Proxy Format Converter
Convert proxy lists between common notations. Everything runs in your browser; the tool does not test proxy availability or connectivity.
1. Input proxies
Paste one proxy per line or import a TXT file. Proxy records may contain credentials or no authentication, and IPv6 must use [square brackets].
2. Conversion settings
Choose an antidetect browser and a recommended format or override the output format manually. For ambiguous records, set the input format.
3. Preview & export
Review output and errors. For authenticated formats, masked passwords remain present in copied and downloaded exports.
4. Guide & FAQ
The converter changes text formats but does not verify availability or actual proxy type.
Which formats are supported?
HOST:PORT, HOST:PORT:USER:PASS, USER:PASS@HOST:PORT, USER:PASS:HOST:PORT, HOST:PORT|USER|PASS and URL forms using http, https, socks4, socks5 or socks5h. CSV and JSON exports are also available.
Does it support IPv6 proxies?
Yes, with brackets: [2001:db8::2]:1080. Unbracketed IPv6 is rejected to avoid confusing colons in addresses with separators.
Does it test whether proxies work?
No. The tool only validates local syntax and converts formats. It never connects to the supplied proxies.
What if a record is ambiguous?
Select the input format manually. Auto-detection intentionally does not guess when numeric fields could be interpreted in multiple ways.
How are credentials handled?
Compatible formats preserve them. URI escaping protects special characters in URLs. A record is rejected if the destination format cannot represent it safely. HOST:PORT intentionally removes authentication.
Is all processing local?
The converter’s own code sends no network requests. Hosting platforms and third-party scripts may have their own data handling and require separate review.
What are the limits?
Up to 10,000 entries, 2 MB input text/file and 4 MB output; processing runs in your browser.
What does the antidetect-browser selection do?
Where official documentation confirms a proxy paste format, the tool recommends that format. For other browsers it only suggests a generic notation, not a certified import file. You can always choose the output format manually.
