# LocalPapa Knowledge Pack

LocalPapa (<https://localpapa.com/>) is a collection of **53 free online tools that run 100% in the browser** — files and data never leave the user's device (no upload, no account). Tools cover PDF, audio, images, developer utilities, device sensors and more.

This is an [Open Knowledge Format](https://cloud.google.com/blog/products/data-analytics/how-the-open-knowledge-format-can-improve-data-sharing/) bundle: a clean, linkable Markdown map of the site for AI agents.
