Common questions
Do I need an account?
No. Free tools finish with a download and never ask for an email address.
Where is my file processed?
This tool runs inside your browser. Renderbound never receives the source file.
How long are server files kept?
Temporary inputs and outputs are deleted after download where possible, with a 24-hour lifecycle rule as the hard backstop.
