About Free Proxies

• What are free proxies?

  Free proxies are network services that allow users to access the internet through a proxy server. They can hide the user's IP address, providing a certain level of anonymity and privacy protection. Our website offers various types of free proxies, including HTTP, SOCKS4, SOCKS5, V2Ray, SSR, SS, and Mtproto.

• How do I use free proxies?

  To use free proxies, you need to configure the proxy server's IP address and port number in your browser or application. Here are the steps:

  1. Select a suitable type of free proxy on our website.
  2. Copy the proxy server's IP address and port number.
  3. Paste the IP address and port number into the corresponding input fields in your browser or application's proxy settings.
  4. Save the settings and reconnect to the internet to access the web through the proxy server.
• What is the stability and speed of free proxies?

  Since free proxies are usually shared, there may be some stability issues, such as unstable connections and slow speeds. The free proxies on our website have been screened and tested to provide relatively stable and fast proxy services. However, please note that the performance of free proxies may not be as good as paid proxies, and you should choose the appropriate proxy type according to your actual needs.

About Free Tools

• What is a Web Crawler?

  Web Crawler is a web scraping tool used to automatically retrieve and analyze web page content. It can help users quickly obtain a large amount of web data and is suitable for data collection and content analysis scenarios. When using a Web Crawler, please respect the website's copyright and privacy policies.

• How do I use Proxy Checker?

  Proxy Checker is a proxy testing tool used to check the availability and performance of proxy servers. You can input the proxy server's IP address and port number into Proxy Checker, and it will automatically test the proxy server's connection speed, stability, and other indicators, providing you with the corresponding test results. Using Proxy Checker can help you filter out high-quality proxy servers.

• What is the purpose of IP Checker?

  IP Checker is an IP address query tool used to detect your IP address information, including the IP address's geographical location, affiliated operator, network type, etc. With IP Checker, you can learn the details of your IP address or verify the IP address of the proxy server when using a proxy.

• How can Port Checker assist me?

  Port Checker is a port detection tool used to check whether the specified IP address's port is open. It can quickly check the port's open status, helping you troubleshoot network connection issues and configure firewall rules. For example, when using a proxy server, if the connection fails, you can use Port Checker to check whether the proxy server's port is open to determine the problem.

Other Common Questions

• How can I ensure the security of using proxies?

  When using proxies, security is an important consideration. Here are some suggestions:

  • Choose a reputable proxy provider to ensure the security and stability of the proxy server.
  • Use proxies with encrypted protocols (such as HTTPS, SOCKS5) to better protect the security of data transmission.
  • Regularly change proxy servers to reduce the risk of being tracked.
  • Avoid accessing sensitive or important websites (such as banks, payment platforms) through proxies to prevent potential security risks.
• How can I improve proxy usage efficiency?

  Improving proxy usage efficiency can be achieved through the following methods:

  • Choose the appropriate type of proxy according to actual needs. For example, use HTTP proxies for web browsing and SOCKS5 proxies for P2P downloads.
  • Reasonably configure the connection parameters of the proxy server, such as timeout and retry times, to optimize connection speed and stability.
  • Use proxy testing tools (such as Proxy Checker) to regularly check the performance of proxy servers and filter out high-quality proxies.
  • Avoid frequently switching proxy servers to maintain stability and improve proxy usage efficiency.
• What should I do if I encounter proxy connection issues?

  If you encounter proxy connection issues, you can try the following methods:

  • Check whether the proxy server's IP address and port number are correct and ensure that the configuration is error-free.
  • Use Port Checker to check whether the proxy server's port is open to rule out port issues.
  • Check whether the network connection is normal and ensure that the device can access the internet.
  • Try switching to other proxy servers to rule out problems with the current proxy server.
  • If the problem persists, you can contact our technical support team, and we will do our best to help you solve the problem.
