PDF tools

Merge, split, rotate and reorder PDFs entirely on your own machine. Contracts, invoices and HR documents never touch a server.

Nothing here is uploaded

These tools are ordinary web pages that happen to contain the whole program. When you choose a file, your browser reads it from your disk into its own memory and the work happens there. There is no upload step, because there is nowhere for it to go — the site is static files with no backend.
