Split PDF Files Online

1. 1

   Add your PDF

   Drop a PDF onto the tool or browse for one. Every page appears as a thumbnail with its number, so you can see what you are splitting before you choose anything.

2. 2

   Choose how to split it

   Pick one of seven ways: one file per page, custom ranges like 1-5, 10, 15-20, every N pages, split points clicked between thumbnails, the pages you tick gathered into one file, top-level bookmarks, or parts that each stay under a size you set.

3. 3

   Check the outcome line

   The rail says how many files your settings will produce before anything runs — for example 12 pages into 4 files. Adjust the range, the split points or the size until that number is what you want.

   Split and download

   Press Split. Each file appears with its page range, its size and a preview. Download them one at a time, or take everything in one ZIP. Nothing is uploaded — the whole split happens on your device.

Splitting a PDF lets you pull out the pages you actually need: one signed page from a contract, a single chapter from a manual, or a hundred-page scan broken into files small enough to email. This tool splits a PDF into separate files by page ranges or extracts single pages, and it does the whole job on your device — the document is never uploaded, so there is nothing to wait for and nothing to trust.

Benefits of PDF Splitting

• Page Extraction: One PDF per page, custom ranges, or exactly the pages you tick
• Chapter Splitting: One file per top-level bookmark, each named after it
• Size Budgets: Parts that each stay under a file size you choose
• Custom Names: Set the output base name once and every file follows it
• Page Thumbnails: See every page before you split, and click to choose
• Download Options: Take files one at a time or everything in one ZIP

Different documents want different cuts, and typing page numbers is the wrong answer for most of them. Each method below produces the same lossless files; the difference is how much work it takes you to describe what you want.

Choosing a Method

• One file per page: Every page becomes its own PDF. The right choice when you are feeding pages into another system one at a time.
• Page ranges: Type 1-5, 10, 15-20 and get three files. Each range you list becomes one file, in the order you list it.
• Every N pages: Fixed groups — every 2 pages, every 10 pages. A 12-page document split every 5 gives files of 5, 5 and 2.
• Split points: Click the gap between two page thumbnails to place a cut. Three cuts give four files, and you never type a page number.
• Extract ticked pages: Tick pages 3, 7 and 12 and get one file containing exactly those three, in page order.
• At bookmarks: One file per top-level bookmark, named after it. The fastest way to break a book into chapters.
• Target file size: Set a budget and pages are packed into as many files as it takes to stay under it.

A page range is a description of something you are already looking at. Split points remove that translation step: the page thumbnails are the control, and clicking the gap between two of them places a cut there. The gap shows a dashed line before you click and a solid one after, so the shape of the split is visible at a glance rather than held in your head.

When Split Points Win

• Scanned batches: Several documents fed through one scanner — cut where each new letterhead starts.
• Uneven sections: Chapters of 4, 11 and 6 pages are three clicks, and three ranges to type.
• Checking as you go: Every cut is undone by clicking it again, and the file count updates as you work.

A PDF built from a word processor or a typesetting system usually carries an outline — the clickable tree of chapters a reader sees in the sidebar. Split at bookmarks reads that outline and starts a new file at each top-level entry, naming each file after the bookmark it came from. Nested sub-entries are deliberately ignored: splitting on them as well would turn a ten-chapter book into fifty fragments.

What to Expect

• One file per chapter: Each top-level bookmark starts a file that runs to the page before the next one.
• Named from the outline: Chapter Two becomes report_Chapter Two.pdf, cleaned of anything a filename cannot hold.
• Nothing is dropped: Pages before the first bookmark — a cover, a contents page — are kept as their own file, and the tool says so.
• No outline, no guessing: A PDF without bookmarks says so and points you at split points instead of silently producing one file.

Mail servers and upload forms have limits, and "about half" is not a way to hit one. Target file size measures every page on its own first, then packs pages into files that each stay under the budget you set. The measurement is real — each page is written out and its actual size recorded — so the answer accounts for the images and fonts a page really carries rather than assuming pages weigh the same.

How the Budget Is Honoured

• Measured, not estimated: Every page's own weight is recorded before any grouping happens.
• Order is preserved: Pages are packed in reading order, so part 2 always follows part 1.
• Heavy pages are named: A page larger than the whole budget cannot be made to fit; it gets its own file and the tool tells you which page it was.
• The budget is yours: Set it in megabytes to match the mailbox, the form or the drive you are aiming at.

Splitting a PDF is not a conversion. A PDF is a graph of objects — pages, fonts, images, content streams — and extracting a page means copying that page's part of the graph into a new document. Nothing is decoded and nothing is re-compressed, which is why a split file opens identically to the page it came from and why the operation is fast enough to feel instant.

Splitting Methods

• One PDF per page: Each page becomes its own file
• By page range: Enter ranges like 1-5, 10, 15-20 for separate files
• Every N pages: Split into parts of N pages each
• Custom output name: Base name used for all split filenames
• Preview & ZIP: Built-in preview and download all as ZIP

Understanding these facts helps you make better splitting decisions.

Key Statistics

• PDF splitting preserves original quality — pages are copied, not re-encoded
• Every page is previewable before and after the split
• Custom output base names carry through to the ZIP
• Page order is preserved in every method
• Seven methods: per page, range, every N, split points, ticked pages, bookmarks, target size
• Page size, rotation and embedded fonts survive the split unchanged

Follow these guidelines for optimal PDF splitting results.

Quality Considerations

• Use the thumbnails to confirm page count and content before splitting
• Choose the method that matches how you already think about the document
• Read the outcome line — it says how many files you will get before anything runs
• Set a clear output base name so the files are identifiable after download
• Preview individual files before downloading, then take everything in one ZIP
• Check the notice under the range field: pages a range cannot reach are listed, never dropped in silence

Common Use Cases

• Page Extraction: Pull one signed page out of a contract without sending the rest
• Chapter Splitting: Break a bookmarked manual into one file per chapter
• Email Attachments: Split a large scan into parts that each fit the size limit
• Scanned Batches: Cut a single scan of several documents at the points you can see
• Selective Sharing: Gather just the pages someone asked for into one file

The document is read once and kept open. Each file you asked for is built by copying its pages out of that one parsed document into a fresh one, which is then written out. The reading, the copying and the writing all happen on a background thread, so the page stays responsive even while a hundred files are being produced — and none of it involves a server.

Splitting Process

• Read & Preview: The document is parsed once. Page count, page sizes, rotations and the bookmark outline are read without decoding a single picture, and thumbnails are drawn only for the pages on screen.
• Plan: Your settings become an exact list of files before anything is written, which is what lets the rail tell you how many files you will get.
• Copy: Each file is built by copying whole pages out of the parsed document. Content streams, fonts and images come across untouched, so nothing is re-compressed.
• Write: Each file is written out on a background thread, reporting progress as it goes, and can be cancelled without losing the files already finished.
• Download: Take files individually, or collect all of them into a single ZIP with cleaned, de-duplicated names.

Pages are copied, never re-encoded, and the work runs on a background thread so the page stays responsive.
