Split PDF Pages
Split a PDF by single page, fixed group size, or custom ranges
About this tool
Split into one file per page, strict whole-number batches, or semicolon-separated custom groups. Every group is validated before output starts, and all files are published together. One PDF with 1–80 pages and up to 20 MiB. Up to 80 output PDFs, 480 total output pages and 100 MiB combined output. Forms, XFA, widgets, signature permissions and portfolios are rejected. Digital signatures do not remain valid; outlines, attachments and cross-page destinations are not rebuilt. Review ordinary annotations after downloading. PDF content is processed locally, with manual downloads after the complete operation succeeds.
Suggested Workflow
Check Booklet Page Order: Eight Pages, Seven Pages, and Duplex Printing
Follow numbered PDF samples to verify booklet front/back pairs, a padded blank slot, reading direction, and the difference between PDF sides and paper sheets.
Document Handoff: Split a PDF, Check Extracted Text, and Deliver the Right Version
Prepare smaller PDF bundles, choose text extraction or OCR, check a known passage, and make the recipient’s version and access instructions clear.
Scenario Recipes
Separate a report into explicit overlapping selections
Goal: The two outputs have distinct sequential filenames even though both start at page 1 and end at page 3. Repeated and omitted source pages are disclosed.
- Choose Custom ranges and enter 1,3;1-3 for a six-page source.
- Review both exact mappings, the shared pages 1 and 3, and omitted pages 4–6.
- Confirm and generate. Download both numbered files and check their page lists.
Result: New PDFs match the reviewed source-page mapping and are downloaded manually for inspection.
Failure Clinic (Common Pitfalls)
A later group contains a typo
Cause: An empty token, trailing semicolon or out-of-range page makes the complete plan invalid.
Fix: Correct every group before generating. No earlier file is exposed if a later output fails.
Generated files disappear after a change
Cause: Output bytes belong to the source files and settings used to create them.
Fix: Review and generate again after changing options, order, sources, clearing or switching language. Old downloads do not continue.
A form or signed document is rejected
Cause: Forms, XFA, widget annotations, signature permissions and portfolios are rejected. Page copying does not preserve valid digital signatures or rebuild outlines, attachments and cross-page destinations. Ordinary annotations need output review.
Fix: Use an export or flattening workflow that explicitly supports those features, and retain the original document.
Production Snippets

text
Input: A1,A2,A3,A4,A5,A6
Custom groups: 1,3;1-3
part-01.pdf → A1,A3
part-02.pdf → A1,A2,A3
Repeated across outputs: 1,3; omitted: 4,5,6Frequently Asked Questions
Can custom groups overlap or omit pages?
Yes, when explicitly requested. For 1,3;1-3, pages 1 and 3 appear in both outputs, while later source pages are omitted. The preview lists both conditions.
Why do files use part numbers instead of range endpoints?
Groups 1,3 and 1-3 have the same endpoints but different contents. Sequential filenames distinguish them reliably.
Will the first parts download if a later part fails?
No. Every group must validate and every file must finish before the download list appears. A failed or cancelled operation exposes no partial batch.
What are this tool’s file and page limits?
One PDF with 1–80 pages and up to 20 MiB. Up to 80 output PDFs, 480 total output pages and 100 MiB combined output.
