What does Split PDF do?
Split PDF separates pages from one PDF into new PDF output. The workflow is focused on dividing a document rather than combining several files.
How to split a PDF
After upload, Docelora reads the PDF in your browser to show a visual preview of its actual pages. Select the pages you want, then the selected document is sent to the Docelora processing service for the split job.
Split methods
One file per page
Each selected page is processed as its own PDF.
Fixed-size chunks
Choose how many pages belong in each output group.
My own ranges
Enter ranges such as 1-4, 7, 10-12 for a custom selection.
