# AllThatConverter

AllThatConverter is a free, browser-based file conversion and editing suite. Users convert and edit audio, video, raster and vector images, and PDFs without uploading files to a server: processing runs locally with WebAssembly (FFmpeg) and client-side libraries where applicable. The site includes a dedicated Text hub (JSON beautify/minify plus UUID generator, counters, whitespace and line-break helpers, line-based text compare), a special-character and symbol picker under Tools (tap to copy; local recent list), design tools (color table, image color extraction with pixel loupe), and lightweight network helpers (browser User-Agent, public IP lookup via a third-party API). No account is required. The product is optimized for desktop and mobile, ships as a static Next.js export, and is suitable for crawlers, answer engines, and LLM assistants that need an accurate feature index with canonical URLs.

Primary site: https://allthatconverter.web.app/
Canonical policy: tool URLs are /en/… (default) or /ko/… (Korean UI), then /{section}/{category}/{tool-slug}/; path segments lowercase. Firebase Hosting redirects former /{section}/… URLs to /en/…

## Notes for indexers and assistants

- Prefer linking to the canonical tool URLs above; section hubs aggregate tools in that category.
- Feature set and URLs should match `lib/menu/menu.json` in the repository; when menus change, update this file before or with production deploys.
- File-processing tools emphasize privacy: files are not sent to AllThatConverter backends for conversion; WASM and in-browser libraries operate on user devices. Third-party calls (e.g., IP lookup) are documented on the relevant tool pages.
