How to Split a PDF on iPhone: Extract Pages and Divide Documents for Free

Sometimes you need just a few pages from a large PDF. Maybe a 50-page report where you only need pages 12 through 18, or a contract where your signature page needs to go in a separate file. Splitting PDFs on your iPhone is straightforward once you know the right approach. Here are the best free methods.

Why Split PDFs on Your Phone?

Splitting PDFs on your iPhone is useful when you need to:

• Share only relevant pages — send just the pages someone needs, not the entire document
• Reduce file size — extract a few pages instead of sending a massive file
• Submit specific sections — tax forms, visa applications, and school submissions often require individual pages
• Organize documents — break one large PDF into themed sections
• Privacy — separate pages containing sensitive information from the rest

Method 1: Using the Files App and Print Trick

A clever built-in method that requires no additional apps:

1. Open the Files app and locate your PDF.
2. Tap the PDF to open it in the quick-look preview.
3. Tap the Share button in the top-right corner.
4. Choose Print from the share sheet.
5. In the print preview, use the range selector to choose which pages you want (for example, pages 3-7).
6. Pinch outward on the print preview to expand it into a full PDF.
7. Tap Share again and choose Save to Files.
8. Name the new file and save it.

This trick works on any iPhone running iOS 15 or later. It extracts only the pages you selected in the print range, creating a clean new PDF with just those pages.

Method 2: Using Markup to Delete Pages

Another built-in approach using the markup tools:

1. Open the PDF in Files.
2. Tap the Markup button (pen icon at the top).
3. Tap the page thumbnail view icon at the left edge of the toolbar.
4. You see thumbnail previews of all pages.
5. Tap Select at the top-right.
6. Tap the pages you want to keep (or the ones to delete).
7. Tap Delete to remove unwanted pages.
8. Tap Done to save the modified PDF.

Note that this modifies the original file. If you want to keep the original intact, duplicate the PDF first by long-pressing it and choosing Duplicate, then work on the copy.

Method 3: PDF Expert (Best App Option)

PDF Expert by Readdle gives you the most control over splitting:

1. Install PDF Expert from the App Store.
2. Open your PDF in the app.
3. Tap the thumbnails icon to see all pages.
4. Tap Select and choose the pages you want to extract.
5. Tap Extract to create a new PDF with just those pages.
6. Or tap Split to divide the document at the selected point.

PDF Expert lets you extract non-consecutive pages — pull pages 1, 5, and 12 into one file. The built-in methods only work with continuous page ranges.

Method 4: Adobe Acrobat Reader

The free version of Adobe Acrobat for iOS includes page extraction:

1. Install Adobe Acrobat Reader from the App Store.
2. Open your PDF in the app.
3. Tap the Organize Pages tool.
4. See all pages as thumbnails.
5. Select pages and choose Extract or Delete.
6. Save the result as a new file.

Adobe Acrobat also lets you rotate, reorder, and crop pages in the same interface. Good for quick edits along with splitting.

Method 5: Online Splitters via Safari

Browser-based tools work on iPhone too:

1. Open Safari and visit a PDF splitting site like iLovePDF, Smallpdf, or Sejda.
2. Upload your PDF from Files or Photos.
3. Select which pages to extract or where to split.
4. Download the resulting file(s).

As with all online tools, avoid uploading sensitive documents. Use the on-device methods for anything containing personal or financial information.

Splitting Strategies

How you split depends on what you need:

• Extract a single page — use the Print trick with a one-page range
• Extract a range — same method, wider range
• Split into equal parts — online tools like Sejda have a "split every N pages" option
• Split by bookmarks — desktop tools handle this better; on iPhone, extract manually by bookmark section
• Extract non-consecutive pages — PDF Expert is the only reliable free option on iPhone

Frequently Asked Questions

Does splitting a PDF reduce quality?

No. Splitting is lossless — the extracted pages maintain the exact same quality as the original. Text, images, and vector graphics are preserved perfectly.

Can I split a password-protected PDF?

You need to enter the password to unlock it first. Once open, all splitting methods work as normal. Some apps like PDF Expert remember the unlock for the session.

What is the maximum PDF size I can split on iPhone?

The Files app and built-in tools handle PDFs up to about 500MB. For larger files, use PDF Expert or Adobe Acrobat, which manage memory more efficiently. Online tools typically have a 100MB free-tier limit.
