What is Smallpdf?

Smallpdf is one of the better known document utility suites, covering the usual ground of merging, splitting, compressing, converting, signing and protecting PDFs, with an AI assistant layered on top for summarising and questioning documents. The interface is deliberately plain, and a desktop application plus mobile apps handle offline and on-the-go work. It is honest to call it a conventional tool with AI features rather than an AI product: most of what people use daily is deterministic file processing, and the free tier is a trial in practice rather than a lasting plan.

FAQ

Is Smallpdf free?

There is a free tier, but it is closer to a trial: around two document tasks per day and some tools reserved for paid accounts. Anyone processing documents regularly will need a subscription.

What does the AI assistant do?

It summarises and answers questions about an uploaded document, similar to other chat-with-PDF tools. It is a convenience on top of the file utilities rather than the reason most people use the site.

Which is better, web or desktop?

The web tools are quicker for one-off jobs and need no install. The desktop app suits repeat work and confidential files, since documents stay on your machine instead of being uploaded.
