Split PDF
Turn one document into the smaller PDFs you actually need.
Static, unencrypted PDF · up to 25 MiB each · 50 MiB total · 200 pages total
Separate output PDFs with semicolons, for example 1-2;3-4. Commas and ranges work inside each group. Groups may overlap.

Page content is copied into a new PDF. Bookmarks, attachments, document-level layers and accessibility structure are not guaranteed to survive page copying. Forms and signatures are not supported. This is not a PDF sanitizer.
Files are processed locally, never uploaded. Download the result before leaving; loaded documents and results are cleared when you leave or reload.
A practical example
Before
4-page PDF · every 2 pages
After
part-001.pdf: pages 1–2 · part-002.pdf: pages 3–4
When this helps
Useful for separating chapters, sharing sections of a handout or dividing scanned documents. Choose a fixed number of pages per part or write custom groups.
How it works and its limits
Every N pages starts at page 1 and creates consecutive parts; the final part can be shorter. Custom groups use semicolons between files, such as 1-2;3-4. A group can contain a comma-separated selection such as 1,3-4.
Custom groups may overlap, so one source page can appear in different output PDFs. Repeating a page within a single group is rejected. Pages outside the listed custom groups are omitted.
One part downloads as a PDF; multiple parts are packaged in a ZIP. Document-level structures are not transferred. Source PDFs must be static and unencrypted, with at most 200 pages. Large repeated resources can increase total output; the output cap is 60 MiB.
Useful details
Does splitting delete pages from the original?
No. It creates new files.
Can a page appear in two parts?
Yes, if you deliberately include it in two custom groups.
Why is the last part shorter?
In fixed-size mode the final part contains the remaining pages.
