Text copied from certain applications, old file formats, or corrupted sources can carry invisible control characters — leftover formatting codes, null bytes, or other non-printable bytes — that don't display visibly but can break parsing in strict systems.
This tool scans your text and strips out control characters outside the standard printable range (excluding normal newlines and tabs, which remain intact), reporting how many were found and removed.
This is a useful debugging step when text behaves unexpectedly in a script or system that's stricter about character validity than a typical text editor, which often silently tolerates or hides these invisible characters.
Because everything runs locally in your browser, results appear instantly and nothing you type or upload is ever sent to a server.
Bookmark this page if you expect to use this tool regularly — it loads fast and behaves the same way every time, with no account needed.
This kind of task shows up constantly in everyday writing, coding, design, and admin work, which is exactly why a dedicated, focused tool saves so much back-and-forth.
A tool that does one job well, without a cluttered interface or unrelated features competing for attention, tends to be faster to use than a heavier all-in-one app.
If you find yourself needing this often, keeping this page open in a tab is usually faster than digging through a bigger software suite's menus.
Because there's no sign-up or installation step, you can jump straight from a search result to a working tool in a couple of seconds.
The interface is intentionally simple, so there's no learning curve — the input goes in, the result comes out, and that's the whole interaction.
Frequently asked questions
Does this remove tabs and newlines too?
No, standard newlines and tab characters are preserved since they're legitimate formatting characters — only genuinely non-printable control characters are stripped.
How would these invisible characters end up in my text in the first place?
They commonly come from copying content out of certain PDF readers, older document formats, or data exported from systems with encoding issues.
