How to Split a PDF

1

Upload Your PDF

Click the upload area above, or drag and drop your PDF file onto the page. Once uploaded, the tool displays the total page count so you know what you're working with. Your file stays on your computer — nothing is uploaded.

2

Enter Page Ranges

Type the pages you want to extract, separated by commas. You can use individual numbers and ranges — for example, "1-3, 5, 8-10" extracts pages 1 through 3, page 5, and pages 8 through 10. Page numbers match what you see in your PDF viewer, starting from 1.

3

Extract and Download

Click "Extract Pages" and the tool copies your selected pages from the original PDF into a new file. This is very fast since it only copies pages without re-rendering. Download the result immediately.

Why Use Online Split

Extracted pages are identical to the original — text, images, layout, and selectable text all stay exactly the same. Unlike compression, splitting copies pages as-is without any quality loss.

No software to install, no usage limits, no watermarks. Open the page, type your page numbers, and you're done.

Free, no sign-up, no uploads — all processing happens right in your browser.

Common Use Cases

Send only what's needed — Got a 50-page report but the recipient only needs pages 3-7? Extract just those pages instead of sending the whole file. Extraction guide

Pull out a chapter — Need one chapter from a textbook or manual? Enter the page range and extract it as a standalone PDF.

Remove cover or blank pages — Scanned PDF has an unwanted cover page or blank pages at the start? Just extract the pages you actually need.

Split exams by section — Teachers can split a test bank into separate sections for different classes. Teacher's PDF guide

Things to Note

  • Original file is never modified — Splitting creates a brand new PDF from copied pages. Your original file stays exactly as it was.
  • Page numbers start at 1 — Page numbering matches what you see in your PDF viewer (Adobe Reader, Preview, etc.).
  • Non-contiguous pages work fine — Something like "1, 3, 5-8, 12" extracts scattered pages and combines them into one new PDF.
  • Still too large after splitting? — Use the Compress tool to reduce the extracted pages to your target size.
