Splitting a PDF on iPhone is useful when you need to share just a few pages from a longer document, extract a specific chapter, or reduce a file to a manageable size before sending. iOS doesn't have a built-in split tool, but both the browser and the Files app give you reliable options.
How to Split a PDF on iPhone Using a Browser Tool
Open Safari and go to WukongPDF's Split PDF tool. Tap the upload button and select your PDF from Files or iCloud Drive. The tool shows you all the pages as thumbnails. Choose how you want to split โ by page range, into individual pages, or at specific page breaks โ then tap Split and download the resulting files.
If the split produces multiple files, they're usually delivered as a ZIP archive. In Files on iOS 16 and later, you can tap a ZIP file to extract it directly without a third-party app.
How to Extract Pages Using the Files App
iOS 16 added basic PDF editing directly into the Files app, including the ability to delete and rearrange pages โ which you can use to extract specific pages from a PDF.
First, duplicate the PDF in Files (tap and hold the file, then select Duplicate) so you have a copy to work with. Open the duplicate, tap the page icon in the corner to see all pages, then tap and hold any page to select it. Use the selection mode to delete the pages you don't want. What remains is your extracted section. This is a manual approach โ practical for small documents but tedious for long ones.
Splitting a PDF Into Individual Pages on iPhone
If you need every page as a separate PDF file โ for uploading to a form that accepts one page at a time, or for organizing individual pages into a filing system โ the browser-based Split PDF tool handles this automatically. Select the option to split into individual pages, upload your document, and download the ZIP file containing one PDF per page.
This is much faster than manually duplicating the PDF and deleting pages one by one for each file you need.
Using an App to Split PDFs on iPhone
Several App Store apps handle PDF splitting with a better interface than a mobile browser. PDF Expert, Readdle's Documents, and Scanner Pro all include split functionality. These apps store files locally and don't require an internet connection for processing, which is useful when you need to work offline.
PDF Expert is the most polished option for frequent PDF work on iPhone โ it lets you visually select page ranges, preview the output before splitting, and save directly to iCloud Drive or share via the standard iOS share sheet.
Sharing Split PDF Pages From iPhone
After splitting, each extracted section is a standard PDF that can be shared like any other file on iPhone. Tap and hold the file in Files, select Share, and choose your method โ Mail, Messages, AirDrop, WhatsApp, or uploading directly to a cloud service.
If the extracted pages are still larger than you need โ for instance, if you extracted an image-heavy chapter โ running the result through a compression tool before sharing keeps the file size manageable. WukongPDF's compression tool works in Safari on iPhone the same way the Split PDF tool does.
