Remove Diacritics Tool (Strip Accents)
Quickly strip accents and diacritics from text, normalize Unicode, and optionally transliterate to ASCII for SEO-friendly slugs, filenames, and clean datasets.
About the Remove Diacritics / Strip Accents Tool
This online text cleaner removes diacritics (accents) from Unicode strings and can normalize text using NFC, NFD, NFKC, or NFKD. It also supports ASCII transliteration for common special letters and developer-friendly options like “keep only ASCII,” punctuation removal, and slug creation for SEO-ready URLs and filenames.
How to Use
- Input: Paste your text, upload a .txt file, or fetch it from a direct URL.
- Choose options: Pick a normalization form, enable “Strip accents,” and toggle “Transliterate to ASCII” if you need plain English letters.
- Developer filters: “Keep only ASCII,” “Remove punctuation,” or “Filename/URL-safe (slugify)” for clean outputs.
- Case: Optionally switch to lower/UPPER/Title/Sentence case.
- Convert: Click Convert to process, then copy the output.
Pro Tips
- NFKD + Strip accents is very effective for removing marks before ASCII-only processing.
- Enable Transliterate to ASCII to map letters like “ß→ss, æ→ae, Ø→O” that aren’t just accents.
- Use Filename/URL-safe to instantly create SEO-friendly slugs from titles.
- Preserve non-Latin scripts keeps Arabic, Chinese, Cyrillic, etc., untouched while cleaning Latin text.
FAQs
Q1: What’s the difference between NFC and NFD?
NFD decomposes characters into base letters + combining marks, which makes accent removal easy; NFC composes them back into single characters. NFKC/NFKD also apply compatibility mappings.
Q2: Is my data uploaded?
No. All processing runs locally in your browser.
Q3: Can it handle large files?
Yes, but performance depends on your device and browser. For very large inputs, paste text or upload a .txt file.
Q4: Why does Fetch from URL sometimes fail?
Remote servers must permit cross-origin requests (CORS). If blocked, download the file and use Upload instead.
