What Split PDF does
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.
Limits worth knowing
- This workflow stops on interactive forms rather than risk losing their fields. Use Flatten first and check every visible answer in that saved copy, then open the flattened PDF here. Keep the editable original; protected or XFA forms may need a compatible form application first.
Essential questions
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.
