Proxy Formatter

A proxy formatter is a tool that converts proxy lists between different formats. When working with proxies from multiple providers, you often receive them in various formats like IP:Port, User:Pass@IP:Port, or JSON. This tool standardizes your proxy lists into a single format compatible with your scraping tools, automation scripts, or browser extensions. It saves hours of manual formatting and reduces errors in your proxy configuration.

Yes, this proxy formatter is 100% free with no usage limits, no registration required, and no hidden costs. You can convert unlimited proxies as many times as you need. We built this tool to help developers and data professionals work more efficiently with proxy lists without paying for expensive software subscriptions.

Your proxy data is completely secure. All processing happens directly in your browser using JavaScript. Your proxy lists are never sent to any server, never stored, and never logged. The tool works entirely offline once loaded. This means your sensitive proxy credentials and IP addresses remain private and under your control at all times.

There is no hard limit on the number of proxies you can format. The tool is optimized to handle thousands of proxies efficiently. For very large lists (10,000+ proxies), processing may take a few seconds depending on your browser and device. We recommend processing in batches of 5,000 for the best performance on older devices.

The tool supports all common proxy formats including IP:Port (basic format), User:Pass@IP:Port (authenticated proxies), User:Pass:IP:Port (colon-separated auth), IP:Port:User:Pass (IP-first format), Protocol://IP:Port (with HTTP/HTTPS/SOCKS prefix), full proxy URLs, CSV format, and JSON objects. The auto-detect feature identifies your format automatically, or you can manually select the input format.

You can export your proxy list to multiple formats: IP:Port for simple use cases, authenticated formats with credentials, full URL format for browsers and HTTP clients, cURL commands for terminal use, JSON arrays for API integration, and CSV for spreadsheet applications. Each format is optimized for specific use cases like web scraping, browser automation, or API development.

If auto-detection fails, you can manually select the input format from the dropdown menu. The tool supports mixed formats in a single list. If your format still is not recognized, try one proxy at a time to identify the issue. Common problems include extra whitespace, special characters in passwords, or non-standard delimiters. Contact us if you need support for a custom format.

Yes, you can set default username and password values in the configuration section. These credentials will be applied to any proxy that does not already have authentication. This is useful when you have a list of IP:Port proxies that all share the same login credentials from your proxy provider.

Yes, enable the "Remove Duplicates" checkbox to automatically filter out duplicate proxies based on their IP address and port. This feature is helpful when merging proxy lists from multiple sources. The tool will show you how many duplicates were removed after processing.

Yes, the tool fully supports SOCKS4 and SOCKS5 proxies. You can set the default protocol in the configuration or use input formats that include the protocol prefix (like socks5://ip:port). The output will preserve or apply the correct protocol based on your settings, making it compatible with applications that require specific proxy types.
