Free Online Text Tools & Utilities

Online text tools, converters & calculators in one tab

Text Tool Suite is a focused set of tools you reach for every day: a word counter & character counter for essays and articles, a case converter for titles and UI strings, a JSON formatter for payloads, a percentage calculator for discounts and percent change, and a QR code generator for links and Wi-Fi. Everything runs in your browser so you get instant results without installing anything.

Writing tools

• Track length with the online word counter – live word count, character count (with and without spaces), reading time, speaking time, and keyword density.
• Fix capitalization with the online case converter – switch between lowercase, UPPERCASE, Sentence case, Title Case, camelCase, snake_case, kebab-case, and more.
• Clean messy copy with Advanced Text Cleaner – strip extra spaces, hidden characters, HTML tags, and odd punctuation before pasting into a CMS.
• Generate placeholder copy with the lorem ipsum generator – words, sentences, or paragraphs as plain text or HTML.
• Draft and preview with the Markdown editor – GitHub Flavored Markdown with live preview, great for README files and docs.
• Check clarity with the readability test tool – Flesch, Flesch-Kincaid, Gunning Fog, and more scoring algorithms with live results.

Developer & data tools

Sanity-check a payload, run a one-off conversion, or debug a regex without opening a full IDE.

• Format and validate with the JSON formatter & validator – pretty-print, sort keys, and check against a JSON Schema.
• Convert data with CSV to JSON and JSON to CSV for quick import and export transformations.
• Encode and decode with Base64 encoder / decoder and URL encoder / decoder for tokens, query strings, and redirects.
• Inspect any link with the URL parser – break a URL into protocol, host, path, query params, and hash in one view.
• Generate checksums with the hash generator – MD5, SHA-1, SHA-256, SHA-512 for text or uploaded files.
• Debug patterns with the regex tester – live match highlighting, replace preview, capture groups, and saved snippets.
• Compare documents with the difference checker – line, word, or character-level diffs side by side.
• Convert colors with the color converter – HEX, RGB, HSL, HSV, CMYK with WCAG contrast ratios and palette export.
• Translate number formats with the number base converter – binary, octal, decimal, hex, and ASCII.
• Protect snippets with secure text encryptor – browser-side AES-256-GCM encryption for notes, tokens, and small secrets.

Utilities & calculators

• Remove duplicates from lists of emails, tags, or IDs.
• Remove extra spaces and line breaks that sneak in from copy-paste.
• Reverse text, reverse words, or reverse lines for puzzles and data cleanup.
• Sort lines alphabetically when tidying a list or config file.
• Find & Replace multiple terms at once across a block of text.
• Create shareable QR codes for URLs, Wi-Fi credentials, and contact cards, with custom colors, logo overlay, and PNG/SVG export.
• Build secure credentials with the password generator or practice typing with the typing speed test.
• Pull contact addresses with Extract Emails – scan any block of text or uploaded file for email addresses, deduplicate, and export as TXT or CSV.
• Resize images in bulk with the bulk image resizer – convert to WebP, JPG, or PNG, add watermarks, and download as a ZIP.
• Do quick math with the percentage calculator, time duration calculator, and unit converter instead of opening a spreadsheet.
• For games and picks, use the random number generator or word unscrambler / anagram solver.

How to use Text Tool Suite

1. Open a tool from the grid or search for what you need: try “word counter”, “json formatter”, “percentage”, or “QR code”.
2. Paste or type your content. Most tools show live results as you edit and highlight the key stats you need.
3. Copy, download, or export the output. When you’re done, jump to a related tool to keep your workflow moving.

FAQ

Is everything really free?

Yes. All tools are free to use with no account, no trial, and no email wall. Open the site, pick a tool, and start working.

Do you store my text or files?

No. Tools run client-side, which means processing happens in your browser. Your text, numbers, and uploads stay on your device.

Does it work on phones and tablets?

Yes. Text Tool Suite is responsive and tested on current versions of Chrome, Safari, Firefox, and Edge on desktop and mobile.

What kinds of tools are included?

The suite covers five areas: Writing (word counter, readability test, markdown editor, lorem ipsum), Text Manipulation(case converter, text cleaner, find & replace, sort lines, remove duplicates, reverse text), Developer Tools (JSON formatter, Base64, URL encoder/parser, regex tester, hash generator, CSV to JSON converters, difference checker), Utilities (QR code generator, password generator, extract emails, bulk image resizer, word unscrambler, typing speed test), and Calculators (percentage, unit converter, random number, time duration, number base converter).

Can I use these tools without an internet connection?

Most tools work offline once the page has loaded because all processing runs client-side. Features that pull external data (such as the QR scanner) require an active connection.

What is the word counter useful for?

The online word counter tracks words, characters (with and without spaces), sentences, paragraphs, reading time, speaking time, and keyword density in real time. Writers use it for essays, blog posts, and SEO copy; students use it to hit word limits; and social media managers use it to stay within platform character limits.

If there’s a tiny utility you wish existed: a new converter, a formatter, or a text helper you keep rebuilding in spreadsheets, let me know. Text Tool Suite grows over time, but the goal stays the same: small, fast, and privacy-friendly tools that help you finish real work a little quicker.
