About these tools
Are my files uploaded?
The tools work locally and do not send files, filenames, text or results to a server. Loading these pages still requests ordinary static website resources.
Can I use another language?
English, simplified Chinese, traditional Chinese and Japanese have fixed page addresses. A language switch keeps the same tool or content where that translation is available.
Do I need an account?
No. Open a tool and use it directly. You can choose whether to save a manual language preference; optional services and their storage are explained on the privacy page.
