Three split modes
Extract one range into a single file, produce one PDF per page, or chunk the document into equal groups — covering almost every real splitting need.

Overview
About the Split PDF
Split a PDF online free. Extract a page range, split into single pages, or break at a fixed interval — all processed locally, nothing uploaded.
Splitting is extraction with a purpose: pull the relevant clause out of a 200-page agreement, separate a month's statements from a year's archive, break a scanned booklet into chapters, or turn a single-page-per-file requirement into something a portal will accept.
The three modes
Extract range produces one PDF containing the pages you specify. This is the mode for "I need pages 14 to 19 of this document".
Split every page produces N files from an N-page document. Useful when a system requires one file per page, or when you are preparing pages for individual review.
Fixed-size groups chunks the document into files of a set page count, with the last group holding the remainder. This is the mode for splitting a year of statements into twelve monthly files, or a book into chapters of equal length.
Why output sizes do not add up
People are regularly surprised that splitting a 10 MB PDF into ten pieces produces 30 MB of files in total. The reason is resource sharing. A PDF stores fonts, images and colour profiles once and lets many pages reference the same object. When pages are separated, each new document needs its own copy of everything its pages touch. A document with a large embedded font subset will duplicate that font into every piece.
This is inherent to the format, not a defect in the tool. If total size matters, split into fewer, larger pieces.
Practical tips
- Check the page count first. PDF page numbers and printed page numbers frequently disagree once front matter is involved.
- Use the preview to confirm you have the right range before downloading.
- For documents that will be re-merged later, keep the ranges recorded — the merge tool accepts the same range syntax, so a split-and-merge round trip is straightforward.
- If the source is a scan and you need images rather than a PDF, the PDF to JPG converter with a page range is the faster route.
Step by step
How to use the Split PDF
Upload the PDF you want to split.
Pick a mode: extract a range, split every page, or split into fixed-size groups.
Enter the page range or group size — the tool shows the total page count.
Press Split; each output document is generated separately.
Download the pieces you need individually, or all of them.
Why use it
Benefits and common use cases
What this tool is good for, and what it deliberately does not try to do.
Page-count awareness
The total page count is shown before you commit, and out-of-range values are clamped rather than producing an error.
Keeps content intact
Split pages retain selectable text, embedded fonts, images and annotations because the page objects are copied, not re-rendered.
Nothing leaves your device
Splitting a 300-page contract into clauses or a bank statement into months stays entirely local — which is the whole point.
Questions
Frequently asked questions
Short, honest answers about quality, limits and privacy.
How do I write a page range?
Use commas for individual pages and hyphens for spans, mixed freely: 3, 7-12, 20 produces three groups. Ranges are clamped to the document's actual page count, so 1-9999 on a 40-page file simply yields pages 1 to 40.
Will splitting break digital signatures?
Yes. Any modification to a signed PDF invalidates its signature, and splitting produces new documents. If you need a signed extract, split first and re-sign the result.
Does splitting reduce quality?
No. Pages are copied as page objects, not rendered to images, so text stays vector and images stay at their original resolution. Output size is roughly proportional to the pages extracted.
Why is one of my split files much larger than expected?
PDFs share resources such as fonts and images across pages. When a document is split, each output must carry its own copy of every resource its pages reference, so the parts can add up to more than the whole.
Can I split an encrypted PDF?
Only if it opens without a password. Documents encrypted with a user password cannot be parsed and will be reported as protected.
