This tool will help you find proxies from text and remove unnecessary duplicates. Just paste your text (you can also select multiple files, they will be combined) and the proxies will be automatically filtered and presented in the results in ip:port format. Proxies with the "Unique IP" option will be unique only by the retrieved input IP, because you cannot know the real output IP until you check the proxy. Related to this: after filtering, you may still get non-unique addresses in the output. Files are not supported, you can only insert proxies. If you need a country filter, check out Unfx Proxy to Country.
