A double slash URL checker is a free online tool that finds accidental double slashes in link paths, like example.com//products//shoes, and fixes them to single slashes. The https:// protocol slashes are always preserved. Paste a batch of URLs, review what changed, and copy or download the corrected links.
How do I fix double slashes in a URL?
Short answer: Paste your URLs, one per line, and press Scan and fix. The tool collapses every run of two or more slashes in the path and query down to one, while leaving the https:// protocol separator exactly as it is. Each link shows its before and after, and you can copy all fixed URLs or download them as a text file.
Links with no double slashes are reported as already clean, so you can verify a whole sitemap export in one pass.
Why do double slashes appear in URLs?
Short answer: They usually come from joining a base URL that ends with / to a path that starts with /, from CMS templates that add slashes conditionally, or from redirects that stack. Most servers tolerate them, but they create duplicate-content risk for SEO when both /page and //page get indexed as separate URLs.
Fixing them at the source (your templates or link builder) stops new ones; this tool repairs the links you already have.
Does fixing double slashes change where the link goes?
Short answer: Almost never: web servers treat /products//shoes and /products/shoes as the same resource. The fix only normalizes the path, keeping the protocol, host, query parameters, and hash fragment fully intact. Relative paths without a protocol are handled the same way, and the original link is always shown for comparison.
After fixing, set up a redirect or canonical tag from the double-slash version if it was already indexed, so search engines consolidate the signals.
Frequently asked questions
Is this double slash checker free?
Yes. Scan unlimited URLs with no account and no limits. It runs entirely in your browser.
Will it break the https:// in my URLs?
No. The protocol separator is detected first and excluded from fixing. Only slashes after the host are collapsed.
Does it fix triple or longer slash runs?
Yes. Any run of two or more slashes in the path or query becomes a single slash.
Can it check URLs without https://?
Yes. Relative paths like /blog//post are fixed the same way; the tool only skips the protocol pattern when one is present.
Are my URLs uploaded anywhere?
No. Scanning and fixing happen locally in your browser.
