Frequently Asked Questions
What is URL encoding?
URL encoding (percent encoding) converts special characters into a format safe for URLs. For example, spaces become %20 and ampersands become %26. This ensures URLs are transmitted correctly across the internet.
What is the difference between encode and decode?
Encode converts readable text into percent-encoded URL format (e.g., 'hello world' → 'hello%20world'). Decode reverses this, converting percent-encoded text back to readable form.
Does it handle Unicode characters?
Yes. The tool uses JavaScript's encodeURIComponent and decodeURIComponent, which fully support UTF-8 Unicode characters including non-Latin scripts and emoji.
