What is Split PDF used for?
Purpose
What does Split PDF do?
Use Split PDF to separate a document with cuts between visible pages or custom page groups. Each comma-separated group produces a separate PDF. For equal parts, size targets, bookmarks or smart separators, follow the advanced splitting link to Split by size or bookmark. Your selected document, its filename, and its contents stay on your device.
Who normally uses it?
This guide is useful for people preparing reports, scanned packets, submissions, records, and documents whose page order matters. The working tool is focused on one outcome: Cut between visible pages or enter your own page groups.
Prepare
Before you start
- Keep the original file until the new document has been opened and checked.
- Use the visible page thumbnails to confirm page order, orientation, and the exact pages being changed.
- Remember that printed page labels can differ from the PDF page number shown by the browser.
Step by step
How do I use Split PDF?
- 01
Choose one PDF
Select one PDF from the dropzone. Filozy reads it locally and shows the relevant preview or controls before changing anything.
- 02
Review the settings
Add cuts between pages in the preview or enter groups such as 1-3, 4-6, 9. Check that every page you need is included; each comma-separated group becomes its own PDF.
- 03
Create and check the result
Run the tool, review the reported page count, size, or notes, then save the newly created file while keeping the original.
Better results
Practical tips for Split PDF
Zoom the thumbnail view when two pages look similar, especially in scanned document batches.
For a very large document, test the intended settings on a small page group first.
Check the output page count and file order in the result receipt before saving or sharing.
Honest expectations
Limitations and important checks
Smart separators depend on the PDF text layer, bookmarks, or rendered blank-page detection. Review every detected boundary.
Questions and answers
Split PDF FAQ
Direct answers to the questions people commonly ask before using this tool.
What is Split PDF used for?
Split PDF is a browser-based Filozy tool built for this task: Cut between visible pages or enter your own page groups. It runs on this device, creates a separate result, and does not require an account or document upload.
Can I use Split PDF on a phone or tablet?
Yes. Split PDF works in a current mobile browser. Complex PDFs can need more memory, so keep the tab open, avoid switching apps during processing, and inspect the result before closing the page.
Does Split PDF upload my file?
No. The selected file is opened and processed by code running in this browser tab. Document bytes and filenames are not sent to Filozy.
Will this change my original file?
No. Browsers cannot silently overwrite the file you selected. Filozy creates a separate result for you to save or pass to another local tool.
What should I check after using Split PDF?
Check the cuts, page groups, output count and filenames. Open each result to confirm its pages. Pages omitted from your groups will not appear in the split results, but your original file is unchanged.
Where can I split by file size, bookmarks or blank pages?
Use the advanced splitting link in this tool, or choose Split by size or bookmark from the tool library. That tool also offers every N pages, equal parts and page-start text. Size targets are approximate and text matching needs a readable PDF text layer.
Do I need an account or subscription?
No account is required for this browser-side tool. It runs on the device and does not use a document-upload allowance or daily server quota.
Privacy
Where does my document go?
For this tool, the document stays in the browser tab. Filozy can load same-origin support files such as its PDF engine, fonts, or OCR data, but the selected document bytes and filename are not sent with those requests.
