Smallpdf

Smallpdf is a cloud-based PDF toolkit for common document tasks in a web browser. It combines conversion, compression, merging, splitting, signing, and basic editing into a single service, with desktop and mobile apps available alongside the web app.

It is used by individuals, small teams, and office staff who need quick PDF handling without deploying full desktop publishing or prepress software. A distinguishing trait is its broad set of lightweight PDF utilities delivered as simple, task-specific web tools rather than a complex authoring environment.
