Frequently Asked Questions

What is URL encoding?
URL encoding (percent-encoding) replaces characters that have special meaning in URLs with % followed by their hex code. For example, a space becomes %20, and ? becomes %3F.
When do I need URL encoding?
Whenever you put user input into a URL: query parameters (?name=John%20Doe), path segments with special chars, or building API requests. Also essential for internationalized URLs (CJK text, accented letters).
What is the difference between encodeURI and encodeURIComponent?
encodeURI() preserves URL structure (doesn't encode :/?#). encodeURIComponent() encodes everything, including structural chars — use this for individual query param values.
Does this handle UTF-8?
Yes. Both encodeURIComponent and decodeURIComponent handle UTF-8 correctly. Emojis, CJK characters, accents all round-trip safely.
Is my data private?
Completely. Encoding/decoding runs in your browser using native JavaScript. Neething is sent anywhere.

Why Use URL Encoder / Decoder?

You should try URL Encoder / Decoder for a quick, private way to encode or decode url-safe strings instantly. All processing happens in your browser. Your files and data never leave your device. According to web.dev, client-side processing is the gold standard for privacy.
