About URL Encoder
Percent-encode (URL-encode) text strings so they can be safely included in URLs, query parameters, and form submissions. Special characters such as spaces, &, =, ?, #, and non-ASCII characters are converted to their %XX hexadecimal equivalents. Choose between encodeURIComponent (encodes most special characters) and encodeURI (preserves URI structure characters) depending on your use case. Supports encoding of full URLs or individual query parameter values. The encoded output is displayed in real time as you type. Runs entirely in your browser –no data is transmitted.
Frequently Asked Questions
What is the difference between encodeURI and encodeURIComponent?
encodeURI encodes a full URL, preserving characters like /, ?, &. encodeURIComponent encodes an individual query value, encoding those characters too.
Does URL encoding handle Unicode characters?
Yes. Non-ASCII characters are first converted to UTF-8 bytes and then percent-encoded.
Can I encode an entire URL at once?
Yes. Use encodeURI mode to encode a full URL while preserving its structural characters.
