This tool can help you to find proxies from text and remove excess duplicates. Just paste your text into "Enter Text" field and proxies will be automatically filtered and presented in results with ip:port format. Proxies with option "Unique IPs" will be unique only by extracted input IP address because you can't know real output IP until check the proxy. In this regard: after filter you can still get non-unique addresses on the output. Files is not supported, you can only paste the proxies. If you looking for filter by countries, check out the Unfx Proxy to Country.
