Why clean URLs matter

A URL is the smallest piece of copy you publish, and it appears everywhere: search results, browser bars, chat messages, printed citations. Readable slugs earn more clicks in search results, survive being pasted into plain text, and tell both people and crawlers what a page is about before it loads.

Private by architecture

Everything here — slugifying, parsing, encoding, cleaning — runs as client-side code in your browser. There is no backend processing your input, no logging of what you paste, and campaign URLs or unreleased titles never cross the network.

Frequently asked questions

What is slug.tools?
slug.tools is a free set of eight browser-based URL utilities: a URL slug generator, a bulk slug generator, a UTM campaign builder, a URL parser, a tracking-parameter cleaner, a URL encoder/decoder, a Base64URL encoder, and a SERP and social preview tool. No sign-up is required.
Are the tools free?
Yes. Every tool is free to use with no account, no usage limits, and no paywalled features.
Is my data sent to a server?
No. All processing happens in your browser with client-side JavaScript. The titles, URLs, and text you paste are never uploaded, stored, or logged. The site uses Google Analytics to count page views, but it does not record what you type into the tools.
What is the best format for a URL slug?
Lowercase ASCII words separated by hyphens, about three to five words and under 60 characters, matching the main search phrase for the page — for example, /url-slug-best-practices. Avoid underscores, spaces, special characters, and dates that will go stale.
Who builds slug.tools?
slug.tools is built and maintained by Abdessamad Bettal, an independent web developer. Every guide on the blog is written alongside the tool it explains.
