htaccess to Nginx

How htaccess to Nginx works

Translate Apache RewriteRule lines into Nginx rewrite directives. Handles common 301 and 302 patterns; anything unusual is commented out. Everything happens inside this page: the tool reads your input, runs the calculation or conversion locally, and hands the result back to you. Nothing is transmitted, because there is no backend to transmit it to.

That design choice is deliberate. Most free tool sites upload your files to a server, process them there, and quietly keep a copy. Toolcin cannot do that — the site is a set of static files. If your connection dropped the moment the page finished loading, every tool would still work.

What translates cleanly

The common redirect patterns map directly: RewriteRule with R=301 becomes a permanent nginx rewrite, R=302 a temporary one, and a plain internal rewrite becomes a rewrite without a redirect flag.

Each line becomes one nginx directive, so a rule set of ten redirects produces ten lines rather than one clever block.

What gets commented out

Anything the converter cannot map confidently is emitted as a comment rather than a guess. Conditions (RewriteCond), variables, and rules using server-specific modules usually fall into this category — a wrong rewrite rule is worse than an obvious TODO.

Apache's per-directory context and nginx's server/location blocks are structurally different, so a direct line-by-line translation is not always possible.

Testing the result

Run nginx -t before reloading, and test each rule with a query string attached. A rewrite that drops the query string silently breaks campaign tracking and looks like an analytics failure rather than a config one.

Good to know

• Works offline once loaded, including on flights and in locked-down networks.
• No file size limit beyond your device's own memory.
• Free to use, with no account and no usage counter.
• Results are produced locally, so they are not logged or shared with anyone.
