How to split a PDF online
The setting controls repeated groups from page 1 onward. Check the source and predicted counts before creating the ZIP.
- Step 1
Choose one readable PDF
Select the source document. After it is read successfully, the workspace shows its filename, size, and page count.
- Step 2
Set pages per output file
Enter a whole number from 1 through the source page count and check how many sequential PDF parts will be created.
- Step 3
Split and download the ZIP
Choose Split PDF, confirm the generated PDF count and archive size, then download all parts together.
Plan sequential PDF parts
This splitter starts at page 1 and creates repeated groups using the number you choose. The predicted count helps you check the plan before processing.
Larger values create fixed page groups
A 7-page PDF split by 3 pages creates page groups 1-3, 4-6, and 7. Groups stay in the original sequence.
The final part can be shorter
When pages do not divide evenly, the last PDF contains only the remaining pages. The tool does not add blank pages to make groups equal.
What each split file contains
The tool copies complete source pages into new PDF documents. It separates pages without turning them into images, but document-level behavior still needs review.
Complete pages are copied into new PDFs
This operation does not crop pages, run OCR, edit text, or compress page content. Each selected page group is copied into a new PDF part.
Filenames show each source page range
Files inside the ZIP use names such as part-1-pages-1-3.pdf, making the original page range visible before you open a part.
Review document-level features
Bookmarks, signatures, interactive forms, attachments, metadata, page labels, or accessibility structures may not behave like the source after splitting. Inspect important outputs.
PDF splitter or page extractor?
Choose the tool based on the page pattern you need. Fixed sequential groups and exact page selections are different document tasks.
Use the splitter for repeated page groups
Choose this page when you want every 1, 2, 5, or another fixed number of sequential pages placed in separate PDFs.
Use extraction for exact pages or ranges
Choose PDF Page Extractor when you need a selection such as pages 1-3, 5, and 8-10 combined into one new document.
Merge or rebuild only as a follow-up
Use PDF Merger later if selected split parts or other complete PDF documents need to be combined in a new order.
Privacy and limits
Your selected PDF is processed locally in this browser while the split files and ZIP are created. This free online tool requires no registration or login.
- This mode accepts one readable PDF and splits it into sequential groups by pages per file. It does not use custom ranges, visual split points, bookmarks, file-size targets, or multiple source PDFs.
- Encrypted, password-protected, damaged, malformed, or unsupported PDFs can fail to load. Large documents depend on the memory available to the current browser and device.
- The ZIP keeps the generated parts together, but important output should be reviewed for page order, readability, bookmarks, signatures, forms, attachments, metadata, page labels, and accessibility behavior.
PDF Splitter FAQ
Answers about sequential page groups, single-page files, ZIP downloads, local processing, source limits, and selected-page alternatives.
How do I split a PDF online?
Choose one readable PDF, enter the number of pages for each output file, review the expected part count, choose Split PDF, then download the ZIP when it is ready.
Is this PDF splitter free?
Yes. This is a free online browser tool with no registration or login required.
Do I need an account or login?
No. You can select a supported PDF, split it, and download the result without creating an account or signing in.
Is my PDF uploaded?
No. The selected PDF is read and split in this browser while the tool runs; the tool does not send the source document to an external processing service.
What does pages per output file mean?
It is the maximum number of sequential source pages placed in each generated PDF. For example, a 7-page source with 3 pages per file produces parts for pages 1-3, 4-6, and 7.
How do I split every page into a separate PDF?
Set Pages per output file to 1. The ZIP will contain one single-page PDF for every source page.
What happens when the page count is not evenly divisible?
The final generated PDF contains the remaining pages, so it can be shorter than the earlier parts. A 7-page source split by 3 pages creates two 3-page files and one 1-page file.
Why does the result download as a ZIP?
Splitting usually creates several PDF files. The ZIP packages every generated part into one browser download while keeping each PDF separate inside the archive.
Can I split by custom page ranges, bookmarks, or file size?
No. This splitter creates repeated sequential groups of pages from page 1 onward. Use PDF Page Extractor for exact pages or ranges such as 1-3, 5, 8-10. Bookmark-based and target-file-size splitting are not available.
Does splitting change the original PDF?
No. The source file on your device is not overwritten. The tool reads it and builds new PDF parts in browser memory, then packages those outputs into a ZIP.
Why could a PDF fail to open or split?
Encrypted, password-protected, damaged, malformed, or unsupported PDFs may not be readable. Very large files can also exceed the memory available to the current browser or device.
