100% client-side — your PDF never leaves your device

Split PDFs,
without the upload.

Pull out the pages you need or break a PDF into separate files — right in your browser. Click, or type a range.

How it works

  1. 1

    Drop your PDF

    Add a PDF file. Every page is rendered locally with pdf.js as a clickable thumbnail — no upload.

  2. 2

    Pick your pages

    Click the pages you want, or type a range like 1-3, 5, 8-10. Leave it empty to use every page.

  3. 3

    Extract or split

    Get one PDF of the selected pages, or split each page into its own file (zipped) — assembled with pdf-lib in your browser.

Frequently asked questions

Is my PDF uploaded to a server?+

No. The file is read and split entirely in your browser. Your PDF never leaves your device.

What's the difference between Extract and Split?+

Extract combines the pages you selected into a single new PDF. Split makes one separate PDF per selected page and hands them back as a .zip (a single page downloads as one PDF).

How do I select pages?+

Click the page thumbnails to toggle them, or type a range like 1-3, 5, 8-10 in the Pages box. If you select nothing, all pages are used.

Is there a limit on PDF size or page count?+

No hard limit beyond your device's available memory. Everything runs locally.

Is it free?+

Yes — free, no signup, no watermarks.
