Proxy Format Converter

Why change the format

A proxy line has four parts: host, port, username and password. Programs expect them in different orders and with different separators. If the format is wrong, the program either rejects the line or mixes the parts up — and the proxy "does not work" even though nothing is wrong with it.

Which format to choose

• host:port:username:password — the most common one for antidetect browsers and many scrapers.
• username:password@host:port — the usual one for scripts and the command line.
• protocol://username:password@host:port — the full address; suitable where the protocol has to be stated explicitly.
• host:port — without credentials; for programs that work with an IP whitelist.

If you are not sure, look at the example in the proxy input field in the program itself or in its guide — the guides section gives the format for each one.

Common mistakes

Special characters in the password. In the full-address format the characters @ and : in the password are encoded, otherwise the address is parsed incorrectly. The converter does this for you.

The line is "not recognized". Check that it has no spaces inside and that the port is a number from 1 to 65535.

After converting, test one line in the proxy checker before loading the whole list.
