## Product principles

- No sign-up is required for current basic tools.
- TinyTools is local-first: most file and text processing runs locally in the user's browser.
- The product is mobile-first and supports desktop browsers and mobile/WeChat browser usage.
- The interface automatically follows a supported browser language unless the user chooses another language.
- Search covers both individual tools and guided quick tasks, including names and keywords across Chinese, English and the selected UI language.
- TinyTools focuses on lightweight utilities. Video downloading/transcoding and other heavy media workflows are outside this product's scope.
- Tool results can often continue into another compatible tool without re-uploading.
