This tool splits one PDF into several smaller PDF files, based on the page ranges you set, useful for breaking a scanned book into chapters, separating a bundle of invoices that got merged into one file, or pulling a single section out of a long report to send on its own.
The split happens locally using pdf-lib: your document is read once in the browser, divided according to the ranges you specify, and each resulting file is packaged for download without any of it passing through a server. That's a real difference from most online split tools, which need you to upload the whole file before they can even start.
Because pages are copied rather than re-rendered, the output files keep their original text, fonts, images, and quality exactly intact. There's no limit on how many pieces you can split a document into, though splitting a very large file into many separate downloads at once is naturally a bit slower than a single quick operation.
A common case is a scanned batch of separate invoices or forms that got saved as one long PDF by a scanner's default settings, splitting by range turns that back into individual files matching the original documents. It's also useful for breaking a long report into per-chapter files for easier sharing, or pulling out just the pages relevant to one recipient from a document that covers several topics, without needing a full PDF editor installed.
Because you set the exact ranges yourself, splitting works whether you need two roughly equal halves or a dozen small, unevenly sized pieces matching the document's real structure.
How to Split PDF
- Upload the PDF you want to split.
- Set the page ranges for each resulting file (for example, 1-5, 6-10).
- Preview the split to confirm the page ranges are correct.
- Tap "Split PDF" and download the resulting files.
Frequently asked questions
Can I split by custom page ranges, not just even chunks?
Yes, you set exactly which pages go into each output file.
Is my file uploaded anywhere to split it?
No. Splitting happens entirely in your browser using pdf-lib, so the file never leaves your device.
Does splitting reduce the quality of the pages?
No, pages are copied exactly as they are in the source file, nothing is recompressed or re-rendered.
Is there a page count limit?
No artificial limit, it handles documents from a couple of pages up to several hundred, bounded only by your device's memory.
Do I need to sign up to use it?
No signup and no watermark on the output, it's free to use directly.
