Available Text Tools
Case Converter
Transform text between every common letter-case style instantly. Perfect for developers renaming variables, content creators generating URL slugs, editors fixing all-caps emails, or anyone needing consistent text formatting. Ten different case styles handle any conversion need.
Regex Tester
Develop and debug regular expressions with live testing against your sample text. Visual match highlighting shows exactly what matches. Inspect capture groups, test replacement strings, and toggle all JavaScript regex flags. A 200ms execution timeout prevents runaway patterns from freezing your browser.
Text Cleaner
Transform messy, disorganized text into clean, structured content. Remove duplicate lines, strip empty lines, eliminate HTML tags, normalize whitespace, and sort alphabetically. The composable cleaning pipeline lets you apply any combination of operations in a single pass. Essential for data cleaning, log analysis, list deduplication, and content preparation.
Diff Checker
Identify differences between two versions of text with visual line-by-line comparison. Added lines highlighted in green, removed lines in red, and changed sections clearly marked. Useful for code reviews, legal document comparison, editing feedback, and version control visualization.
Word Counter
Comprehensive text analysis with live statistics as you type. Count words, characters (with and without spaces), sentences, paragraphs, and lines. Get automatic estimates for reading time and speaking time, plus identification of your most frequently-used words. Essential for writers, students, editors, and content creators.
About Text Tools
Our text tools are designed to handle your files with complete privacy. Unlike online services that upload your documents to remote servers for processing, all our tools run entirely within your browser using WebAssembly technology. This means your sensitive files — whether they're financial documents, personal records, or confidential business materials — never leave your device.
Each tool is optimized for speed and reliability. We use industry-standard libraries like MuPDF for PDF operations, compiled to run at native speeds in your browser. There's no queue, no waiting, and no limits on file size beyond what your device can handle.
