URL Encode / Decode
Description
The web is built on URLs, but not all characters are safe for the address bar. Spaces, symbols, and
non-ASCII characters can break links or cause security vulnerabilities. The URL Encoder/Decoder tool
ensures your data is transmission-safe. It converts unsafe characters into their "Percent-Encoded"
equivalents (like converting a space to %20). This is a critical utility when building
query strings, debugging form submissions, or handling API parameters.
What It Does
Encodes text to be URL-safe (Percent Encoding) and decodes encoded URLs back to human-readable text.
How To Use
- Mode: Select "Encode" (for data going to a server) or "Decode" (for data coming from a URL).
- Input: Paste your string.
- Result: Copy the safe output string.
Who It Is For
Full-stack developers, SEO specialists, and digital marketers correcting broken links.
Freqently Asked Questions
Why do I see %20?
URLs cannot contain actual spaces. Most browsers replace spaces with %20 (the hex code
for a space) automatically.
What characters are unsafe?
Reserved characters like : / ? # [ ] @ have special meaning in a URL structure. If you
want to use them as data, they must be encoded.
Is this the same as base64?
No. URL encoding (or percent-encoding) is specifically for URI safety. Base64 is for binary data representation.
