Split PDF — Divide by Page Ranges in Your Browser
ImageSplit PDF is a browser-based PDF tool that creates a separate PDF file for each page range you specify in a single source PDF.
What is it
Split PDF is used to break a long document into chapter files or to carve out a section for submission. Enter comma-separated ranges such as "1-3, 4-6" and each range becomes one output file; a single page is written as "5". The source file is never modified — each output copies the pages of its range as-is. Files up to 50MB are supported, encrypted PDFs are not, and all processing runs in the browser.

- 1Choose the PDF file to split.
- 2Enter comma-separated page ranges, e.g. 1-3, 4-6.

FAQ
Is my PDF uploaded to a server?
No. File selection, splitting, and download creation all run in your browser; the file never leaves your device.
How do I write page ranges?
Each comma-separated range becomes one file. "1-3" means pages 1 to 3, and "5" means page 5 alone. For example, "1-2, 5, 7-9" produces 3 files.
Is the original PDF changed?
No. The source file stays untouched; each range is copied into a new file.
Can I split password-protected PDFs?
No. Encrypted PDFs are not supported. Remove the password first, then split the unlocked file.
