Why “runs in your browser” matters

Most online converters upload your files to a remote server, process them there, and send them back. Your photos, PDFs, and data pass through infrastructure you know nothing about — and often get stored for days.

Every tool on FileConvertiz runs the conversion locally using JavaScript. Your files never leave your device. There is no server that could receive them, because the processing never goes anywhere.

Close the tab and everything is gone from memory. No account, no data retention, no privacy policy loopholes to worry about.
