What this tool does
Remove Accents converts accented and special letters into their plain equivalents — "á" becomes "a," "ñ" becomes "n," "ç" becomes "c" — while leaving the rest of your text unchanged. It strips diacritical marks from any language, turning accented text into clean ASCII-friendly letters in one click.
Why you would remove accents
Many systems still do not handle accented characters well. Usernames, email addresses, file names, URL slugs, database keys and legacy software often require plain unaccented letters. When a name like "José" or a city like "São Paulo" needs to fit one of these systems, removing the accents produces a compatible version. It is also used to normalize text for searching and matching, where "cafe" and "café" should be treated as the same.
How it works
The tool uses Unicode normalization to separate each letter from its accent mark, then removes the marks, leaving the base letter intact. This works across languages — French, Spanish, Portuguese, German, and many others — and handles a wide range of diacritics including acute, grave, circumflex, tilde, umlaut and cedilla. The underlying letters and all other text stay exactly as they were.
When to keep accents
Removing accents is for compatibility, not for display. In any context where the text is read by people — published writing, names shown to users, formal documents — accents are part of correct spelling and should be kept. "São Paulo" and "Sao Paulo" are not equally correct in Portuguese. Use this tool when a system demands plain letters, not as a general cleanup of properly accented text.
When you need to remove accents
Removing accents and diacritics converts letters like á, é, ñ, ç and ü to their plain forms a, e, n, c and u. This is needed whenever a system only accepts basic ASCII letters: generating a username or email from a name, creating a URL slug, preparing data for a legacy database, normalizing search terms so "Jose" matches "José," or producing file names that work across operating systems. The words stay readable — only the diacritical marks are stripped.
How accent removal works
Under the hood, each accented character is decomposed into a base letter plus a combining mark, then the marks are discarded, leaving the base letter. This is why "café" becomes "cafe" and "piñata" becomes "pinata" without changing anything else. It handles accents from many languages — Spanish, Portuguese, French, German and more — in a single pass. Note that some non-Latin scripts do not decompose this way, so the tool is most useful for Latin-based languages.
Accents, search and data matching
A common reason to strip accents is to make search and matching forgiving. If your data stores "São Paulo" but users type "Sao Paulo," normalizing both to the unaccented form lets them match. The same applies to de-duplicating a list where the same name appears with and without accents. Removing accents before comparison turns near-duplicates into exact matches, which is essential for clean data and reliable search.
