Remove Non-ASCII Characters
Strip or replace characters outside the standard ASCII range. Fix compatibility issues with emojis, symbols, and special characters.
ASCII Sanitizer Settings
All characters with Unicode > 127 will be removed.
Why use this? Many legacy systems, database configurations, and older protocols (like some SMS gateways or terminal emulators) only support the 128-character ASCII set.
- ASCII Compliance: This tool is essential when you need to ensure your text doesn't contain any "hidden" or special characters that could break legacy systems or specific file formats.
- Safe Cleaning: Use this to prepare data for CSV exports or systems that don't support UTF-8.
Note: If you want to keep characters but remove accents, use our "Remove Accents" tool instead.
Safe ASCII Sanitizer: Clean Non-Standard Characters Online
Non-ASCII characters like emojis, foreign symbols, and accented letters can cause unexpected errors in legacy databases, terminal emulators, and specific file protocols. Our Online Remove Non-ASCII tool is a dedicated utility to sanitize your text and ensure 100% compatibility with systems that only support the standard 128-character ASCII set. Simply paste your text, and the tool will instantly identify and remove any character with a Unicode value greater than 127. You also have the option to replace these characters with a custom placeholder (like a question mark) rather than deleting them entirely. It's an essential tool for data cleaning, system migrations, and preparing content for narrow-protocol communication channels.
