Split runs in your browser so we do not host every PDF. Your file is not uploaded by default.
1Choose a PDF
Drop one PDF on this page, or use the file button. The split program loads after you choose it, not when the page first opens. If the file asks for a password, unlock it on Unlock PDF first. We do not guess passwords.
2Drag pages into output boxes
Visual split is the default, next to a shorter written-list option. The page cards are on top. Under them, each output file is a large box, and the next box sits to its right. Drag pages such as 1, 3, and 8 into a box. Inside the box they stay cards: drag them left or right to set that file's order. A page you never drop in is left out. The same page can go in more than one box. If you would rather type, one line is one file, and 11, 9, 10 stays in that order. With more than 20 pages the cards stay hidden unless you ask to see them. Extract-one-PDF and one-file-per-page are still lower on the page.
3Download the files
Processing runs in a Web Worker on this device after you press Split. We keep that work local so we do not pay to split every upload on our servers. By default the PDF is not uploaded. Each group downloads as its own file, named part-001.pdf and so on. There is no zip. Extract still saves one PDF. Explode still lists one download per page.
Is my PDF uploaded when I split it?
By default, no. Split runs in your browser so we do not host or split every PDF on our servers. Open DevTools, select Network, split a file, and confirm the PDF is not posted to a remote host. Page assets may still load from this site; the PDF itself is not sent on the default path.
Can I split into several multi-page files?
Yes. That is the default visual path. Add an output box, then drag pages into it from the cards above. Inside a box, drag cards left or right to set order. Above 20 pages, type one line per file instead unless you choose to show the cards. Pages you never place are left out. The same page can go in more than one file. Repeating a page on the same line is rejected.
If I type 11, 9, 10, which order do I get?
The order you write, or the order you drag inside a box. Writing 11, 9, 10 becomes page 11, then page 9, then page 10. The numbers are not sorted. A range such as 1-3 still expands forward as pages 1, 2, 3.
Where does Split PDF run?
Split runs in a Web Worker inside your browser. Local processing is how we avoid server-side split jobs. The heavy split code loads only after you choose a file.
What is the difference between extract and explode?
Extract writes one PDF that contains only the pages you listed, in that order. Explode writes a separate one-page PDF for each selected page. Choose extract when you want a single file; choose explode when you want one download per page. The main visual path builds several multi-page files by dragging pages into boxes instead.
Does explode download a zip of the pages?
No. Explode produces one PDF download per selected page, listed on this page. There is no zip archive and no bundled package. Save each page file you need. The same is true for visual split: each output file downloads on its own.
What file size and page limits apply?
The current limits are 100 MB and 200 pages. Larger files are rejected with a clear error.
Can I split a password-protected PDF?
Encrypted PDFs and files that need a password to open are rejected with a clear error. Unlock the file on Unlock PDF first if you already know the open password or only need to clear a permission lock, then come back to split. This site does not recover or guess passwords.
Is Split PDF free?
Yes. Split PDF is free in your browser and does not use credits. No account is required. You still have to stay within 100 MB and 200 pages.
