Drop a PDF to split it into separate files — splitting runs locally in your browser and the file is never uploaded.
How it works
- Every page makes one single-page PDF per page. Custom ranges lets you carve out specific chunks (e.g. chapters). Every N pages splits into evenly-sized batches. Split in half divides the document down the middle.
- Each resulting PDF appears as a card below — click any card to download it individually, or use "Download all".
- A short ad plays before your download starts — it helps keep this tool free. Processing itself happens instantly; the ad is just a brief pause before the file downloads.
- All processing happens locally in your browser using pdf-lib — your files are never uploaded anywhere.
Split a PDF into separate files — by page ranges, every N pages, or one file per page — entirely in your browser. Your document is never uploaded, so it stays private.
Frequently asked questions
Is my PDF uploaded to a server?
No. Splitting happens locally in your browser using the PDF engine, so even confidential documents never leave your device.
How can I split the file?
By custom page ranges (for example 1-3 and 7-9), by a fixed chunk size (every N pages), or into one file per page — whichever matches your task.
Is there a file-size or page limit?
There's no fixed server limit because it runs on your device; very large PDFs simply use more of your device's memory, so extremely big files may be slower on low-memory devices.
Will splitting reduce quality?
No — splitting copies the original pages exactly, so text stays selectable and images keep their original resolution.
About splitting a PDF
Splitting takes one PDF and pulls out the pages or ranges you specify, producing a smaller document (or several). It's the counterpart to merging — useful when you only need part of a long file, or need to separate a bundle back into pieces.
The split runs in your browser, so a confidential document never leaves your device.
Common uses
- Extracting a single chapter or section from a long PDF.
- Separating a scanned bundle into individual documents.
- Removing pages you don't want to share.
- Breaking a large file into smaller ones that fit an upload limit.
Use it carefully
Double-check your page ranges before splitting — it's easy to be off by one, since page numbers printed on the page don't always match the PDF's own numbering. Preview which pages you've selected, and keep the original until you've confirmed the split contains exactly what you expected.
Understanding your results
You get a new PDF containing only the pages you chose, in the order they appeared in the original. If you specify several ranges, you can get several files.
Use the visual page picker to click the pages you want rather than typing numbers — the field and the thumbnails stay in sync, so you can see your selection before you split.
How do I choose which pages to keep?
Type page numbers and ranges like 1-3, 7, or click pages directly in the thumbnail picker.
Does splitting reduce quality?
No. The pages are copied exactly as they are in the original.
Are the pages I remove really gone from the new file?
Yes — the output contains only the pages you selected. Your original file is untouched.
Splitting by page ranges
Splitting pulls chosen pages out of a PDF into their own file (or files). You describe what you want with page ranges — for example, pages 1-3, 7, and 10-12 — and the tool produces exactly those pages. It's the reverse of merging: instead of joining documents, you're separating sections.
How page ranges are written
A range like 1-3 means pages one through three inclusive; a single number like 7 means just that page; and you can combine them with commas. The page numbers refer to the document's visible order, starting at one, which is usually what you'd expect.
When splitting is the right tool
Splitting suits pulling one chapter out of a report, separating a single form from a bundle, or breaking a long scan into smaller files that are easier to email. Because you keep only the pages you name, the output is often much smaller than the original.
Why splitting is easier in page-oriented formats
Because PDF has explicit page boundaries, a long document can be divided by ranges without needing to understand paragraphs or chapters.
A range is an inclusive count
Splitting pages 10--15 creates six pages, not five: 15 - 10 + 1 = 6.
