Remove Non-Alphanumeric Characters
Remove non-alphanumeric characters — keep Latin letters, digits & spaces
Quick, atomic tool that removes characters not in the allowed Latin set. Use it to strip punctuation, symbols, emojis and non‑Latin scripts while preserving ASCII letters, digits and a curated set of Latin accented characters. It does not trim spaces.
How it works
The tool removes any character that is not in the allowed set. It is designed for Latin alphabet languages — it preserves letters, digits and space, and a specific list of accented Latin characters. All other characters (punctuation, symbols, emojis, non‑Latin scripts, control/junk characters) are removed.
| Preserved characters | Example characters that are removed |
|---|---|
| ASCII letters: A–Z, a–z | Punctuation & symbols: . , ? ! : ; " ' / \ @ # $ % ^ & * ( ) = + < > | ~ ` _ |
| Digits: 0–9 | Emojis: 😀 ❤️ 👍 |
| Space | Non-Latin scripts: Cyrillic (д), Greek (α), Arabic (ع), Chinese (中) |
| Accented Latin characters (preserved): ā ą á à â ä ç ć č ē ę é è ê ë ğ ı í ì î ï ł ń ň ñ ó ò ô ö ø ř ś š ş ť ú ù û ü ů ý ÿ ź ż ž |
Currency & special glyphs: € £ ¥ ₽ © ® §° |
| Invisible/control characters and other unlisted glyphs |

Tips & chaining tools
- To remove spaces as well after cleaning, run Remove Spaces.
- To remove diacritics instead of preserving them, run Remove Diacritics.
- If you need to trim surrounding whitespace or specific characters first, use Trim (Trim can remove whitespace or any characters you specify).
- Strip HTML before cleaning with HTML Stripper.
- Use Remove Empty Lines and Remove Duplicates to normalize lists before or after cleaning.
- To keep or restore specific symbols (for example
+in phone numbers), use Find and Replace before running this tool.
Tips & edge cases
Emojis and non‑Latin scripts: These are removed by design. This tool targets Latin‑alphabet workflows.
Phone numbers and special symbols: Characters such as +, parentheses, currency symbols and punctuation will be removed — that can change meaning. Pre-process with Find & Replace to protect them if needed.
Punctuation and decimal separators: Removing punctuation can alter numeric formats or contractions. Review results for sensitive data.
Large inputs: Very large text may be limited by browser memory. For bulk processing, consider batching or a local script.
