URL Cleaner

The URL Cleaner normalises a list of links by stripping the cosmetic and redundant parts that make otherwise identical URLs look different. It can remove fragments, drop trailing slashes, delete default ports, collapse duplicate slashes and lowercase the host, turning a messy set of links into a consistent, canonical list.

It is designed for SEO teams deduplicating URLs, developers preparing canonical links, and anyone comparing lists where trivial differences cause false mismatches. A URL with a trailing slash, an explicit port 443 or an uppercase host points to the same place as its tidy equivalent, yet naive comparisons treat them as distinct; cleaning them first makes deduplication and matching reliable.

Everything runs locally in your browser using JavaScript and the standard URL engine, so normalisation matches how browsers understand addresses. Nothing you paste is uploaded or stored, which means internal and staging URLs can be cleaned in bulk without leaving your device.

Features

• Removes the fragment after the hash, which never affects which page a URL requests.
• Strips trailing slashes from paths so /page and /page/ are treated identically.
• Deletes default ports, dropping :80 from http and :443 from https addresses.
• Collapses duplicate slashes in the path so //a///b becomes a clean /a/b.
• Lowercases the host, since domain names are case-insensitive by specification.
• Each transformation is an independent toggle so you clean exactly what you want.
• Reports how many URLs changed and exports the cleaned list to a text file.

How to use URL Cleaner

1. Paste your list of URLs into the input box, one per line.
2. Enable the transformations you want, such as stripping fragments and trailing slashes.
3. Leave options off when you need to preserve, for example, an in-page fragment.
4. Read the cleaned URLs in the output, one per line, ready to copy or export.
5. Check the stats to see how many URLs were actually changed by the cleanup.
6. Copy the cleaned list or download it as a text file for deduplication or import.

Benefits

• SEO teams produce canonical URLs so duplicate variants do not split ranking signals.
• Developers normalise links before storing or comparing them to avoid false mismatches.
• Analysts deduplicate URL lists reliably once cosmetic differences are removed.
• Teams tidy scraped or exported links into a consistent, predictable format.
• Anyone comparing two URL lists gets accurate matches after normalising both.
• Because cleaning is local, internal and staging URLs never leave your device.

URL normalisation is the process of transforming URLs that are technically different but functionally equivalent into a single canonical form. The specification says the scheme and host are case-insensitive, default ports carry no meaning, and a fragment is only a client-side pointer within a page. Applying these rules turns a jumble of near-identical links into one clean representation, which is the foundation of accurate deduplication.

Trailing slashes and duplicate slashes are the most common source of accidental duplicates. Depending on server configuration, /page and /page/ may or may not resolve to the same content, and stray double slashes often creep in when paths are concatenated in code. Cleaning them gives you a consistent list, though you should confirm your server treats the trimmed forms the same way before using them as canonical.

All cleaning runs in your browser with JavaScript using the same URL engine browsers rely on, so nothing you paste is transmitted or stored. Because each transformation is a separate toggle, you stay in control; if a particular URL genuinely needs its fragment or trailing slash, simply leave that option off.
