Encryption Tools

URL Encoder / Decoder

UrlEncode and UrlDecode any address, percent-encoding special characters and Chinese text

URL to encode or decode

Encoded / decoded URL

What this does

This tool does two things to a URL: UrlEncode and UrlDecode.

Encoding turns special characters and non-ASCII text into percent-encoded form — https://www.renfei.net/café becomes https%3A%2F%2Fwww.renfei.net%2Fcaf%C3%A9.

Everything runs in the browser. Your input is never uploaded anywhere — encoding and decoding all happen locally.

Good for

Encoding a URL before sharing it, when it contains Chinese or special characters
Decoding percent-encoded parameters returned by an API while debugging
Checking an encoded or decoded URL before you bake it into a script
