The Tool for Removing Invisible & Non-Printable Characters from Text
Non-printable characters are invisible symbols embedded in text that can disrupt data processing, formatting, or display. Examples include ASCII control codes, zero-width spaces, and other invisible characters. They commonly appear when copying content from PDFs, emails, spreadsheets, or code files. Using this tool, you can easily remove all non-printable characters and optionally strip tabs or newlines to ensure your text is clean and standardized.
What Are Non-Printable Characters?
Non-printable characters are characters that do not render visibly on screen but can affect text handling. Common examples include:
- ASCII control characters: NULL (0x00), BEL (0x07), ESC (0x1B)
- Whitespace characters like zero-width spaces
- Line and tab characters, which can be optionally removed
- Formatting marks from PDFs, Word documents, or web content
How the Tool Works
Paste your text into the input box. The tool will automatically detect and remove all non-printable characters. You can also choose to remove tabs and newlines if you want a completely clean, single-line output. The cleaned text is displayed instantly in the output box, ready to copy or download.
