About InputTesting

What Is InputTesting?

InputTesting.com is a collection of 37 free, browser-based text processing tools. Whether you need to clean up messy spacing, convert case, generate invisible characters, or validate JSON and HTML — we have a tool for it. No account. No file uploads. No data sent to any server. Everything runs directly in your browser.

Why We Built This

Most online text tools are either paywalled, ad-heavy, or require you to sign up just to paste some text. We wanted something different — fast, clean, and completely free. InputTesting exists to save developers, writers, marketers, and everyday users the frustration of hunting for a reliable tool.

• No accounts: Use any tool instantly without signing up
• No limits: Process as much text as you need
• Private by default: Your text never leaves your browser
• Works everywhere: Desktop, tablet, and mobile — fully responsive
• Always free: Every tool on the site is 100% free to use

Our Tools

We currently offer tools across 5 categories:

• Text Cleaning — Remove spaces, blank lines, duplicates, HTML tags, and more
• Text Formatter — Format paragraphs, sort lines, join text, beautify content
• Case Converter — Uppercase, lowercase, title case, sentence case, and more
• Invisible Character — Generate zero-width spaces, blank characters, and invisible text
• Validators — Validate JSON, HTML, XML, CSS, URLs, and email addresses

Privacy Policy

Your text stays on your device. We do not transmit, store, or log any text you enter into our tools. All processing happens client-side in your browser using JavaScript. We may use basic analytics to understand traffic (page views, not content), but your actual input data is never collected.
