Invisible characters like zero-width spaces and byte-order marks are real characters that cost tokens and break search and diffs, even though you can't see them. Everything runs in your browser; nothing is uploaded.

Questions
- Is Clean Text free?
- Yes. Clean Text is completely free, with no account, no sign-up, and no usage limits. It runs entirely in your browser.
- Do my files get uploaded when I use Clean Text?
- No. Clean Text processes everything on your device, so your files and text never leave your browser. You can verify it yourself: open your browser's Network tab and you'll see no uploads.
- How do I use Clean Text?
- Open Clean Text in your browser, no install or sign-up needed, then paste, type, or drop in your input and the result appears instantly. Strip the invisible junk that copying from PDFs, Word and the web leaves behind: zero-width spaces, byte-order marks, control characters, non-breaking spaces, smart quotes and stray whitespace. These cost tokens and break search and diffs even though you can't see them. Browser-only, nothing uploaded.
- Is there a file size limit in Clean Text?
- There's no hard file or text size limit. Because Clean Text runs locally in your browser, the only ceiling is your device's available memory, and everyday files process instantly.
