Split PDF Files

When to Split a PDF

PDF splitting solves a surprisingly common problem: you have one large document but need to share, file, or work with only part of it. Common scenarios include extracting a single invoice from a 50-page billing statement, pulling your resume out of a combined job application package, separating chapters from a long report for individual review, or breaking a large scanned document into smaller files that fit email attachment size limits.

For legal and compliance workflows, splitting is essential: contracts often need to be circulated one section at a time for review, and court filings frequently require documents to be submitted as separate exhibits rather than a single combined file. Splitting PDFs also helps with version control — when different sections are updated by different people, keeping them as separate files prevents the entire document from needing to be re-reviewed when only one section changes.

Page Ranges and File Size

Splitting a PDF by page range means specifying exactly which pages to extract into a new file. For example: extract pages 1–5 for the executive summary, pages 6–18 for the technical appendix, and pages 19–24 for the financial data. Each extracted range becomes a fully functional standalone PDF with its own table of contents, bookmarks, and metadata intact where possible.

File size after splitting is roughly proportional to the number of pages extracted. A 20MB, 100-page PDF split into four 25-page sections will produce files of approximately 5MB each. The exception is PDFs with high-resolution embedded images, where a single image-heavy page might account for a disproportionate share of the total file size. All processing happens in your browser — no file size limits from server upload restrictions.
