What is Slug / URL Generator and Encoder/Decoder

Slug / URL Generator and Encoder/Decoder turns messy text and complex links into clean, shareable formats in seconds. Ever pasted a title with accents and symbols and ended up with a broken link? The free Slug / URL Generator and Encoder/Decoder by FlexiTools.io makes it simple: paste text or a URL, choose your slug options, and generate results you can copy or export. In the next 60 seconds, you can create neat slugs, encode or decode a URL, and even join a slug to a base URL.

How to Use Our Slug / URL Generator and Encoder/Decoder

  1. Paste your input
  • Enter text or a URL in the Text or URL box. Use Copy input if you need to reuse it, or Clear to reset.
  1. Pick your slug options
  • Choose Lowercase, Remove diacritics (accents), and your Delimiter (hyphen or underscore). Add a Base URL if you want a full path with your new slug.
  1. Generate results
  • Click Generate. You’ll see Preferred slug (based on your settings), plus presets like kebab-case, snake_case, camelCase, and PascalCase. You’ll also get URL encoded and URL decoded values, and a Joined URL if you provided a Base URL.
  1. Copy or export
  • Click Copy on any line, or Copy all to grab everything at once. Click Download CSV to export all labels and values for your records or teammates.

A Deeper Look at Slugs, URLs, and Encoding

What is a slug and why it matters

A slug is the readable part of a URL path that identifies a page. It often mirrors a title but strips punctuation, spaces, and special characters. A good slug is short, descriptive, and easy to type. For example, “10 tips for café owners” might become “10-tips-for-cafe-owners”. Clear slugs help users trust and remember links, and they reduce mistakes in emails or docs.

Our tool turns your text into multiple styles at once:

  • Preferred slug - follows your options for lowercase, delimiter, and diacritics removal.
  • kebab-case - words with hyphens.
  • snake_case - words with underscores.
  • camelCase and PascalCase - helpful for IDs or code-like contexts.

Why multiple styles? Teams use different conventions - marketing tends to use hyphens, while some systems prefer underscores or camel case. Seeing all variants helps you pick the best fit fast.

Removing diacritics and normalizing characters

Accents like é, ñ, and ç are common in titles and names. Some systems handle them well, others don’t. Removing diacritics maps “Crème brûlée” to “Creme brulee”. This makes links more consistent and easier to type. The tool also cleans special marks (such as smart quotes) and converts symbols like “&” to “and” so your slug reads naturally.

Should you always remove accents? If your site supports them and you value the exact spelling, you may keep them. If you want the safest string across systems, remove them. The checkbox lets you choose.

Percent-encoding, decoding, and safe links

URL encoding replaces unsafe characters with percent codes so a browser can read the address correctly. For instance, a space becomes %20, and non-ASCII characters use UTF-8 bytes with percent signs. Use encoding when you place user input into query strings or paths that must be URL-safe. For the technical details, see MDN on encodeURIComponent and related URL APIs (search for “MDN on encodeURIComponent”). For formal syntax, refer to the W3C URI syntax.

Decoding reverses this step. If you receive a link with percent codes, decoding shows the human-readable text. Not sure whether to encode or slugify first? Ask yourself: is this meant to be a clean path segment that humans read, or raw text going into a URL parameter? Paths often use slugs. Parameters often use percent-encoding.

Delimiters and readability

Hyphens are common in slugs because they read like spaces. Many style guides prefer hyphens for human-friendly URLs. Underscores are also supported and may be part of your existing pattern. The Delimiter setting lets you match your house style. For long titles, avoid stuffing every word. Drop stop words like “the” or “a” if the meaning stays clear.

Base URLs and safe joining

Building a full path by hand can create double slashes or missing separators. The Base URL field joins your base path and the new slug safely. For example, base “https://example.com/blog” and slug “summer-recipes” becomes “https://example.com/blog/summer-recipes”. This small helper prevents common errors, especially during migrations or bulk imports.

A quick example

Say you paste “Caffè Crème & Croissants: 10 Tips” and choose:

Click Generate. You’ll get:

  • Preferred slug: caffe-creme-and-croissants-10-tips
  • Slug variants: kebab-case and snake_case match the same tokens
  • URL encoded: Caff%C3%A8%20Cr%C3%A8me%20%26%20Croissants%3A%2010%20Tips
  • URL decoded: restores the original phrase
  • Joined URL: https://site.com/articles/caffe-creme-and-croissants-10-tips

Need a different style for a code identifier? Copy camelCase or PascalCase from the results.

Simple process, fewer errors

This workflow reduces copy-paste mistakes: pick your rules, generate once, copy the exact string you need, and save everything to CSV if you’re batching work. Working on content at scale? Use Copy all to keep a single note with every value for review.

Pro-Tips for Getting the Most Out of Slug and URL Work

  • Keep slugs short and focused - drop filler words and keep only the terms that add meaning.
  • Use hyphens for readability unless your system requires underscores - be consistent across your site.
  • Encode user input going into query strings - generate slugs for path segments you expect people to read.
What does this tool generate?
It creates a preferred slug using your settings, plus kebab-case, snake_case, camelCase, and PascalCase. It also shows URL encoded and URL decoded values. If you enter a base URL, it builds a joined full URL.
How does “Remove diacritics” change the result?
It strips accents from letters, turning “é” into “e” and “ñ” into “n”. This improves compatibility across systems and makes slugs easier to type. If you want exact spelling with accents, you can leave this off.
What’s the difference between kebab-case, snake_case, camelCase, and PascalCase?
kebab-case uses hyphens between words. snake_case uses underscores. camelCase starts with a lowercase word and capitalizes each next word. PascalCase capitalizes every word. Pick the style your project expects.
When do I use URL encoding vs a slug?
Use a slug for human-friendly path segments like /blog/best-coffee-beans. Use URL encoding for raw text going into a URL, such as query parameters or dynamic values with spaces or symbols. Encoding turns unsafe characters into percent codes.
Can I copy and export results?
Yes. Click Copy next to any output, or Copy all to grab everything with labels. Download CSV exports labels and values so you can keep records or share them in a spreadsheet.
