Frequently asked questions

Is it safe to use the Text Cleaner online?
Yes — and ours is safer than most. Many free online tools quietly upload your files to their servers to do the work. We don't. Everything happens inside your browser on your own device, so your files never reach the internet. There's no upload step, no server copy, and no way for us (or anyone else) to see what you're working on.
Are my files uploaded to a server?
No. There's no server-side processing here. The whole tool is a tiny app that runs in your browser — we don't even have a server that could receive your files. You can confirm this by opening your browser's network tab while you use the tool: nothing leaves your device.
Do I need to sign up or pay?
No. There's no account, no email collection, no credit card. The tool is free to use as much as you want, on as many files as you want. We're supported by a few unobtrusive ads on the page — not by your data.
Are filters case-sensitive?
Duplicate detection is case-sensitive. "Apple" and "apple" are kept separately. Use Case Converter first if you want case-insensitive dedupe.
Will it preserve internal HTML in <pre> blocks?
No — Strip HTML removes all tags indiscriminately. For more nuanced HTML processing, use a real HTML parser.
