About this tool
Paste or upload the list of old URLs and the list of new URLs. The mapper matches them by exact path, then by page name, then by similarity of the words in the path, gives each match a confidence score and flags the uncertain ones for human review. Export the rules for Apache (.htaccess), Nginx, Cloudflare _redirects or as a CSV. Always review matches below 80% before going live. Your files are read in your browser and never uploaded.
Website Migration Redirect Mapper is part of ToolStack Hub's SEO & Marketing Tools. It runs entirely in your browser, which keeps your data private and makes results instant. There is nothing to install, no account to create and no usage limit.
Frequently asked questions
How are old and new pages matched?
First by identical path (ignoring extensions like .html and trailing slashes), then by the page name at the end of the path, then by how many words the paths share. Each gets a confidence score.
Should I trust the matches?
Treat confident exact matches as reliable and review everything else. A wrong redirect can hurt users and search rankings more than a missing one.
Is the Website Migration Redirect Mapper free?
Yes. Website Migration Redirect Mapper is completely free with no sign-up, limits or watermarks.
Is my data private when I use the Website Migration Redirect Mapper?
