Process individual proxies or bulk lists. Invalid rows are identified by line number while valid rows continue to convert.
Local converter
HTTP, SOCKS4 and SOCKS5 proxy format converter
Paste a proxy list, select the protocol and output format. Conversion runs locally in your browser, so addresses, usernames, and passwords are not sent to the server.
Conversion runs only in your browser. Entered addresses, usernames, and passwords are not sent to the server.
Five output formats
Generate HOST:PORT:USERNAME:PASSWORD, USERNAME:PASSWORD@HOST:PORT, protocol URLs, JSON, or CSV.
Credentials stay in the browser
The converter does not make a network request with entered data and does not test the proxies themselves. Use the separate checker for that.
Practical guides
From a successful check to a correct setup
Use these concise guides to choose a protocol, prepare credentials, and handle retries without unnecessary load.
Common questions
Which proxy protocols are supported?
HTTP, HTTPS, SOCKS4, and SOCKS5. A protocol already present in a URL is preserved; bare lines use the selected protocol.
Can I convert proxies without authentication?
Yes. HOST:PORT is supported. Authentication fields remain empty in JSON and CSV output.
Does the converter test whether proxies work?
No. It changes the credential representation only. Use the proxy checker to test connectivity, authentication, and exit IP.
Can it turn a SOCKS4 or SOCKS5 proxy into HTTP?
No. Changing text or a URL scheme does not change the server's network protocol. The converter only rearranges fields and preserves the real protocol; HTTP requires an endpoint that actually supports HTTP.
