Break a PDF into multiple files. See every page as a thumbnail, colour-coded by which output file it goes into — then preview the whole plan before downloading.
Single file · up to 200 MB · password-protected PDFs supported
Every page is shown as a thumbnail, coloured by the output file it'll go into. Change the mode and watch the groups update live.
Pick "Click to split" and tap the gap between any two pages to add a cut-line. Tap again to remove it.
Click "Preview split plan" to see every page grouped into its output file, with clear labels and zoom controls.
Nothing uploads anywhere. The PDF is opened, processed, and exported entirely in your browser.
