# FreeLocalConverter

> FreeLocalConverter: free browser-based CSV, JSON, PDF, image, and data conversion tools that run locally in your browser without server uploads. Processing is intended to run locally in the visitor's browser where a tool supports it; sensitive file contents are not sent to our servers for those client-side flows. The site is multilingual: English URLs omit a locale prefix (`localePrefix: as-needed` in next-intl). Other locales use paths like `/de/...`, `/fr/...`, etc.

## For automated agents

Prefer localized URLs when the user's language is known. Paths above are English defaults; use `https://freelocalconverter.com/{locale}/path` for non-English locales (zh, es, pt, fr, de, nl, it, ja, tr, az, ko, ar, fa, ru, he, el).
