What is the split pdf?

Split PDF divides one PDF into several smaller files using pdf-lib in the browser: burst every page into its own file, or type custom ranges like 1-3, 4-8, 9 to carve out sections. Preview pages on a thumbnail grid, then download the results separately or as one ZIP. Free, watermark-free, nothing uploaded.

The GigAI PDF Splitter takes a single PDF and divides it into several smaller documents without sending a byte to a server. Upload your file, see every page rendered as a thumbnail, and choose how to divide it: 'every page' produces one single-page PDF per page, while 'custom ranges' lets you type ranges like 1-3, 4-8, 9 to slice out exactly the sections you need. Everything is assembled locally with pdf-lib, so the original page content (text, images and vectors) carries across untouched, there's no page cap and no watermark. When you're done, download each split file individually or grab them all in one ZIP.

How to use the split pdf

  1. 1

    Upload your PDF

    Drag a single PDF onto the drop zone, or click to browse. Its pages render as thumbnails so you can see what you're working with.

  2. 2

    Choose a split mode

    Pick 'Every page' to make one file per page, or 'Custom ranges' and type the ranges you want, like 1-3, 4-8, 9.

  3. 3

    Split

    Hit Split PDF. The tool builds each smaller document locally, in a moment, with no upload.

  4. 4

    Download

    Download each split file, or grab them all at once as a ZIP. Need a different cut? Adjust the ranges and split again.

What Split PDF includes

  • Visual page picker

    Every page is rendered as a thumbnail so you can see exactly what you're splitting. Set your split points against the real document, not a page number you're guessing at.

  • Two split modes

    Choose 'every page' to burst the PDF into one file per page, or 'custom ranges' to type sections like 1-4, 5-9 and get one file per range: whichever fits the job.

  • Download all as a ZIP

    Splitting a big document makes lots of files. Grab them one at a time, or download the entire batch bundled into a single ZIP with one click.

  • 100% in your browser

    Your PDF is read and split locally with pdf-lib. It's never uploaded, stored or seen by anyone, the privacy promise holds for every page you cut.

  • Original quality kept

    Each split file copies its pages over as-is. Text stays selectable, images keep their resolution and nothing is re-rendered or compressed on the way out.

Why use our split pdf

See before you split

The thumbnail grid shows every page, so you set split points against the actual content. No more re-splitting because a range was off by one page.

Private by design

Splitting runs entirely inside your browser tab. Your document never leaves your device, so there's nothing for us to upload, store or read.

Free with no limits

No account, no daily cap, no paywall and no watermark. Split a two-page memo or a 500-page manual as often as you like, at no cost.

One file becomes many, cleanly

Each output is a complete, standalone PDF named after its source and pages, easy to file, email or upload individually.

Built for the way you work

From quick one-off fixes to daily workflows, see how people put this tool to use.

  • Professional

    Send only the relevant section

    Split a long contract so you can email a counterparty just the signature pages or the schedule they asked for, without forwarding the whole document.

  • Student

    Separate a scanned lecture pack

    Break a combined PDF of scanned handouts into one file per topic, so each week's reading is its own document you can revise independently.

  • Business

    Burst a batch of statements

    Split a merged run of monthly statements or payslips into one PDF per page, ready to file or distribute to the right recipient.

Supported formats

Common problems, solved

Hit a snag? Here are quick fixes for the issues people run into most.

  • My custom ranges produced fewer files than I expected.

    Each comma-separated range becomes exactly one file. '1-3, 4-6' makes two files (pages 1-3 and 4-6). If you want one file per page, use 'Every page' mode instead.

  • I get an 'out of bounds' error when I split.

    A range references a page this PDF doesn't have. Check the highest page number against the thumbnail grid: ranges are inclusive and 1-based, so '1-10' needs at least ten pages.

  • The page previews won't load.

    The file may be password-protected or corrupted. Remove the password with our Unlock PDF tool first, or re-save the document from its source, then upload it again.

Get the most out of it

  • Use 'Custom ranges' to keep chapters together, type each chapter's page span as its own range for cleanly divided files.

  • Ranges are inclusive: '4-4' or just '4' both extract a single page as its own PDF.

  • Splitting hundreds of pages? Download the ZIP rather than clicking each file. It bundles the whole batch in one go.

  • Want the opposite: several files into one? Combine your split pieces back together with our Merge PDF tool any time.
