Convert Apache, Nginx and IIS web.config Rewrite Rules in Seconds
Migrating a site to or from Windows/IIS hosting usually means manually rewriting URL rules into a completely different format: IIS's URL Rewrite Module uses XML instead of the line-based directives found in Apache's .htaccess or Nginx's nginx.conf.
Our free web.config converter automatically translates common
RewriteRule,
RewriteCond, and Redirect directives (or Nginx's rewrite,
return, and location blocks) into IIS's
<system.webServer><rewrite> rule format, and back again.
As with any cross-platform conversion, IIS uses .NET regular expressions rather than PCRE, so review generated rules before deploying to production — especially anything involving complex regex lookarounds or server-variable conditions.

Web Server Comparison
Apache vs Nginx vs IIS
A quick comparison of the three most common web server platforms and their rewrite/redirect configuration approach.
| Feature | Apache HTTP Server | Nginx | IIS (Windows) |

| Rewrite Engine | mod_rewrite | Built-in rewrite module | URL Rewrite Module |
| Regex Flavor | PCRE | PCRE | .NET Regex |
| Per-directory Overrides | Native (.htaccess) | Not supported | Native (web.config per folder) |
| Platform | Cross-platform | Cross-platform | Windows Server |
| GUI Management | Limited | Limited | IIS Manager |
| Best For | PHP apps, WordPress, shared hosting | High-traffic sites, reverse proxy, CDN | ASP.NET apps, Windows-based hosting |

FAQsweb.config Converter
Can this tool convert web.config to .htaccess and back?
Why does IIS use XML instead of plain text rules?
IIS's URL Rewrite Module stores rules inside the web.config file, which follows .NET's standard XML configuration format used across IIS and ASP.NET.
Will every rule convert perfectly?
No. IIS uses .NET regular expressions rather than PCRE, and complex RewriteCond logic or nested Nginx location blocks may need manual adjustment after conversion.
Is my configuration uploaded anywhere?
No. All conversion happens inside your browser using JavaScript. Your rules are never transmitted to our servers.
