How to Split a PDF into Separate Files

Sometimes one PDF is simply too much PDF. A 60-page report goes to five departments, each needing its own chapter. A scanned binder should become one file per document. A course packet has to be handed out page by page. Splitting is the inverse of merging — and, like merging, it does not require a subscription, an installer, or an upload to somebody else’s server.

This guide walks through splitting any PDF into separate files with the free Split PDF tool, running entirely in your browser. It covers the three split modes, when each one is the right choice, and what happens to your downloads.

Step 1: Open the Split PDF tool

Open Split PDF in any modern browser — desktop, tablet or phone — and drop your file on the dropzone. The file is read locally; nothing is uploaded, so there is no queue, no size gate tied to a paid tier, and no copy of your document left behind on a remote server. As with every tool on this site, closing the tab erases every trace.

Step 2: Choose the split mode that matches the job

The tool offers three modes, and picking the right one up front saves you a lot of renaming later:

Custom ranges (the default). Type comma-separated page groups like 1-3, 4-6, 7, and each group becomes its own PDF, in the order you wrote them. This is the mode for meaningful divisions — chapters, sections, one report per client — because you decide exactly which pages travel together. Ranges do not need to be consecutive or cover the whole file: 1-2, 9 produces a two-page file and a one-page file, and skips the rest.

Fixed chunks of N pages. Enter a number — 5 by default — and the document is cut into equal chunks: pages 1–5 in the first file, 6–10 in the next, and so on, with a final shorter chunk if the page count does not divide evenly. Use this when the division is mechanical rather than semantic: email-sized pieces of a large scan, or chunks for a print shop that caps page counts.

One file per page. Every page becomes its own single-page PDF. This is ideal for handouts, individual scanned certificates, page-level review, or any workflow where each page is a standalone document.

Step 3: Split and download

Press Split PDF. Because everything runs on your device, the split takes seconds even on large documents. What you receive depends on the mode: a single output downloads directly, while multiple outputs arrive bundled as one ZIP archive — no fifteen separate download prompts. Unzip it and the files are ready to rename, attach, or share.

The original PDF is never modified; splitting only copies pages into new files. That makes the whole operation reversible and risk-free — if a split comes out wrong, redo it from the same source.

Tips for cleaner splits

• Write ranges before opening the tool. Skim the document, note the real boundaries (“chapter 2 starts at page 13”), and prepare your list. Pasting 1-12, 13-30, 31-44 beats figuring it out mid-task.
• Name for the recipient, not for yourself. After unzipping, rename files to what each recipient expects — chapter-2.pdf, not split-2.pdf. A month later you will not remember what “split-2” contained.
• Split at the end of a pipeline, or in the middle — deliberately. A common pattern: Merge PDF scanned parts into one file, then Split PDF it back into logical documents. The merge-then-split round trip is safe precisely because neither tool touches the originals.
• Need pages scattered across the file, not grouped? If you want page 3, 17 and 41 in one new document rather than three separate ones, that is Extract Pages — splitting groups, extracting collects.

Troubleshooting

The last file has fewer pages than the rest. Normal in fixed-chunk mode when the page count does not divide evenly — the remainder forms the final chunk. Nothing is lost.

A range like 13-9 produced an empty result. Ranges are read literally as written; make sure the first number is the smaller one. Use 9-13.

The ZIP did not arrive. Multiple outputs are bundled automatically; if your browser blocked the download, check its downloads shelf or try again — nothing was processed remotely, so a retry is instant and free.

Can I split a password-protected PDF? Not directly — encrypted files must be opened first. Run it through Unlock PDF with its password, then split the unlocked copy.

Is there a page limit? No account-based limit exists, because there is no account. The practical ceiling is device memory, which comfortably covers the large scans most people encounter.

Splitting is a five-second job once you know which mode fits: ranges for meaning, chunks for size, pages for handouts. Open Split PDF, drop the file, and let the browser do the rest — privately, and for free.
