Proxy PAC to Data URL
Paste or type your proxy auto-configuration (PAC) script, then convert it to a Base64 data URL with the PAC MIME type.
Conversion stays in your browser. The script is encoded as UTF-8 without being executed or validated.
The result starts with data:application/x-javascript-config;base64, as described in the Server Fault answer. Copy the complete result into your automatic proxy configuration URL field.
