Split a PDF
Cut one PDF into several files.
Add every file you want to join, drag them into the order you want, and download one PDF. Each file keeps its own page size and orientation, so a landscape scan dropped between two portrait reports stays landscape. If you only want part of a file, pick its pages before you merge rather than merging and then deleting.
What it does
This tool runs entirely inside your browser tab. The file never leaves your machine, using it needs no sign-up, downloading needs only a free account, and nothing you download carries a watermark.

Questions
There is no fixed limit. The tool runs on your own machine, so the practical ceiling is what your browser can comfortably hold in memory.
