Free Proxy FAQ
What proxy formats are supported?
Our tool supports all common proxy formats including IP:Port, Username:Password@IP:Port, Protocol://IP:Port, full URLs, CSV, JSON, and more. The auto-detect feature can identify mixed formats automatically.
Can I convert between any formats?
Yes! You can convert from any supported input format to any supported output format. For example, convert from CSV to JSON, or from full URLs to simple IP:Port format.
How does auto-detection work?
Auto-detection analyzes each line of your input and tries to identify the format automatically. It works with mixed formats in the same input, making it perfect for cleaning up proxy lists from multiple sources.
What happens to authentication credentials?
If your input contains usernames and passwords, they'll be preserved in the output format (if the output format supports them). You can also add default credentials for proxies that don't have them.
Is there a limit to how many proxies I can format?
This is a client-side tool, so the only limit is your browser's memory. You can typically format thousands of proxies without any issues.
Can I download the formatted results?
Yes! You can copy the results to your clipboard or download them as a file. The file format (TXT, JSON, CSV) is automatically chosen based on your output format selection.
