How to Split a PDF into Multiple Files

Splitting a PDF means extracting a subset of pages into a separate document. You might want to pull out a single invoice from a multi-page statement, separate chapters from a report, or divide a large scan into smaller parts for email. CalmPDF lets you do this in your browser — no upload, no account, free.

When would you split a PDF?

Common reasons to split a PDF include:

• Extracting a single invoice from a combined monthly statement.
• Separating chapters from a long report or ebook.
• Dividing a scanned batch into individual documents.
• Removing pages you don't want to share before sending a file.
• Creating handouts from specific pages of a presentation.

How to split a PDF using CalmPDF

Step 1: Open the split tool

Go to calmpdf.com/split-pdf in any browser. The tool works on Mac, Windows, iOS, and Android — no app to install.

Step 2: Drop your PDF

Drag the PDF into the upload area, or click to browse. The file loads in your browser and is never sent to a server.

Step 3: Choose a page range

Enter the pages you want to extract. For example, if you want pages 3 through 7, enter 3 in the "From" field and 7 in the "To" field. To extract a single page, enter the same number in both fields (e.g., 5 to 5).

To split every page into its own file, choose the Every page option. CalmPDF will package all the individual pages into a ZIP download.

Step 4: Download the result

Click Split. For a page range, you get a single PDF. For every-page splits, you get a ZIP containing one PDF per page. Your original file is not modified.

Splitting a PDF on Mac without a tool

Mac users can split PDFs using Preview without any additional software:

1. Open the PDF in Preview.
2. Go to View → Thumbnails.
3. Select the pages you want to keep (hold Shift or Cmd to select multiple pages).
4. Drag the selected pages to the desktop or a Finder window to create a new PDF from those pages.

Splitting a PDF on Windows

Windows doesn't have a built-in PDF splitter. Options include:

• CalmPDF — works in any browser, no install needed.
• Adobe Acrobat Reader — splitting requires the paid Acrobat Pro version.
• PDF24 — free desktop app for Windows with a split feature.

Frequently asked questions

Does splitting a PDF affect quality?

No. Splitting extracts pages without re-encoding them. Images, fonts, and text remain exactly as they were in the original document.

Can I split a PDF into equal parts?

CalmPDF currently splits by page range. To create equal parts from a 20-page PDF, you'd run the split operation multiple times (pages 1–5, 6–10, etc.). The every-page option splits into individual pages automatically.

Can I split password-protected PDFs?

Password-protected PDFs need to be unlocked first. Open the PDF in Preview (Mac) or Adobe Acrobat, remove the password protection, save, then split.

Will bookmarks and links be preserved?

Internal links within the extracted page range are preserved. Links pointing to pages outside the extracted range may break, since those pages no longer exist in the new file.
