About ZasPDF
ZasPDF is a set of professional PDF tools — merge, split, encrypt, rotate, reorder and more — that run entirely on the user's device: a Go/WebAssembly engine is downloaded once into the browser tab and then processes files locally, even in airplane mode, with nothing uploaded to any server. No account is required for any tool; an optional account only syncs preferences with the companion mobile apps. The service is funded by advertising.
