Tool Input and Local Processing
The selected file, entered text, calculated parameters, and generated password are processed by the current browser. The tool code does not upload this content to this site's server, and does not use cookies or localStorage to save tool input. This site will not restore your workspace after reloading or closing the page.
Clicking "Download" will generate a result file on your device; clicking "Copy" will write the result to your system clipboard. These files, clipboard, browser extensions, and device synchronization behavior are managed by your device and related software.
Server logs when accessing the page
Accessing this site requires communication between your browser and the server. Nginx records access time, IP address, request path, HTTP status, User-Agent, and Referer information attached to the request for troubleshooting and service maintenance. Please do not enter passwords or private information in the page address or query parameters.
The current logs are rotated daily, retaining 14 rotation records; the current logs and records that have not yet triggered rotation are counted separately. No external log analysis or log backups are configured. Server maintainers can read these logs but do not publicly display them or use them as verified unique visitor statistics.
Advertising, statistics and external links
Currently, this site does not load any advertising scripts, third-party analytics scripts, or remote fonts, nor does it generate advertising revenue through any tools. If advertising, statistics, or consent management are enabled in the future, this page will be updated accordingly.
External materials in the main text will only open after you actively click on the link, at which point the privacy policy of the respective website will apply. This site does not control the services provided by those websites.
