and editing logic
  • pdf.js — PDF rendering and page rasterisation

Memory strategy

After each operation, URL.revokeObjectURL() is called immediately. All pdf.js document handles are destroyed via pdfDoc.destroy(). Workers are terminated on completion or component unmount.

We do not guarantee the permanent storage of files (as we don't store them). Processing of password-protected files is not supported locally.

Key Features

  • Flexible page ranges

    Specify exact ranges like 1-3, 5, 7-9 — each range becomes a separate output PDF.

  • Uniform splits

    Use 'Every N pages' mode to divide a long document into equal-sized sections automatically.

  • Multi-part ZIP

    When splitting into more than one part, all output files are packaged into a single ZIP for easy download.

Common Use Cases

Perfect for extracting specific chapters from a report, separating invoice pages from a multi-client statement, or distributing only relevant sections to each recipient.

Frequently Asked Questions

How do I specify page ranges?
Enter comma-separated ranges using dashes for spans, for example: 1-3, 5, 8-10. The tool validates the input and highlights errors.
Does splitting reduce PDF quality?
No. The output pages are identical to the originals — no re-rendering or quality loss occurs.
Can I split a PDF into one page per file?
Yes. Set 'Every N pages' to 1 to produce one PDF per page.
