The most common mobile split scenario: you receive a long document and need to forward only a portion of it. A property manager sends a 40-page lease and you need only the signature pages. A recruiter sends a benefits package and you need to share just the health plan summary.
Rather than forwarding the entire document with a "see page 23" note, extract the relevant pages and send a clean, focused file. ModernPDF runs in Safari without any app installation, processes the split on your iPhone, and lets you share the result immediately.
Extract signature pages from a 40-page lease for quick tenant signing on the go.
Pull the benefits summary from a full employee handbook to send to a candidate.
Extract a specific pricing page from a product catalog before a client meeting.
Pull a specific problem set or chapter from a course PDF before your next class.
Here is the step-by-step process for splitting PDFs on your iPhone:
1. Open Safari and navigate to modernpdf.app/tools/split-pdf. Add it to your Home Screen for future quick access.
2. Tap the upload area. The iOS file picker opens — choose your PDF from Files, iCloud Drive, Mail attachments, or any connected cloud storage.
3. The tool loads your PDF and displays page thumbnails. Scroll through to find the pages you need.
4. Tap individual page thumbnails to select them. Selected pages are highlighted with a blue border. Tap again to deselect.
5. For range selection, enter the page numbers in the range input field (e.g., "5-12").
6. Tap extract/split. The new PDF is generated on your iPhone in seconds.
7. Save to Files, share via AirDrop to your Mac, attach to an email, or send via Messages. The original document remains untouched in its original location.
If you've searched for how to split a PDF on iPhone, you've probably found apps that want you to download software or upload your files to a remote server. ModernPDF takes a different approach: it runs entirely in Safari using WebAssembly, so your iPhone handles the split locally — no app install, no cloud upload.
Whether you need to split PDF on your iPhone before a meeting, extract a few pages from a contract on the go, or quickly separate a large document into smaller files, this tool works on any iOS device running Safari. It's the fastest way to handle PDF splitting on iOS without compromising your privacy.
You can also split PDFs on iPad using the exact same workflow. The tool adapts to your screen size and works identically across all Apple devices — iPhone, iPad, and even Mac via Safari.
