The output is not what I expected.
Recheck the input, selected options and the limitation notes below; preserve the original before trying a destructive cleanup. Not all non-ASCII letters decompose into a base letter plus mark.
Remove Accents Tool
Strip combining accent marks from text while keeping letters, numbers, spacing and case.
What this tool does
The tool applies Unicode NFD normalisation and removes combining diacritical marks. It is useful for accent-insensitive keys and cleanup, but it is not full transliteration: characters such as ß, æ and ø do not automatically become ss, ae or o.
Paste text, remove combining accents and review any non-decomposing letters.
Maximum 500,000 characters: 0 / 500000
No result
How to use it
Paste the text whose combining accent marks you want to remove.
Review letters that do not decompose under Unicode NFD.
Copy the cleaned result or continue with case and punctuation cleanup.
Key features
- Unicode NFD normalisation.
- Removal of combining diacritical marks.
- Preservation of original letter case.
Practical use cases
- Preparing accent-insensitive search or comparison keys.
- Cleaning imported names for a controlled matching workflow.
- Creating an intermediate step before a separately defined slug process.
Limitations and important notes
- Not all non-ASCII letters decompose into a base letter plus mark.
- This is not language-aware transliteration.
- The transformation runs in this browser component without an AppKiro conversion API call.
Troubleshooting
The page becomes slow with a large input or repeat count.
Reduce the input, split the operation into smaller batches and close other memory-heavy tabs. Keep an original copy before retrying.
The result changes after I paste it elsewhere.
Test the destination app, font and character encoding. Some apps normalize whitespace or render Unicode differently.
Frequently asked questions
How do I remove accents from text?
The tool applies Unicode NFD normalisation and removes combining diacritical marks. It is useful for accent-insensitive keys and cleanup, but it is not full transliteration: characters such as ß, æ and ø do not automatically become ss, ae or o.
Why does ø or ß remain?
Those characters do not decompose into the expected ASCII sequence under NFD, so full transliteration needs a separate mapping.
Will Vietnamese text become plain ASCII?
Many combining marks are removed, but characters such as đ require separate transliteration. Do not promise complete ASCII output without tests.
What are the limitations?
Not all non-ASCII letters decompose into a base letter plus mark. This is not language-aware transliteration. The transformation runs in this browser component without an AppKiro conversion API call.
