About the Remove Invisible Characters

Text copied from the web, PDFs and chat apps often carries hidden characters like zero-width spaces and non-breaking spaces that break search, code and formatting.

This tool strips those invisible characters, converts non-breaking spaces to normal spaces and removes control characters, leaving clean, predictable text.

You can also collapse extra spaces and trim each line for a full cleanup, and it reports how many characters were removed.

Frequently asked questions

What is a zero-width space?
It is an invisible character with no width that can hide inside text, breaking searches, links and code without being visible.
Why convert non-breaking spaces?
Non-breaking spaces look like normal spaces but behave differently, which can cause layout and matching problems. Converting them normalises your text.
Is my text uploaded anywhere?
No. Cleaning happens entirely in your browser, so your text never leaves your device.
