4.5 / 5Proxy formatter
Convert proxy lists between every common layout - host:port, user:pass@host:port, full URLs and ready-made snippets. Deduplicate, swap credentials, force a protocol, all in your browser.
Formatter
Convert any proxy list into the format you need
Paste a list in any common layout. Detection runs per line, so mixed lists are fine. Everything happens in your browser - credentials never leave this page.
Smart detection reads each line on its own.
Custom template supports {scheme} {host} {port} {user} {pass}.

Supported formats
Every layout providers actually ship
There is no standard for proxy list files, so the same pool arrives in a different shape from every vendor. These are the layouts the parser understands on both sides of the conversion.
| Format | Example | Typical use |
|---|---|---|
| host:port | 203.0.113.10:8080 | Open proxies, IP whitelisted pools |
| host:port:user:pass | 203.0.113.10:8080:alice:s3cret | Proxy managers and rotator imports |
| user:pass:host:port | alice:s3cret:203.0.113.10:8080 | Common export from residential vendors |
| user:pass@host:port | alice:[email protected]:8080 | HTTP clients and most scraping libraries |
| host:port@user:pass | 203.0.113.10:8080@alice:s3cret | Legacy panels and some datacenter vendors |
| scheme://user:pass@host:port | http://alice:[email protected]:8080 | curl, requests, axios, any URL based client |
How it works
Four steps from messy export to usable list
Paste the list
Drop in whatever your provider gave you. Detection reads each line separately, so exports that mix authenticated and open proxies parse in one pass.
Pick the target format
Plain layouts for scrapers and bots, a full URL for HTTP clients, snippets for curl, Python and Node, or a custom template when a tool expects something unusual.
Clean it up
Remove duplicates, swap credentials, force a protocol, sort by host or port, cap the number of lines and add a prefix or suffix per row.
Copy or download
Take the result to the clipboard or save it as a .txt file that is ready to feed into your scraper, proxy manager or browser profile.
Where it helps
Formatting is the boring part of every proxy workflow
A pool is only as usable as the file it arrives in. These are the conversions that come up again and again.
Scrapers and crawlers
Most frameworks expect a single proxy URL per request. Converting once up front avoids per-request string building and the bugs that come with it.
Browser automation
Puppeteer, Playwright and antidetect browsers usually take host:port plus separate credentials, so stripping or splitting the auth part is the common step.
Proxy managers
Rotators and load balancers tend to import host:port:user:pass. Deduplicating by endpoint first keeps the pool honest and the stats readable.
Team handover
Replacing the username and password on an entire list is the quickest way to move a pool to a new sub-user without touching the endpoints.
FAQ
Questions about proxy formats
What proxy formats can the formatter read?
It reads host:port, host:port:user:pass, user:pass:host:port, user:pass@host:port, host:port@user:pass and full proxy URLs such as http://user:pass@host:port or socks5://host:port. Lines separated by spaces, tabs, commas, semicolons or pipes are normalised before parsing, and detection runs per line so a mixed list works without cleanup.
Are my proxies or credentials uploaded anywhere?
No. Parsing and formatting run entirely in your browser with client-side JavaScript. Nothing is sent to a server, logged or stored, which matters because a proxy list with credentials is effectively a password.
How do I change the username or password on a whole list?
Type the new username or password into the credentials fields. Every parsed line is rewritten with those values, which is the fastest way to rotate a shared login or move a list between sub-users. Leave a field empty to keep the original value.
How does duplicate removal work?
Two modes: remove duplicate host:port pairs, which catches the same endpoint listed with different credentials, or remove identical output lines, which only drops exact copies. The counter shows how many lines were discarded.
Which format should I use for curl, Python or Node?
curl and most HTTP clients want a full URL such as http://user:pass@host:port. The formatter ships ready-made outputs for a curl command, a Python requests proxies dictionary and a Node proxy string, plus a custom template with {scheme}, {host}, {port}, {user} and {pass} placeholders for anything else.
Does the formatter validate that proxies work?
No. It validates structure - hostname shape and a port between 1 and 65535 - and reports the lines it could not parse with a reason. Checking whether an endpoint is alive requires sending traffic through it, which a browser tool cannot do reliably.
Need proxies that are worth formatting?
Datacenter, residential and mobile pools with sticky sessions, city-level targeting and pay-as-you-go pricing.
