Convert case online

Convert text to UPPER CASE, lower case, Sentence case, Title Case and three other cases instantly, as you type.

Paste any text and every letter turns into a capital as you type: "pay by Friday" becomes "PAY BY FRIDAY". Digits, punctuation and emoji stay as they are.

Paste text written in capitals and every letter becomes lowercase as you type: "PLEASE READ THE NDA" becomes "please read the nda". Numbers, punctuation and emoji are left alone.

Sentence case means only the first letter of each sentence is a capital, as in ordinary prose: "THE REPORT IS READY." becomes "The report is ready." Paste text and it is converted as you type.

Title case capitalizes the important words of a headline and keeps articles, short conjunctions and short prepositions lowercase: "how to train your dragon" becomes "How to Train Your Dragon". The first and last word always get a capital.

Alternating case switches between lowercase and capital letter by letter, "tHiS iS fInE", the style of the mocking SpongeBob meme. Type your text and copy the result into any chat or post.

Paste text with hard line breaks, for example from a PDF, and every line is joined into flowing text: "the lazy⏎dog" becomes "the lazy dog". Choose whether lines are joined with a space or with nothing, and whether paragraphs stay apart.

Paste text and every run of two or more spaces becomes a single space, tabs become spaces, and spaces at the start and end of each line are trimmed. Line breaks are kept, so lists and paragraphs keep their shape.

Paste a list and every repeated line is deleted, keeping the first occurrence of each and the original order. The tool shows how many duplicates it removed, and you can choose whether "Apple" and "apple" count as the same line.

Paste text and every blank line is deleted, including lines that look empty but contain spaces or tabs. All other lines stay exactly as they were, and the tool tells you how many lines it removed.

Type what to find and what to replace it with, and every match in your text is replaced as you type. Use plain text for simple swaps, or regex mode for patterns such as dates, emails and repeated spaces; the tool shows how many matches it replaced.

Paste a list with one item per line and it is sorted alphabetically as you type. Switch to Z → A, natural order (item 2 before item 10), length, reverse or shuffle with one click; accents and capitals sort where a reader expects them.

Paste or type your text to see the word count instantly, along with characters (with and without spaces), sentences, paragraphs, reading time, speaking time and your ten most frequent words. Everything updates as you write.

Type your text and get a bold version you can paste anywhere, even where there is no bold button: "Hello World 2026" becomes "𝐇𝐞𝐥𝐥𝐨 𝐖𝐨𝐫𝐥𝐝 𝟐𝟎𝟐𝟔". Choose serif bold or sans-serif bold, which looks closer to the fonts apps use.

Type your text and copy an italic version that keeps its slant in any app: "help is on the way" becomes "ℎ𝑒𝑙𝑝 𝑖𝑠 𝑜𝑛 𝑡ℎ𝑒 𝑤𝑎𝑦". Choose plain italic or bold italic.

Type a name or a phrase and get flowing cursive letters to paste anywhere: "Bella Rose" becomes "ℬℯ𝓁𝓁𝒶 ℛℴ𝓈ℯ". Choose the light Script style or the heavier Bold script, which stays readable at small sizes.

Type your text and get it in small capital letters, capitals the height of lowercase letters: "Hello World" becomes "ʜᴇʟʟᴏ ᴡᴏʀʟᴅ". Copy it into a bio, a caption, a game name or a chat.

Type your text and get it crossed out with a line you can paste into any app: "sold out" becomes "s̶o̶l̶d̶ ̶o̶u̶t̶". The line is part of the text itself, so it stays when you copy it between apps.

Type your text and get an underlined version that keeps its line in any app: "Read this" becomes "R̲e̲a̲d̲ ̲t̲h̲i̲s̲". Copy it into a caption, a bio, a comment or a message.

Type your text and it is turned upside down and reversed, so it reads correctly when you rotate the screen: "Hello world!" becomes "¡plɹoʍ ollǝH". Copy it into any message, post or comment.

Paste text to write it backwards: "Hello world" becomes "dlrow olleH". You can also reverse only the order of the words, or reverse the letters inside each word while the words stay in place. Emoji, flags and accented letters are kept whole.

Type your text once and see it in 16 fancy styles at the same time: bold, italic, cursive, gothic, double-struck, monospace, small caps, circled, squared, wide, strikethrough, underline and upside down. Each style has its own Copy button.

Type your text once and get it in 14 font styles that work on Instagram: bold, cursive, italic, small caps, gothic and more, ready to paste into your bio, captions and comments. The styles are ordered by how often people use them on Instagram.

Paste JSON to format it with 2 spaces, 4 spaces or tabs, or minify it to one line. The formatter validates as you type and points to the exact line and column of any error, such as a trailing comma or single quotes.

Paste a variable name, a phrase or a list of names and convert it to camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, dot.case or Title Case. Any style goes in: "max_retry_count" becomes "maxRetryCount", and acronyms are split correctly.

Paste a title to turn it into a URL slug: "10 Tips & Tricks for SEO!" becomes "10-tips-tricks-for-seo". Letters are lowercased, accents removed, Cyrillic transliterated, and everything else becomes a hyphen or an underscore. Paste a list to get one slug per line.

Paste Base64 to decode it to readable text, or paste text to encode it. Accents, Cyrillic and emoji work in both directions, and the URL-safe variant used in JWTs and URLs is one switch away: "SGVsbG8sIHdvcmxkIQ==" decodes to "Hello, world!".

Paste a percent-encoded link to decode it into readable text, or paste text to encode it for a URL: "caf%C3%A9%20au%20lait" decodes to "café au lait". Encode a single query value, or a full URL with its structure intact.

Type text to translate it into Morse code, or paste dots and dashes to decode them: "SOS" is "... --- ...". Letters are separated by a space and words by a slash. The translator covers the international alphabet, digits, punctuation, Russian Cyrillic and Spanish Ñ.

Get a new random UUID the moment the page opens, or generate up to 1,000 at once. Choose version 4 (fully random) or version 7 (time-ordered, ideal for database keys), uppercase or lowercase, with or without hyphens.

A strong random password is ready the moment the page opens: 16 characters from letters, digits and symbols, about 103 bits of entropy. Change the length and character sets and a new password is generated instantly, with a meter that shows its strength.

Pick a random whole number between a minimum and a maximum, both included: 1 to 100 by default. Ask for several numbers at once and turn on No repeats to draw like a raffle, where each number can come up only once.

Generate Lorem ipsum dummy text for designs, mockups and templates: choose paragraphs, sentences or words and how many you need. The text starts with the classic "Lorem ipsum dolor sit amet, consectetur adipiscing elit." and continues with fresh random sentences each time.
