Files stay local
The file you select is read by browser code on your device. It is not uploaded to LocalConvert for conversion.
What the network receives
Your browser still downloads the website and the converter modules it needs. Those requests do not need to contain the contents of your file.
Temporary by default
Working data remains in browser memory or temporary local storage and can be cleared by closing or resetting the tool.
Measured without reading files
If basic site analytics are used, they must describe page activity—not file contents, extracted text, or generated output.
