TextKit: The Complete Guide to Browser-Local Text Tools

Word Counter /word-counter

The word counter gives you a live word count, character count, sentence count, paragraph count, and reading time as you type. It is the workhorse tool of the site, the one writers leave open in a tab while drafting blog posts, email replies, college essays, and product descriptions. The companion guide on blog post length covers the optimal word count by content type and the recent changes in how AI search engines treat length as a citation signal.

Character Counter, Twitter, SMS, Meta Description /character-counter

If you have searched count characters for twitter, count twitter characters, or character count for tweet, the TextKit character counter is the tool. Live limits for Twitter (280), Instagram captions, LinkedIn posts, SMS (160 GSM-7, 70 UCS-2), Facebook, TikTok, and a handful of meta-tag limits. Emoji are counted by their actual code-point weight, which matters more than most casual tools admit. The deeper background sits in the complete guide to character count, where character count actually matters, how the Twitter limit became 280, and the emoji and surrogate-pair gotchas.

Remove Extra Spaces /remove-spaces

The remove spaces tool collapses double spaces to single, strips leading and trailing whitespace, removes blank lines, and tidies the kind of irregular spacing that copy-paste introduces. The same page answers the related queries, remove spacing, remove blank spaces, how to remove double spaces, because the underlying operation is the same. Anyone who has pasted a paragraph from a PDF into a CMS knows why this exists.

Remove Duplicate Lines /remove-duplicates

If you have a list of email addresses, URLs, names, SKUs, or anything else that should be unique and is not, remove duplicate lines is the tool. Options to ignore case, ignore leading whitespace, sort alphabetically after dedup, or preserve original order. The same page handles the remove duplicate online search-intent that brings most users here. The how-to guide on removing duplicate lines covers the three edge cases that break most dedup workflows, case sensitivity, whitespace, order preservation, and the patterns that handle all three at once.

Find and Replace with Regex /find-replace

The find and replace tool does plain-text search-and-replace with case-insensitive and whole-word options, and full JavaScript-flavored regex for everything more complex. Useful for the search and replace in javascript and regex replace test queries that bring developers to the site, paste, write the pattern, see the result, copy it back. No script to write, no IDE to open.

Case Converter, UPPERCASE, lowercase, camelCase, snake_case, kebab-case /case-converter

The case converter handles ten transformations: UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, kebab-case, SCREAMING_SNAKE_CASE, and dot.case. Instant and Unicode-correct, the German ß, the Turkish dotless i, and the accented vowels of Spanish and Portuguese all behave the way the language specifies, not the way a naive uppercase function defaults. The complete guide to case conversion covers the AP, APA, and Chicago title-case rules and the Unicode gotchas that catch the casual implementations.

JSON Formatter, Validator, Minifier /json-formatter

The JSON formatter pretty-prints, validates, and minifies JSON. Paste raw JSON, get a formatted version with sortable keys, configurable indentation, and a clear error pointer when something is malformed. The companion guide, validating JSON in 2026: browser vs VS Code vs jq, is the field guide for which validator to use when. The browser tool wins for one-off pastes. jq wins for streaming. VS Code wins for schema-aware editing.

Text Diff, Compare Two Texts Side by Side /text-diff

The text diff tool compares two pieces of text and highlights every added, removed, and changed line. Useful for proofreading two drafts, comparing API responses, checking whether a translation matches the source, or auditing what an AI assistant changed when you asked it to "improve" a paragraph.

Hash Generator, MD5, SHA-1, SHA-256, SHA-512 /hash-generator

The hash generator computes MD5, SHA-1, SHA-256, and SHA-512 hashes of any string. Browser-local, which matters more here than anywhere else on the site, because hashing a password or an API key on a server-side tool would be a security violation. TextKit's runs in the browser. The input string never leaves the page.

Base64 Encoder and Decoder /base64

The Base64 tool encodes plain text to Base64 and decodes Base64 back to plain text, with full UTF-8 support so accented characters, CJK ideographs, and emoji round-trip correctly. The kind of tool you need three times a year and want to find in under five seconds.

Binary Code Translator /binary

The binary code translator converts text to binary and binary back to text. UTF-8 supported, multi-byte safe, emoji friendly. The accompanying complete guide to binary translation walks through how a translator for binary actually turns text into base-2 and back, the byte, the bit, UTF-8 versus ASCII, the surrogate-pair handling for non-BMP characters.

Sort Lines, Alphabetical, Numerical, by Length /sort-lines

The sort lines tool handles the queries readers actually type: sort lines alphabetically, sort lines by length, numerical sort for lists of numbers, and reverse sort. Case-insensitive and unique options are toggles, not separate tools. The guide on sorting lines covers the five sort orders and how to get each in the browser, in Excel, and in the command line.

Shuffle Lines, True Fisher-Yates /shuffle-lines

The shuffle lines tool randomizes the order of any list using a real Fisher-Yates shuffle. The accompanying article explains why the wrong shuffles to avoid, the naive sort-with-random-comparator that still ships in too many tutorials, produce biased orderings, and when a uniform random permutation actually matters.

Add Prefix and Suffix to Each Line /prefix-suffix

The prefix and suffix tool wraps every line in custom text, quotes, brackets, HTML tags, SQL values, JSON quotes, markdown bullets. The classic five patterns are covered in the how-to guide, alongside the cleanup step that prevents the trailing-comma error in SQL IN clauses.

Morse Code Translator /morse-code

The Morse code translator converts text to Morse and Morse back to text, with audio playback at the standard 20 WPM. ITU standard, browser-local, with the dits and dahs synthesized in the page. The complete guide to Morse code covers the 1844 origin, the difference between ITU and American Morse, the PARIS WPM standard, and the audio-synthesis logic the tool uses.

Pig Latin Translator /pig-latin

The Pig Latin translator encodes English to Pig Latin and decodes back. Classic schoolyard rules, words beginning with a consonant get the consonant moved to the end plus -ay; words beginning with a vowel get -way (or -yay, or -hay, depending on the variant). The complete guide covers the two rules, the regional variants, the consonant-cluster edge cases, and the schoolyard history.

Lorem Ipsum Generator /lorem-ipsum

The Lorem Ipsum generator produces placeholder text by paragraphs, sentences, or words. Classic Cicero-derived Lorem Ipsum, or random pseudo-Latin if you need filler that looks plausibly Latin without being the famous passage. The query latin for text brings a surprising number of designers and writers here. The complete guide to Lorem Ipsum covers where it actually comes from (a scrambled passage from Cicero's De finibus), why designers still use 500-year-old fake Latin, when it hurts the work, and the modern alternatives worth knowing about.

Random Word Generator /random-word

The random word generator produces English words on demand, filterable by part of speech, noun, adjective, verb, adverb. Click to copy. Useful for writing prompts, brainstorming sessions, vocabulary games, password seeds, and the seven other use cases covered in the complete guide.

Bold Text Generator, Unicode Fonts /bold-text

The bold text generator converts plain text into bold, italic, cursive, fraktur, monospace, or outlined Unicode characters you can paste anywhere, Instagram bios, LinkedIn headlines, Twitter posts, email subject lines, places that do not support real formatting. The accompanying guide explains how the Mathematical Alphanumeric Symbols block of Unicode makes this work and why some characters fall back to regular when they hit a platform that does not support the full range.

Invisible Text Generator /invisible-text

The invisible text generator outputs blank Unicode characters, useful for empty Instagram bios, WhatsApp message spacing, Discord username tricks, and the surprisingly common requirement of "submit this form even though the field cannot be empty." The complete guide documents which characters paste cleanly on which platforms and which ones get stripped by content filters.

Text Reverser, Text Repeater, Markdown Table Generator /text-reverser, /text-repeater, /markdown-table

The text reverser handles four reversal modes, characters, words, lines, and reverse-each-line. The text repeater repeats any text with configurable separators and counts. The markdown table generator builds GitHub-flavored markdown tables from scratch or from pasted Excel ranges, with live preview. The supporting essays, the complete guide to markdown tables, the syntax cheatsheet, the 60-second how-to, and the markdown vs HTML tables comparison, cover every edge case the table tool can produce.

Palindrome Checker /palindrome

The palindrome checker answers the question the queries check for palindromes, palindrome finder, and palindrome text ask: is this word, phrase, or sentence the same forward and backward? Ignores spaces, punctuation, and case, the way the classic palindrome convention requires.

URL Slug Generator /url-slug

The URL slug generator turns any title, a blog post, a product name, a heading, into a clean, SEO-friendly URL slug. Handles transliteration of accented characters and non-Latin scripts, stop-word removal, custom separators (hyphens, underscores, dots), and the length-trimming heuristics search engines actually reward.

This is the cluster TextKit has invested the most editorial effort in. Four long-form guides anchor the slug topic: how to create a URL slug in five seconds, the definitive 2026 guide to URL slug SEO, dash vs underscore in URLs and how Google reads each, and URL slugs in the age of AI search, because ChatGPT, Perplexity, and Gemini now cite URLs as sources, and slug clarity has begun to influence whether an AI engine picks one source over another.

Email Extractor /email-extractor

The email extractor pulls a clean, deduplicated list of every email address out of any block of text, resumes, scraped web pages, CSV dumps, conference programs, Slack exports. Because it is browser-local, none of those email addresses ever cross the network. The companion essays, the complete guide to email extraction, the email regex cheatsheet with worked examples, the free vs paid email extractor comparison, the Hunter.io versus free extractors review, and the how-to-extract-emails-from-text walkthrough, cover the regex patterns, the obfuscation handling, the deliverability verification step, and the legal limits.
