URL Encoder / Decoder
Encode or decode URLs instantly. Handles special characters, query strings, and Unicode. Free online URL encoding tool — no signup required.
What is URL Encoding?
URL encoding (percent-encoding) converts special characters into a format that can be transmitted within a URL. Characters like spaces, ampersands, and non-ASCII characters are replaced with percent-encoded equivalents (e.g., space becomes %20).
When to Use URL Encoding
Encode query string parameters, form data, file names with special characters, and any text that will appear in a URL. This ensures the URL is valid and the server interprets each parameter correctly.
FAQ
What is the difference between encodeURI and encodeURIComponent?
This tool uses encodeURIComponent, which encodes all special characters including / ? # & =. Use this for encoding individual parameter values. encodeURI leaves URL-structural characters intact and is meant for encoding full URLs.
Does it support Unicode characters?
Yes. Unicode characters (Japanese, Arabic, emoji, etc.) are fully supported. They are encoded as UTF-8 byte sequences in percent-encoded form.
