Proxy Formatter
Convert proxy lists between IP:PORT, USER:PASS@IP:PORT, and other formats. Free, instant, runs in your browser.
100% client-side
Your list never leaves the browser.
Instant
Converts as you type, no waiting.
Four formats
Auto-detected, no manual sorting.
Proxy Formatter
Paste a list of proxies, one per line, and convert them between formats.
Converted proxies will appear here.
Runs entirely in your browser — nothing you paste is ever uploaded or stored.
Supported Formats
Auto-detect reads each line and converts mixed lists without any manual sorting.
IP:PORT No authentication.
USER:PASS@IP:PORT The format most scrapers and HTTP clients expect.
IP:PORT:USER:PASS Common with older tools and some datacenter proxies .
IP:PORT@USER:PASS Used by some anti-detect browsers and proxy managers.
How It Works
Paste your proxy list, one per line.
Select input format, or leave it on Auto-detect.
Select the output format you need.
Copy or download the converted list.
Why Use This
Fixes silent connection failures.
A scraper expecting user:pass@ip:port will error out on a list written as ip:port:user:pass, even when every credential is valid. Wrong format, not a bad proxy, is the most common reason a working list stops connecting.
No size limit.
Convert a handful of test proxies or a list of several thousand in one pass.
Nothing leaves your browser.
Formatting runs client-side. Credentials are never sent to a server or logged.
Built for switching tools.
Moving proxies between a new provider, a scraper, or an anti-detect browser almost always means reformatting, since none of them standardize on the same output.
Works With Any Proxy List
This tool isn't tied to Proxyon proxies. It formats any list, from any provider. If you're setting up fresh, residential proxies start from $2.25/GB and datacenter proxies start from $1.50/IP, both pay-as-you-go with no subscription. Full breakdown on the pricing page.
Frequently Asked Questions
Everything else you might want to know about the formatter.
Does the formatter test if my proxies are working?
No. This only rewrites format, it doesn't check whether a proxy is reachable. Use our IPv6 Tester (in the Tools menu) to check connectivity.
Is there a limit on how many proxies I can convert?
No. Convert a handful of proxies or a list of several thousand in one pass — there's no size limit.
Are my proxy credentials stored anywhere?
No. Formatting happens locally in your browser. Nothing you paste is uploaded, logged, or stored.
What if my list mixes more than one format?
Leave the input format on Auto-detect — it reads each line independently and converts a mixed list without any manual sorting.
Need proxies to go with it?
Residential, datacenter, and IPv6 — pay as you go, no subscriptions.
