Slugify

The Slugify tool turns ordinary titles, headings and phrases into clean, URL-friendly slugs that are safe to use in web addresses, file names and identifiers. It strips out punctuation, converts spaces into a single separator, removes accents from letters, and produces a tidy lowercase string with no awkward characters that could break a link or look untidy in a browser bar.

It is made for bloggers and content editors creating readable post URLs, developers generating stable keys and route segments, and SEO specialists who want descriptive, keyword-rich addresses. Anyone who needs to convert a human title into a machine-friendly handle will get a consistent, predictable result without manually deleting symbols and replacing spaces by hand.

Everything runs locally in your web browser using JavaScript, with no server involved. You can paste a single title or a whole list of headings, one per line, and each is converted instantly. Because nothing is uploaded, even unpublished article titles, internal project names and confidential drafts stay completely private on your own device.

Features

• Converts any title or phrase into a clean slug by replacing spaces and punctuation with a single chosen separator.
• Removes accents and diacritics so letters like é and ñ become their plain ASCII equivalents for maximum compatibility.
• Lets you choose a hyphen or an underscore as the word separator to match your platform or naming convention.
• Optionally lowercases the entire slug, which is the most common and SEO-friendly style for clean web addresses.
• Collapses runs of separators and trims them from the start and end so you never get double or trailing dashes.
• Processes a whole list at once, converting each line into its own slug so you can batch many titles in one go.
• Strips emoji, symbols and other non-alphanumeric characters that would otherwise need percent-encoding in a URL.
• Runs entirely offline in your browser with no sign-up, no upload and no limit, keeping unpublished titles private.

How to use Slugify

1. Paste a title, heading or phrase into the input box, or enter a list of titles with one on each separate line.
2. Choose whether you want hyphens or underscores as the separator between words in the generated slug.
3. Decide whether to lowercase the slug, which is the usual choice for clean and consistent web addresses.
4. Read the slug or list of slugs that appears instantly in the output panel as you type or change options.
5. Check that the result reads clearly and contains the keywords you want before using it in a URL or file name.
6. Copy the slug to your clipboard or download the full list as a text file to use in your CMS or codebase.

Benefits

• Bloggers create readable, descriptive post URLs that look professional and help both readers and search engines.
• Developers generate stable, predictable identifiers and route segments from titles without writing a helper each time.
• SEO specialists craft keyword-rich slugs that improve click-through and make the topic of a page obvious in results.
• Content teams keep URL naming consistent across an entire site by running every title through the same converter.
• Documentation writers turn section headings into anchor-friendly fragment identifiers for in-page navigation links.
• Anyone handling unpublished titles benefits because the conversion is local and nothing is ever sent to a server.

A good slug is short, descriptive and stable. Search engines and readers both benefit when a URL clearly reflects the page topic, so it is usually best to keep the most important keywords and drop filler words if the slug grows too long. Because this tool processes each line separately, you can paste a list of planned article titles and generate a whole set of consistent slugs in one step.

Accent stripping matters for compatibility. While modern browsers can display accented characters in URLs, many systems, share links and analytics tools handle plain ASCII more reliably, so converting é to e and ü to u avoids percent-encoded addresses that look messy when copied. The separator choice is mostly convention: hyphens are standard for web URLs, while underscores are common for file names and some code identifiers.

All conversion happens locally in your browser, so your titles are never uploaded, logged or stored anywhere, keeping unpublished content private. Slugs are generated from the visible text only and do not check whether a URL already exists, so if you need guaranteed uniqueness you may still append a number or date in your own system after generating the base slug here.
