01 / FILES
Conversion is local
Selected files are processed by browser code and workers on your device. Henka does not send file contents to a conversion server.
Privacy, in plain language
Your files stay in your browser.
Henka is designed to convert files on your device. There is no conversion upload endpoint in this app.
02 / PREFERENCES
Only interface choices are saved
Henka stores your language and theme preferences in your browser's local storage. Those preferences are not file contents.
03 / MEDIA TOOLS
Some tools load on first use
Audio and video conversion downloads the FFmpeg media engine in your browser when needed. This is application code, not an upload of your media.
04 / YOUR CONTROL
You choose the file and the download
The page keeps file data in memory while you work. Remove files or close the page when finished; downloaded results are saved by your browser.
