How to use Split PDF
- Select or drop the PDF you want to split.
- Choose a mode: custom ranges (e.g. 1-3, 4-8), every page separately, or extract selected pages into one file.
- Click “Split PDF”. One file downloads as a PDF; several files download together as a ZIP.
Three ways to split
Custom ranges creates one PDF per range — type 1-3, 4-10, 11- to get three files (a range like 11- means “to the end”). Every page creates a separate PDF for each page, handy for scanned batches of single-page forms. Extract pages collects the pages you list, such as 2, 5, 9-12, into one new PDF.
Lossless and private
Splitting copies the original page objects into new documents, so nothing is re-rendered or compressed. And because bopdf runs in your browser, you can safely split confidential documents such as payslips or contracts — the file is never uploaded.
🔒 Your files never leave your device
bopdf processes your documents locally with JavaScript (pdf-lib and Mozilla pdf.js) inside your browser tab. Your PDF is never uploaded, stored or seen by us — you can even disconnect from the internet after the page loads and the tool keeps working. When you close the tab, everything is gone.
Frequently asked questions
How do I split a PDF into individual pages?
Choose “Split every page into a separate PDF” and click Split PDF. You get one PDF per page, bundled in a ZIP.
How do I split a PDF in two?
Use custom ranges, for example 1-10, 11- (the second range runs to the last page).
How do I write page ranges?
Separate ranges with commas: 1-3, 5, 8-10. Use “8-” to mean page 8 to the end.
Why did I get a ZIP file?
When a split produces more than one PDF, they are bundled into a single ZIP so you can download them with one click. Every computer and phone can open ZIP files.
Can I remove pages instead?
Yes — use Organize PDF to delete pages visually, or extract the pages you want to keep here.
Is there a page limit?
No fixed limit. Documents with hundreds of pages split in seconds on a typical computer.
Are my files uploaded to a server?
No. Everything happens in your browser on your own device. Files are never sent over the internet, which makes bopdf suitable for confidential documents.
Is there a file size limit?
There is no fixed limit, but very large files (hundreds of MB) depend on your device memory. On phones, files up to about 100 MB usually work well.
