Frequently asked questions

How do I remove accents from text?

Are accented letters handled?

Yes, accented letters convert correctly between upper and lower case.

Yes, conversion is instant even for several pages.

Is this tool really free?

When to use it

The case converter fixes text typed in CAPS by mistake, formats headings, prepares variable names (camelCase, snake_case) or creates a clean URL slug for a blog post.

Our tips

💡 “Sentence case” capitalises only the start of sentences.
💡 The slug removes accents and special characters for a URL-friendly result.
💡 Avoid all-caps headings — they read as shouting.
