About Split PDF
Split PDF is a free, browser-based tool that divides a PDF document into separate files. Choose from four split modes: extract every page as individual PDFs, specify custom page ranges, split into chunks of N pages, or visually select specific pages to extract. The entire process runs locally using the pdf-lib library — your documents never leave your device.

Frequently Asked Questions
What split modes are available?
Three modes: (1) Single Pages — creates one PDF per page, (2) Custom Range — specify exact pages like "1-3, 5, 7-10", (3) Every N Pages — splits into equal chunks of N pages each.
Can I extract specific pages from a PDF?
Yes. Use the Custom Range mode and enter the page numbers you need. For example, "1, 3, 5" extracts pages 1, 3, and 5 as separate files, while "1-5" extracts pages 1 through 5 as a single file.
Does splitting preserve the original quality?
Yes. The split tool copies pages directly from the source PDF without any re-rendering or compression. Text, images, fonts, and formatting are preserved exactly as in the original.
Are my files uploaded to any server?
No. All processing runs locally in your browser using pdf-lib. Your PDF never leaves your device.
Troubleshooting & Technical Tips
Common errors developers encounter and how to resolve them.
Invalid page range error
Ensure your page range uses the correct format: individual pages separated by commas (1, 3, 5), ranges with hyphens (1-5), or combinations (1-3, 5, 7-10). Page numbers must be between 1 and the total page count.
