What is Robots.txt generator?

Robots.txt Generator — Write a valid robots.txt file in minutes, not hours. Add your crawl rules and sitemap URL, then copy the ready-to-upload file. Free.

This tool parses a simple line format (User-agent:, Allow:, Disallow: — case-insensitive, one directive per line, blank line starts a new group, # lines ignored) and emits standard robots.txt text: one User-agent group per block followed by an optional Sitemap: line. Paths not starting with "/" are corrected by prepending "/" and reported; non-ASCII paths are percent-encoded; an empty Disallow for an agent means "allow all" per the standard and is noted. Every rule in the output comes from your own input — nothing is invented. Correctness of the URLs themselves depends on the paths you enter.

Good to know

Whether a URL is actually blocked or allowed depends on the paths you enter — review them before publishing.
robots.txt is a crawling hint to search engines, not a security control — it does not keep private pages hidden from people.
An empty Disallow for an agent means "allow all" per the standard; the tool notes this rather than changing it.

How it works

This tool parses a simple line format (User-agent:, Allow:, Disallow: — case-insensitive, one directive per line, blank line starts a new group, # lines ignored) and emits standard robots.txt text: one User-agent group per block followed by an optional Sitemap: line. Paths not starting with "/" are corrected by prepending "/" and reported; non-ASCII paths are percent-encoded; an empty Disallow for an agent means "allow all" per the standard and is noted. Every rule in the output comes from your own input — nothing is invented. Correctness of the URLs themselves depends on the paths you enter.

Examples

Block admin, allow the rest

Two blocks of rules plus a Sitemap line in the output file.

Allow everything

An empty Disallow means crawlers may access everything — the tool notes this.

Auto-corrected path

"admin" is corrected to "/admin" and the correction is reported in Notes and corrections.
