About Pocket Caliper

A workbench, not a warehouse

Pocket Caliper is a set of small, specific tools. Each one has its own page, its own explanation, and a job you can finish in a minute.

We keep the interface quiet so the input and the result stay obvious on a phone and on a desktop.

Private by default

Client-side tools process your content in the browser. We do not upload your drafts, JSON, or images to run the current catalog.

If a future feature ever needs a server, that page will say so before you use it.

Built for search and speed

Every tool is a real HTML page with unique copy, canonical URLs, and language alternatives. The interactive part hydrates only where you need it.
