Deslugify Tool

How to use

1. 1Choose Single slug to convert one value, or Bulk to convert one slug per line. Click Load sample to see realistic input.
2. 2Paste a slug, identifier, or URL. The tool detects kebab-case, snake_case, camelCase, PascalCase, dot.case, and full URLs automatically.
3. 3Pick an output case: Title Case, Sentence case, Start Case, lower case, or UPPER CASE.
4. 4Adjust the options if needed: split camelCase, split letter and number boundaries, strip URL parts, keep acronyms upper case, and lower case small words in Title Case.
5. 5Read the result, check the detected words, and use Copy (or Copy all in bulk mode) to grab the readable text. Everything runs in your browser.

About this tool

Deslugify Tool is the inverse of a slug generator: it takes a slug, a code identifier, or a URL and turns it back into readable text. A slug like my-first-blog-post, a database column like user_first_name, a function name like getUserProfile, or a path like /blog/web-development/css-grid-explained all encode real words behind separators and casing rules, and this tool reconstructs those words and renders them in the case you choose. It recognizes every common format in one pass. Hyphens, underscores, dots, slashes, plus signs, and colons are all treated as word separators, so kebab-case, snake_case, dot.case, and URL paths split the same way. camelCase and PascalCase are split on the lower-to-upper boundary, and a run of capitals is kept with its acronym, so HTMLParser becomes HTML Parser rather than H T M L Parser. camelCase splitting handles mp3File as mp3 File, and a number followed by a letter is split too, while a letter followed by a digit is kept joined so codec and encoding tokens like mp3, h264, and base64 stay whole. With URL cleanup enabled, a full link pasted from the address bar is reduced to its readable path: the scheme, host, query string, fragment, and a known file extension such as .html or .php are stripped before the words are split, so you get a clean heading instead of the whole address. Output casing covers what people actually need: Title Case, which keeps a curated set of acronyms (API, CSS, HTML, SEO, JSON, and more) upper case and keeps short connector words like of, the, and, and to lower case in the middle while always capitalizing the first and last word; Sentence case; Start Case, where every word is capitalized with no small-word exceptions; lower case; and UPPER CASE. A single-slug mode shows the detected words and every output case side by side so you can copy whichever fits, and a bulk mode converts one slug per line so a whole column of URL slugs becomes a column of clean titles for a sitemap audit, a content inventory, a CMS import, or a set of page headings. Common uses include turning URL slugs into article titles, generating human labels from enum values or database fields, building breadcrumb and navigation text from paths, and cleaning up exported filenames. Everything runs locally in your browser, so the slugs, identifiers, and URLs you paste are never uploaded.
