Diacritic & Accent Remover

About this tool

The Diacritic & Accent Remover strips diacritical marks — such as accents, umlauts, cedillas, tildes, carons and circumflexes — from text, leaving the base letter. Characters like é become e, ü becomes u, ñ becomes n, ç becomes c and ň becomes n. This is useful when preparing text for systems that struggle with accented input, creating URL slugs, normalizing database records, or matching names that differ only by accents. The tool applies Unicode NFD decomposition and then deletes the combining marks in the U+0300–U+036F block. Letters that are distinct characters rather than a base letter plus a mark, such as ł, ø, đ, æ and ß, are not converted, so the output is not guaranteed to be pure ASCII. The same marks are also removed from Greek and Cyrillic letters (ά → α, й → и).

Why use it

• Strips accents, umlauts, cedillas, tildes and other combining marks from Latin letters in one click.

• Works entirely in your browser — no data is sent to any server.

• Preserves punctuation, spacing, and Chinese, Arabic and Hebrew text untouched.

• Useful for creating URL slugs, filenames, and database-safe strings.

• Uses standard Unicode decomposition, so every precomposed accented letter is handled the same way with no manual mapping.

• Speeds up CSV cleanup, slug generation, and ASCII normalization workflows.

How to use

1. Paste or type your accented text into the Input text box.
2. Click Remove Accents to fill the Output box.
3. After the first conversion, the output keeps updating as you edit the input.
4. Check the Characters and Words counts under the output.
5. Click Copy to copy the de-accented text to your clipboard.
6. Paste the result into your CMS, database, slug field or text editor.

When it helps

• Preparing multilingual text for ASCII-only databases or APIs.
• Converting European names or addresses to slug-friendly format.
• Normalizing CSV data exported from foreign-language systems.
• Generating clean filenames from titles with accented characters.
• Cleaning author or product names for SEO-friendly URL slugs.
• Comparing two strings that differ only by diacritics (search match boost).

Examples

Tips

• Combine this tool with the Slugify tool to go from accented title to URL slug in two steps.
• If you need to keep ß, æ, or ø as-is, those are not combining diacritics and will already pass through unchanged.
• Run accented CSV exports through this tool before importing into legacy systems that fail on UTF-8 input.
• For author indexing, store both the original name and the de-accented version to support fuzzy search matches.
• When generating filenames, also strip remaining special characters with the Slug Generator after de-accenting.

Frequently Asked Questions

Glossary

Diacritic

A small mark added to a letter (acute, grave, umlaut, tilde, cedilla) that modifies its pronunciation or meaning.

NFD (Normalization Form D)

A Unicode normalization form that decomposes pre-combined characters (like é) into a base letter (e) plus a combining mark.

Combining mark

A Unicode character that attaches visually to the preceding base character, used to render diacritics like accents and umlauts.

ASCII

A 7-bit character encoding limited to 128 characters covering English letters, digits, and basic punctuation.

Slug

A URL-friendly identifier consisting of lowercase letters, numbers, and hyphens — typically derived from a title.

Folding

The process of mapping characters to a simpler form for comparison or indexing — often diacritic-folding for search.
