Before converting, check your BIN file:
A PAC file contains a JavaScript function like:
function FindProxyForURL(url, host)
if (shExpMatch(host, "*.example.com")) return "PROXY proxy.local:8080";
return "DIRECT";
You cannot directly extract this from a random firmware .bin unless the firmware contains proxy rules.
1. Locate or Download PAC Creator
If you have the SpreadTrum USB Drivers and Research Tool installed on your PC, look for the PACCreator application. Alternatively, standalone tools like Uni-Android Tool (UAT) or Infinity Box CM2 often have built-in PAC creators. how to convert bin file to pac file hot
2. Create a New Project
3. Configure Firmware Info The tool will ask for basic details about the device. You can usually fill this with generic info, but for the firmware to work, the Partition Table is crucial.
4. Add the .BIN Files
5. Build the PAC

Avoid "BIN to PAC Converter.exe" from random blogs—100% of them are malware as of 2026. Before converting, check your BIN file:
Assume your extracted config has lines like:
proxy 192.168.1.100 port 8080 for *.google.com
proxy 192.168.1.100 port 8080 for *.facebook.com
direct for all others
Turn that into a PAC file:
function FindProxyForURL(url, host)
if (shExpMatch(host, "*.google.com")) return "PROXY 192.168.1.100:8080";
if (shExpMatch(host, "*.facebook.com")) return "PROXY 192.168.1.100:8080";
return "DIRECT";
Save it as proxy.pac.
