How to split a PDF on a Mac without uploading it
By Himanshu Ranjan · Updated 8 November 2026
To split a PDF on a Mac with FileDial, select it in Finder, hold the right Option key and choose Organize › Split every page for one PDF per page. Use Split by ranges… or Split into chunks of N… for groups of pages, or Extract pages… to pull out just the ones you need. New files appear beside the original, which stays untouched, and nothing is uploaded.
How to do it with FileDial
- Select the PDF in Finder.
- Hold right ⌥ and choose Organize.
- Pick Split every page, Split by ranges…, Split into chunks of N… or Extract pages…
- Enter the ranges or chunk size when asked.
- Find the new PDFs beside the original; Undo removes them if you change your mind.
Your original file stays untouched. The result is saved beside it, and every result has Undo.
Which option to pick
| Tool | Use it when |
|---|---|
| Split every pageOrganize | You need each page as its own PDF, for example separate invoices scanned together. |
| Split into chunks of N…Organize | Breaking a long file into equal parts of N pages; new copies go beside the original. |
| Split by ranges…Organize | You know the page ranges, such as chapters or statements; one PDF per range. |
| Extract pages…Organize | You only need a few pages out of a larger document; a new copy goes beside the original. |
| Split double-page scansOrganize | A book or booklet scanned two pages per sheet: each landscape page becomes left and right pages, nothing deleted. |
Choosing the right kind of split
Splitting is usually about sending only what someone needs. A landlord asking for your latest bank statement does not need the other eleven months, and an HR portal asking for page two of a contract does not need the salary schedule. Extract pages is the right tool when you want one small file out of a big one; split by ranges is better when the whole document divides into meaningful parts.
Chunks of N is useful for fixed-size limits: some portals accept only a set number of pages per upload, and equal chunks keep each part predictable. Split every page suits batches of single-page items, such as receipts scanned in one pass, where each page should become its own file you can rename and file away.
Double-page scans are their own problem. When you lay an open book on a flatbed or photograph a booklet, each image holds two pages side by side. Split double-page scans cuts each landscape page into its left and right halves, so the result reads like the original book.
Why not split it on a website?
To get two pages out of a document online, you upload the entire document, including every page you meant to keep private. That is a poor trade when the file is a full tax return or a contract. Cybernews reported in July 2024 that two online PDF services left storage open and exposed 89,062 user-uploaded files, including passports, IDs, certificates and contracts; the providers did not respond.
FileDial splits the PDF locally. Nothing is uploaded, all tools work with Wi-Fi off, and the original is never changed.
Other ways to split a PDF on a Mac
Preview can do simple splits. With the sidebar showing thumbnails, you can drag a page thumbnail to the desktop to make a separate PDF of that page. You can also use File › Print, choose a page range, and save the output as a PDF from the PDF menu in the print dialog.
These are fine for one-off jobs. FileDial is faster for anything repetitive: one PDF per page in a single step, several ranges at once, equal chunks, splitting double-page scans, batches of files, and Undo on every result.
Questions
Does splitting a PDF change the original file?
No. Each split creates new PDFs beside the original, and the original stays as it was. Every result has Undo, so you can remove the new files in one step.
Can I split several PDFs at once?
Yes. FileDial works in batches: select many PDFs in Finder and run one tool, such as Split every page, on all of them. Each file's parts are saved beside that file.
Does it work offline?
Yes. Splitting runs on your Mac and works with Wi-Fi off. Files are never uploaded, so there is no website size limit, and pages you meant to keep private never leave the Mac.
Will split pages lose quality?
The split tools' notes describe copying pages into new PDFs, with no compression step. Split double-page scans cuts landscape pages into halves and deletes nothing.
Is it free?
FileDial has a 1-day free trial of every tool with no card or account. After that it costs $20 once for a lifetime licence on 2 Macs, with a 14-day refund.
