—About this tool
Remove Vietnamese Accents converts diacritic-heavy text into plain ASCII. Vietnamese uses marks like the ones in "Nguyễn" or "Đà Nẵng", which break file names, usernames and URLs on systems that only expect basic Latin letters.
The tool also produces UPPERCASE output and clean, SEO-friendly URL slugs. It is handy for generating consistent identifiers, search keys and links from names, titles and product descriptions.
How to use
- Type or paste your Vietnamese text into the input area.
- The unaccented version appears instantly next to your input.
- Choose the output you need: plain lowercase, UPPERCASE, or a URL slug.
- For slugs, the tool lowercases text, replaces spaces with hyphens and strips punctuation.
- Copy the result and paste it into your file name, username or link.
Features
- Correctly maps every Vietnamese accented vowel and the letter đ/Đ to its ASCII base.
- One-click URL slug generation with hyphen separators and no special characters.
- UPPERCASE conversion for codes and identifiers.
- Preserves the original word order and spacing where relevant.
- Instant conversion as you type — no submit step.
- Also strips diacritics from other Latin-based languages such as French or Spanish.
Frequently asked questions
Does the tool upload my text anywhere?
No. The conversion runs entirely in your browser, so your names, titles and any personal text never leave your device.
How does it handle the letter đ?
The lowercase đ and uppercase Đ are mapped to d and D respectively, since they have no direct accent-free Unicode form.
What makes a slug SEO-friendly?
A slug is lowercase, uses hyphens instead of spaces and contains only letters, numbers and hyphens — the format search engines and web servers handle most reliably.
Will it work on French or German text?
Yes. Common Latin diacritics such as é, ü, ñ and ç are also reduced to their base letters.
Can I convert a whole list at once?
Yes. Paste multiple lines and each line is converted, so you can process many names or titles in one go.
