Split PDF

What is Split PDF?

Split PDF is a free, browser-based tool for extracting pages or splitting a PDF into separate files. Use it to pull a custom page range into a new PDF, or to break a multi-page document into individual single-page PDFs. People reach for it to extract specific pages, keep only the pages they want, reorder pages (reversed ranges work), or split a scanned document, contract, or report into per-page files. It is built on pdf-lib and works on any PDF you drop in, showing the total page count and a clickable first-page thumbnail before you act. Beyond a typed range, you can click page thumbnails to build the selection, reorder chosen pages, split into fixed chunks (every N pages or by megabytes), and grab everything as a single ZIP archive.

How to use Split PDF

1. Drag and drop a PDF onto the dropzone (or click to choose a file). The tool loads it and shows the total page count plus a first-page preview you can click to enlarge.
2. Type a page range in the Page range field, 1-based, like "1-3,5,8-10". Separate parts with commas; the order you type is preserved and reversed segments (e.g. "10-8") are allowed. By default the field is pre-filled with the full range (1 to the last page).
3. Click "Extract pages" to build a single new PDF containing only the selected pages, in your chosen order, and download it.
4. Or click page thumbnails to build the selection visually, reorder chosen pages with the move buttons, and open Split options (gear) to split every N pages or by target size — optionally downloading all pieces as one ZIP.
5. Or click "Split into single pages" to turn every page of the document into its own one-page PDF file, downloaded as a numbered set (the range field is ignored for this action).
6. Optionally tick "Keep this page range when a new PDF is loaded" to reuse the same range across multiple files, or use Reset to clear the file and start over.

Frequently asked questions

Is my PDF uploaded to a server?

No. Everything runs 100% client-side in your browser using pdf-lib. Your document is read and processed locally and is never uploaded, so it stays private even for confidential files.

How do I write the page range?

Use 1-based page numbers separated by commas, for example "1-3,5,8-10". A single number like "5" selects one page, and a hyphen makes a span. The order you type is preserved in the output.

Can I reverse or reorder pages?

Yes. Reversed segments such as "10-8" output pages in descending order, and you can mix parts (e.g. "3-1,5") to build any order you want. The extracted PDF follows your typed sequence exactly.

What's the difference between Extract pages and Split into single pages?

Extract pages combines just your selected range into one new PDF. Split into single pages ignores the range and turns every page of the document into its own separate one-page PDF file.

Why do I get an "Out of range" or "Invalid segment" error?

Out of range means a number you typed is below 1 or above the document's total page count. Invalid segment means a part isn't a valid number or number-range. Fix the range to match the shown total pages and the example format.

Can I split by page count or file size, and download a ZIP?

Yes. In Split options pick Every N pages to cut the document into fixed-size chunks, or By size to keep each part under a target number of megabytes. Turn on the ZIP option to download all the split PDFs as a single archive instead of separate files. The page-thumbnail grid also lets you click to select pages and reorder them before extracting.
