What is UTF-8 encoding?

UTF-8 is a variable-width character encoding that can represent every character in the Unicode character set. It's the dominant encoding for the web and is backward compatible with ASCII.

Why should I check UTF-8 encoding?

Checking UTF-8 encoding ensures your text displays correctly across different systems and browsers. Invalid UTF-8 can cause display issues, data corruption, or security vulnerabilities in web applications.

What types of files can I upload?

You can upload any text-based files including .txt, .html, .css, .js, .json, .xml, .csv, and other plain text formats. The tool reads the file as text to check its encoding.

Does this tool modify my text or files?

No, this is a read-only validation tool. It only analyzes your text or file content to check UTF-8 compliance without making any changes to the original content.
