About CleanText.online
Privacy-first text tools that respect your data — everything runs locally in your browser.
CleanText.online is a collection of free, privacy-first online tools for text cleaning, data masking, format conversion, and developer utilities. Founded with the belief that your data should never leave your device, all tools are built to process information entirely in your browser — no uploads, no servers, no tracking.
1 Our Mission
To provide high-quality, reliable text processing tools that respect user privacy. We believe that using an online tool should not require you to trust a server with your sensitive data. Every tool on this site is designed from the ground up to work without any server-side processing.
2 How It Works
When you use a tool on CleanText.online, the processing code is downloaded to your browser when the page loads. All subsequent operations happen in your browser's memory using JavaScript. Nothing you type, paste, or upload is ever transmitted to any server.
You can verify this yourself: load any tool page, disconnect from the internet, and the tool continues to work perfectly. Open your browser's Developer Tools (F12) and check the Network tab — zero data transmission occurs when you use the tools.
3 What Makes Us Different
Unlike most free online tools that send your data to remote servers for processing, CleanText.online processes everything locally. This means:
- No data uploads — your data never leaves your device
- No server logs — there's nothing to log
- No data retention — close the tab and it's gone
- No third-party access — your data is yours alone
