PDF Splitter

Read full description

PDF Splitter splits PDF files the way you need and extracts only the pages you want. Your original PDF stays unchanged, and you can share the results as separate PDFs or one ZIP file. Everything runs on your device, and your PDFs are never uploaded to a server. โ–  5 ways to split a PDF โ€ข Every page: separate every page into its own PDF โ€ข Every N pages: split a PDF every 2, 3 or more pages โ€ข Page ranges: one PDF for each range, such as 1-4, 5-8 โ€ข Chosen pages into one file: extract pages such as 1, 3, 7-9 and save them as one PDF โ€ข Odd or even pages: odd pages only, even pages only, or both as two files โ–  Pick pages on previews Tap page thumbnails to choose pages, and the ranges are filled in for you. Quickly extract the pages you need from scans and reports. โ–  File naming Set the start of the file names and number them by page (pages-001-004) or in order (part-01). An example name is shown before you split. โ–  Share and export Share split PDFs one by one or export them all as a ZIP file. You can also open a PDF from another app and split it right away. โ–  Password-protected PDFs Enter the password to open a locked PDF, and the split files keep the same password. The password is not saved. โ–  Privacy PDF contents, file names and passwords are not sent to a server. Ads and optional usage statistics and diagnostics may communicate online as described in the privacy policy, and you can turn usage statistics and diagnostics off in Settings. Large or complex documents may take longer, and some PDFs may not be supported.
