Text to Slug Converter Examples

The Text to Slug Converter transforms text into URL-friendly slugs by lowercasing, removing special characters, and replacing spaces with hyphens. Below are practical examples for blog posts, products, and multilingual content.

Basic Slug Generation

// Input → Output
"Hello World"                    → "hello-world"
"My Blog Post Title"             → "my-blog-post-title"
"10 Tips for Better Code"        → "10-tips-for-better-code"
"What is REST API?"              → "what-is-rest-api"
"Node.js vs Python"              → "nodejs-vs-python"
"C++ Programming Guide"          → "c-programming-guide"
"100% Free Tools"                → "100-free-tools"

Transformation Steps

// Input: "My Top 10 JavaScript Tips for 2024!"

// Step 1: Lowercase
"my top 10 javascript tips for 2024!"

// Step 2: Remove/replace special characters
"my top 10 javascript tips for 2024"

// Step 3: Replace spaces with hyphens
"my-top-10-javascript-tips-for-2024"

// Step 4: Collapse multiple hyphens
"my-top-10-javascript-tips-for-2024"  (no change needed)

// Step 5: Trim leading/trailing hyphens
"my-top-10-javascript-tips-for-2024"  (no change needed)

// Final slug: "my-top-10-javascript-tips-for-2024"

Diacritic Handling (Accented Characters)

// Accented characters → ASCII equivalents
"Café au Lait"           → "cafe-au-lait"
"Résumé Writing Tips"    → "resume-writing-tips"
"Über die Straße"        → "uber-die-strase"
"Señor García"           → "senor-garcia"
"Naïve Approach"         → "naive-approach"
"Ångström Units"         → "angstrom-units"
"Ñoño"                   → "nono"
"Üniversität"            → "universitat"

Special Character Handling

// Ampersand → "and"
"Salt & Pepper"          → "salt-and-pepper"
"Terms & Conditions"     → "terms-and-conditions"

// At sign → "at"
"Email @ Work"           → "email-at-work"

// Punctuation removed
"Hello, World!"          → "hello-world"
"What's New?"            → "whats-new"
"It's a Test..."         → "its-a-test"

// Slashes removed or replaced
"HTML/CSS Guide"         → "html-css-guide"
"2024/01/15"             → "2024-01-15"

// Multiple spaces/hyphens collapsed
"Hello   World"          → "hello-world"
"Hello---World"          → "hello-world"

Hyphen vs Underscore Separator

// Hyphens (recommended for URLs — Google SEO preference)
"my blog post"           → "my-blog-post"

// Underscores (for file names and database identifiers)
"my blog post"           → "my_blog_post"

// Google treats hyphens as word separators in URLs
// "my-blog-post" → words: my, blog, post (good for SEO)
// "my_blog_post" → treated as one word: myblogpost (worse for SEO)

Maximum Length Truncation

// Input (very long title):
"The Complete Guide to Building Scalable Microservices with Docker and Kubernetes in 2024"

// Without limit:
"the-complete-guide-to-building-scalable-microservices-with-docker-and-kubernetes-in-2024"
// Length: 88 characters

// With max length 60 (truncate at word boundary):
"the-complete-guide-to-building-scalable-microservices-with"
// Length: 58 characters (truncated at last complete word)

Blog Post URL Examples

// Blog post titles → URL slugs
"Getting Started with React Hooks"
→ /blog/getting-started-with-react-hooks

→ /blog/10-best-practices-for-rest-api-design

JavaScript Slug Generation

function toSlug(text) {
  return text
    .normalize('NFKD')                    // decompose accented chars
    .replace(/[\u0300-\u036f]/g, '')      // remove combining marks
    .toLowerCase()
    .trim()
    .replace(/[^\w\s-]/g, '')             // remove special chars
    .replace(/[\s_-]+/g, '-')            // spaces/underscores → hyphens
    .replace(/^-+|-+$/g, '');            // trim leading/trailing hyphens
}

toSlug("Hello World!")              // "hello-world"
toSlug("Café au Lait")              // "cafe-au-lait"
toSlug("My Top 10 Tips for 2024")   // "my-top-10-tips-for-2024"
toSlug("  Multiple   Spaces  ")     // "multiple-spaces"

Python Slug Generation

import unicodedata
import re

def to_slug(text):
    # Normalize and remove diacritics
    text = unicodedata.normalize('NFKD', text)
    text = ''.join(c for c in text if not unicodedata.combining(c))
    # Lowercase and clean
    text = text.lower().strip()
    text = re.sub(r'[^\w\s-]', '', text)
    text = re.sub(r'[\s_-]+', '-', text)
    text = text.strip('-')
    return text

to_slug("Hello World!")           # "hello-world"
to_slug("Café au Lait")           # "cafe-au-lait"
to_slug("My Top 10 Tips")         # "my-top-10-tips"

SEO Best Practices for Slugs

• Use hyphens as word separators (not underscores)
• Keep slugs short and descriptive (3–5 words ideal)
• Include the primary keyword in the slug
• Remove stop words (a, the, and, of) for shorter slugs
• Use lowercase only — avoid mixed case
• Avoid special characters and percent-encoding
• Keep slugs under 60 characters for clean URLs
• Never change a slug after publishing — it breaks existing links

Enter your text in the slug converter and get a clean, SEO-friendly URL slug ready to use in your application.
