What Split PDF does
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.
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.
How to split pdf in your browser
- Choose one PDFSelect one PDF from the dropzone. Filozy reads it locally and shows the relevant preview or controls before changing anything.
- Review the settingsAdd 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.
- Create and check the resultRun the tool, review the reported page count, size, or notes, then save the newly created file while keeping the original.
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.
Limits worth knowing
- Smart separators depend on the PDF text layer, bookmarks, or rendered blank-page detection. Review every detected boundary.
Frequently asked questions
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.
