# Acrafto

> Free online tools that run entirely in the browser: image editing and conversion, unit converters, password and random generators, developer utilities, text tools and date calculators. Files are processed locally and never uploaded to a server. No sign-up.

Tools are interactive browser apps; there is no public API, no endpoints to call and no server-side processing. To use a tool, open its HTML page in a browser.

Links below are the English versions. Every tool also exists in 38 languages under `https://acrafto.com/{lang}/{localized-slug}/`; slugs are translated, so use the language's own llms.txt (see Languages) to find the right URL. Tool links point to Markdown versions (`index.md`) with the page text; the interactive tool is at the same URL without `index.md`. Each tool's Markdown lists its URLs in all other languages.
