Frequently Asked Questions
What is URL encoding?
URL encoding (percent-encoding) replaces special characters with a % sign followed by two hex digits. For example, a space becomes %20. This ensures URLs are valid and can be safely transmitted.
When should I URL-encode text?
URL-encode text when including it in query parameters, form data, or any part of a URL that may contain special characters like spaces, ampersands, or non-ASCII characters.
Does this handle Unicode characters?
Yes. This tool uses JavaScript's encodeURIComponent which fully supports UTF-8 Unicode characters including emojis and non-Latin scripts.
