Case Converters
Sentence Case Converter
Paste in text typed with the caps lock on, dumped from an all-caps PDF, or just formatted inconsistently, and this tool rebuilds it into proper sentence case: the first letter of every sentence capitalized, everything else lowercase, and every lone ‘i’ turned into ‘I’.
Lower Case Converter
Drop in any text and get it back with every single letter lowercased — useful for cleaning up shouty ALL CAPS text, normalizing data before comparison, or just matching a lowercase style guide.
Uppercase Converter
This uppercase converter takes any text and capitalizes every letter, turning lowercase and mixed-case writing into ALL CAPS — handy for headings, legal disclaimers, license plates, or just adding emphasis.
Capitalized Case Converter
Capitalized Case — sometimes called Start Case — uppercases the first letter of every single word and lowercases the rest, no exceptions for short connector words. It's the format you want for names, headings, and menu items.
Alternating Case Converter
Turn plain text into aLtErNaTiNg cAsE — the mocking ‘SpongeBob meme text’ format that flips between lowercase and uppercase on every letter. Great for sarcastic captions, memes, and comments.
Title Case Converter
Not sure how to title an essay, headline, or blog post? This title case converter capitalizes the important words and keeps short connecting words like ‘a’, ‘the’, and ‘of’ in lowercase — unless they're the first or last word of the title.
Inverse Case Converter
InVeRsE CaSe (also called swap case or toggle case) flips every letter's case: uppercase becomes lowercase and lowercase becomes uppercase, letter by letter, leaving everything else untouched.
Text Style Generators
Bold Text Generator
This generator doesn't apply CSS bold — it swaps each letter for its Mathematical Bold Unicode look-alike, so the bold styling travels with the text itself and works in places that don't support rich text, like Instagram bios, tweets, and Discord messages.
Italic Text Generator
Type your text and get it back slanted into italics using Unicode's Mathematical Italic letters — copy and paste it anywhere plain text is accepted, no formatting toolbar required.
Underline Text Generator
Underline any text without needing a rich-text editor. This tool inserts a combining underline mark after every character, so the underline is baked into the text and pastes correctly into plain-text fields.
Strikethrough Text Generator
A quick way to cross out text: type it normally and watch it get a line struck through every character, ready to copy and paste into a chat, bio, or document — no special formatting needed on the other end.
Fancy Text Generator
One box, a dozen fonts. Type your text once and get it back in bold, italic, bold italic, script, Gothic/Fraktur, double-struck, monospace, circled, squared, and small caps — all real Unicode characters you can paste straight into social bios.
Wide Text Generator
Also known as the aesthetic font generator, this widens every character using Unicode's fullwidth forms — the same visual style commonly seen in aesthetic social media captions.
Mirror Text Generator
Mirror text is the same text you'd see reflected in a mirror — each letter is horizontally flipped and the whole string is reversed. Print it out and hold it up to a mirror to read it normally.
Upside Down Text Generator
Flip your text a full 180 degrees using rotated Unicode look-alike letters, reversed end to end — the classic ‘ˉʇxǝʇ uʍop-ǝpɪsdʇ’ effect for jokes, bios, and pranking your friends' group chat.
Reverse Text Generator
A fast way to flip text back to front: type it normally and get the character order fully reversed, letter by letter — handy for backwards messages, puzzles, and palindromes.
Small Text Generator
Takes regular-sized text and shrinks it into two popular tiny-text styles: small caps (ᴀᴀ-style capitals) and superscript (ʰᵉʳᵉ-style raised letters) — both are real Unicode characters, not an image or font swap.
Zalgo Glitch Text Generator
Stack random combining diacritical marks above, below, and through your text to produce the classic glitchy, ‘corrupted’ Zalgo effect — popular for creepypasta, spooky posts, and internet chaos.
Invisible Text Generator
Generates truly invisible Unicode characters you can copy and paste anywhere an app refuses to accept a blank message — empty-looking WhatsApp texts, blank Discord messages, invisible Instagram usernames, and more.
Encoders & Translators
Morse Code Translator
Translate plain English into Morse code, or paste in dots and dashes to decode them back to text — with a built-in audio player so you can hear your message beeped out loud.
Binary Code Translator
Convert plain text into binary (each character as an 8-bit sequence of 0s and 1s), or paste in space-separated binary bytes to decode them straight back to readable text.
Base64 Encoder / Decoder
Encode any text into Base64, or paste in a Base64 string to decode it back to readable text — all processed locally in your browser, nothing is sent to a server.
Wingdings Translator
A playful symbol cipher inspired by the classic Wingdings font: each letter maps to a common Unicode dingbat symbol, and the translator works in both directions. Note this uses standard Unicode symbols rather than the proprietary Wingdings font itself, so it displays consistently everywhere, including outside Windows.
NATO Phonetic Alphabet Translator
Spells out your text using the NATO phonetic alphabet (Alpha, Bravo, Charlie...) — the same system pilots, the military, and call centers use to communicate letters clearly over radio or phone.
Leetspeak Translator
Turns normal text into 1337sp34k by swapping common letters for lookalike numbers (a→4, e→3, i→1, o→0, s→5, t→7...) — the classic internet-forum and gamer-tag style.
Generators
Slug Generator
Turns any title or sentence into a clean, URL-safe slug: lowercased, stripped of accents and punctuation, and joined with hyphens (or underscores) — ready to drop straight into a blog post or product URL.
Lorem Ipsum Generator
Generate classic Lorem Ipsum placeholder text by the word, sentence, or paragraph — useful for filling out mockups, wireframes, and templates before real copy is ready.
Password Generator
Generates a strong random password of whatever length and character mix you choose, using your browser's cryptographically secure random number generator. Nothing is sent to a server — the password never leaves your device.
Text Analysis
Word Counter & Text Analyzer
Paste in any text to instantly see its character count, word count, sentence count, paragraph count, and estimated reading and speaking time — useful for essays, social posts with character limits, and scripts.
Word Frequency Counter
Analyzes any block of text and shows exactly how often each word appears, ranked from most to least frequent, with an optional filter for common stop words and a simple visual word cloud.
Reading Time Calculator
Paste in an article, blog post, or script to get an estimated reading time and speaking time, alongside a full word and character breakdown — handy for writers who want to show a ‘5 min read’ estimate.
Date & Number Tools
Roman Numeral Date Converter
Pick a date and get it converted into Roman numerals in your choice of format — a popular way to render a wedding date, birthday, or anniversary for a tattoo, ring engraving, or keepsake.
Number to Words Converter
Type in any number and get it spelled out in plain English words — useful for writing cheques, legal documents, or just double-checking how a large number is actually said out loud.
