About SmallNook

SmallNook is a collection of small, fast, free online tools — file converters, calculators, and generators that do one job well and get out of your way.

Your files stay on your device

Wherever technically possible, our tools run entirely in your browser. When you convert an image or merge a document here, the processing happens on your own computer or phone — the file is never uploaded to a server. That makes the tools faster (no upload wait) and private by design.

Free, supported by ads

Every tool is free, with no signup, no watermarks, and no artificial limits. The site is supported by unobtrusive advertising, which keeps the tools free for everyone.

Who runs this

SmallNook is built and maintained by a small independent team in Croatia. We use these tools ourselves, and we add new ones regularly. If something is broken or missing a feature you need, tell us via the contact page — we read everything.
