How to Split a PDF Into Separate Pages or Sections

Splitting a PDF is the mirror operation of merging — instead of combining documents, you're separating them. The right splitting method depends on what you're trying to achieve: extracting every page individually, dividing a document at a specific page, or pulling out a non-contiguous selection of pages. This guide covers all scenarios with a method for every platform.

When and Why to Split a PDF

Common use cases where splitting is the right solution:

• Sharing selective content: Sending only pages 5–12 from a confidential 60-page report without exposing the rest
• Fixing scanner output: Scanners create one PDF per document stack — splitting into individual pages lets you reorganise or re-file scanned content
• Chapter extraction: Pulling individual chapters from an ebook or technical manual for reference or distribution
• Size management: Breaking a 200-page document into sections that fit within email attachment limits
• Page-level archiving: Splitting a batch-scanned set of receipts into individual per-receipt PDFs for expense management

Method 1: Browser Split Tool — Free, Private

Folium's Split PDF tool offers two modes: extract every page as its own PDF (bundled in a ZIP), or split the document at a specific page number into two parts. Both modes run entirely in your browser with no file upload.

Extract All Pages Individually

1. Open foliumio.netlify.app/split-pdf.html and upload your PDF.
2. Select Extract all pages individually from the Split Mode dropdown.
3. Click Split PDF. Each page becomes a separate PDF file, named page_1.pdf, page_2.pdf, etc., all packaged into a single ZIP download.

Split at a Specific Page

1. Upload your PDF and select Split at specific page.
2. Enter the page number where the split should occur. Entering 10 creates Part 1 (pages 1–10) and Part 2 (pages 11 to end).
3. Click Split PDF. Two PDFs download in a ZIP file.

Method 2: Extract Specific Pages

Folium's Extract Pages tool is more flexible than the basic split — it lets you specify any combination of individual pages and ranges, and the output contains only those pages in the order you specified.

Input examples:

• 5 — extracts only page 5
• 1,3,7 — extracts pages 1, 3, and 7 (non-contiguous)
• 10-20 — extracts pages 10 through 20 inclusive
• 1,5-8,15 — extracts page 1, pages 5–8, and page 15
• 5,3,1 — extracts pages 5, 3, and 1 in that order (reordering as you extract)

This is the tool to use when creating a "summary" document from a long report — pull the executive summary, key charts, and conclusion pages into a standalone document without anything else.

Method 3: Adobe Acrobat

Acrobat Pro offers the most visual split experience. You see page thumbnails for the entire document and can set split points by clicking rather than typing page numbers — helpful for long documents where you're navigating by visual content rather than knowing exact page numbers.

1. Open the PDF in Acrobat Pro.
2. Go to Tools → Organise Pages. This opens the page thumbnail view.
3. Click Split in the toolbar above the thumbnails.
4. Choose split criteria: Number of pages (split every N pages), File size (create parts under a certain MB), or Top-level bookmarks (split at each chapter marker).
5. Click Output Options to set the folder and filename template, then Split to process.

The "Top-level bookmarks" split mode is particularly powerful for technical documentation or ebooks — it automatically splits at every chapter without needing to know page numbers.

Method 4: macOS Preview

Preview can extract individual pages to new files using drag-and-drop from the thumbnail sidebar.

1. Open your PDF in Preview with the sidebar showing (View → Thumbnails).
2. Select the page thumbnail(s) you want to extract. Hold Shift to select a range, or Command to select non-contiguous pages.
3. Drag the selected thumbnail(s) from the Preview window to your Desktop or a Finder folder.
4. Preview creates a new PDF file containing only the dragged pages, named "Untitled" by default. Rename it appropriately.

Method 5: Command Line with Ghostscript

For batch splitting of many files, Ghostscript is the most powerful free option. It's available on Windows, macOS, and Linux.

Extract pages 5–10 from a PDF:

Split every page into its own file using a shell loop:

Ghostscript preserves text layers, vector graphics, and embedded fonts perfectly through the split operation.

Handling Large PDFs (100MB+)

Browser-based tools process files in your device's RAM. For files over 100MB:

• Close all other browser tabs and applications to maximise available RAM before processing
• Chrome and Edge handle larger files better than Firefox or Safari for this operation due to their JavaScript engine memory management
• For files over 200MB: use PDFsam, macOS Preview, or Ghostscript (desktop tools have no browser RAM constraints)
• Consider a staged approach: split a 500-page document into 5 parts of 100 pages first, then process each part
