Slug Generator

How Do You Turn a Title into a URL Slug?

Enter Äpfel & Öl: für alle! in Text input. With the defaults, the result is apfel-and-ol-fur-alle. Open Slug options and choose German to ASCII (ü → ue) to get aepfel-and-oel-fuer-alle. Results update immediately; use Copy slug when the preview matches your intended path.

A slug is the readable part of a URL that identifies a page. For example, in https://example.com/articles/writing-better-titles, the final segment is writing-better-titles. Paste your heading into the input to see its slug immediately. The default settings lowercase the text, convert common Latin accents to ASCII, and replace punctuation or whitespace with hyphens. You can preserve case or use underscores when your application's naming rules call for them. Review a generated slug before publishing it. A useful path describes the page without relying on an internal number or a temporary draft title. This tool performs character conversion; it does not summarize text, translate titles, remove stop words, or decide which words matter most. Edit the source title if you want a shorter or more descriptive result. Use the word counter to inspect a longer title or draft.

How Can You Generate Slugs for Multiple Titles?

Enable batch mode and paste one title per line. Each nonblank line becomes one result, so a list of article headings or product names can be prepared together. Blank lines are ignored. Results retain the order of the remaining titles, which makes the TXT output suitable for pasting alongside an existing ordered list. With batch mode off, line breaks are treated as separators inside a single title instead. Enable unique slugs when several titles could produce the same path. For example, Hello! and Hello? both normally become hello. With uniqueness enabled, the second result becomes hello-2. The generator also checks collisions introduced by the length limit. This check covers only the current batch: it cannot tell whether a path is already in use on your site. Compare exported results with your existing routes before importing them.

Which Character Mode Should You Choose?

Latin to ASCII handles accented Latin letters and common exceptions such as æ → ae, ø → o, and ł → l. It normalizes composed and decomposed accents so equivalent Latin text produces the same result. In this mode, symbols are expanded as separate words: AT&T becomes at-and-t, and €5 becomes euro-5. Preserve Unicode retains letters, numbers, and combining marks from international scripts. A title such as 你好 世界 becomes 你好-世界 rather than an empty result. This mode does not translate or romanize the title. ASCII only keeps ASCII letters and digits without converting accented letters: café becomes caf. Choose the mode that matches the receiving system's rules, and inspect the preview when changing modes.

Character modes with Lowercase enabled, hyphens, and no length limit

Characters option	Input	Generated slug
Latin to ASCII (ü → u)	Crème Straße	creme-strasse
German to ASCII (ü → ue)	für alle	fuer-alle
Preserve Unicode	你好 世界	你好-世界
ASCII only (remove accents)	café noir	caf-noir

When Should You Use German Transliteration?

Choose German to ASCII when umlauts should become letter pairs: ä → ae, ö → oe, and ü → ue. Both transliteration modes convert ß → ss; the difference is how they handle umlauts. This is a spelling conversion, not language detection or translation. The setting applies to every title in the batch, so separate lists if they need different rules.

Spelling conversions can introduce collisions. In German mode, für and fuer both produce fuer. With Make slugs unique within this batch checked, that ordered pair becomes fuer and fuer-2. Reordering the titles can change which one receives the unsuffixed path. Keep a title-to-slug mapping when assigning permanent routes.

How Are Length Limits and Invalid Titles Handled?

The maximum character setting uses Unicode code points rather than UTF-8 byte length or the length of a percent-encoded URL. A value of zero leaves the length uncapped. A positive value truncates the generated slug and removes any trailing separator. This can split a word and does not guarantee a complete visual grapheme when a script uses combining marks. A destination with a byte-based limit needs a separate check. For Hello world, a limit of six produces hello because the trailing hyphen is removed; a limit of three produces hel. Numeric uniqueness suffixes count toward the same maximum. If there is insufficient room for a base and its suffix, the affected line receives a warning. Titles that contain only unsupported characters receive warnings too. Export remains disabled until every nonblank title has a valid result. This keeps the exported list aligned with the input instead of silently dropping unsuccessful conversions.

Why Are Character and Percent-Encoded Lengths Different?

In single-title mode, the status line shows characters and bytes when percent-encoded. It calculates the first with Unicode code points and the second with the length of encodeURIComponent(slug). For café in Preserve Unicode mode, that is four characters and nine when percent-encoded: caf%C3%A9. The encoded representation has nine ASCII characters; the unescaped text itself occupies five UTF-8 bytes. These are different measurements.

The character limit does not cap that encoded measurement. Batch mode shows the title count and how many need attention instead of individual length totals. If your receiving system limits encoded path length, inspect a title in single mode and confirm what the system actually counts. Use the character counter for separate text inspection.

How Do You Copy or Download the Results?

Copy slug or Copy all places the output on the clipboard. If browser clipboard access fails, an explanatory message tells you to select and copy the output manually. Download TXT saves the same results as slugs.txt, with one slug per line in batch mode and no extra column labels. The output field remains selectable, and Clear input removes the current titles without resetting your chosen options. All conversion runs locally in your browser. The tool sets no fixed batch-size cap, but very large lists can take longer or use more memory on a phone. For URL escaping rather than title conversion, use URL encode/decode. Keep the distinction in mind: this generator creates path names; it does not encode an entire URL or validate the availability of a published address.
