Developer & Utility Tools

Generate strong, random passwords and passphrases in your browser — nothing is ever sent to a server.

Turn any headline into a clean, SEO-friendly URL slug — kebab, snake, camel, or dot case, in bulk if you need it.

Paste raw HTML and get valid, formatted JSX — with class → className, htmlFor, camelCase attributes, converted inline styles, and self-closed void tags.

Encode text or files to Base64 and decode back — with URL-safe variant, MIME line wrap, padding toggle, and full UTF-8 support. 100% client-side.

Live word, character, sentence, paragraph, reading-time, and keyword-density counts — as you type, entirely in your browser.

Live character, word, byte, and grapheme counts with real platform limits — SEO title tags, tweets, SMS segments, and Google Ads copy — all in one place.

Live reading, listening, speaking, and skim times — with language and content-type presets grounded in peer-reviewed data.

Percent-encode text for URLs and decode encoded strings back — supports encodeURIComponent, encodeURI, form-encoding (space as +), and per-line batch mode. 100% client-side.

Resize any image or video while keeping the ratio perfect — with common video, print, and social presets built in.

Convert text between 15 cases — Sentence, Title (AP), UPPER, lower, camelCase, PascalCase, snake_case, CONSTANT, kebab-case, Train-Case, dot.case, path/case, aLtErNaTiNg, iNVERSE, and reversed. 100% client-side.

Generate v4, v7, v1, v5, NIL, and MAX UUIDs in bulk — canonical, hex, uppercase, braces, and URN formats. Cryptographically secure and 100% client-side.

Generate placeholder text — paragraphs, sentences, words, lists, or exact byte counts. Four flavors (Lorem, Hipster, Corporate, Bacon) and four formats (plain, HTML, Markdown, JSON). 100% client-side.
