Online Text Lab
A fast, privacy-first collection of text, number, and format tools for writers, developers, analysts, and students. Everything runs in your browser—no sign-ups and no data uploads.
Work faster with trusted online text tools
Welcome to Online Text Lab — a clean, no‑nonsense toolbox for everyday writing and formatting tasks. If you’ve ever bounced between five different sites just to check a word count, convert a headline to Title Case, validate a JSON snippet, or figure out a quick percentage, this site is for you. Everything is designed to be obvious, fast, and private. You paste or type; the page responds instantly. No accounts to create, no email gates, no uploading your drafts to a server you don’t control.
What you can do here in seconds
- Count words and characters in real time, including sentences, paragraphs, reading time, and speaking time.
- Fix capitalization with one click — lower, UPPER, Sentence, Title Case (with APA/Chicago options).
- Handle quick math like percent change, discounts, tips & split, or “percent of percent.”
- Create QR codes for URLs, Wi‑Fi, and text and download them to share or print.
- Unscramble letters for crosswords and word games with a flexible anagram solver.
Why people keep us open in a pinned tab
- Privacy by default: your text is processed locally in the browser. We don’t upload it.
- Instant feedback: results update as you type — no “calculate” button to press.
- Plain‑English accuracy: sensible rounding and readable precision without noisy trailing zeros.
- Lightweight UI: keyboard‑friendly controls, dark mode, and smooth performance even on modest laptops.
Real situations where these tools help
You’re polishing an application essay and need to stay under a hard character limit. You’re scheduling a post and want the headline properly capitalized for your style guide. You’re sanity‑checking a JSON payload before sending it to an API. You’re splitting a bill, factoring in a tip, and wondering how much each person owes. Or you just want an easy QR code for your guest Wi‑Fi. These are tiny tasks, but they can interrupt your flow. Our tools remove that friction so you can get back to the real work.

What we stand for
We care about speed, clarity, and trust. Pages should load fast, controls should be obvious, and explanations should be short and useful. We don’t track your text, and we don’t pretend a simple task needs a complicated workflow. As we add new tools, we prioritize real use cases from writers, students, editors, marketers, product teams, and developers who use these pages every day.
