About this URL Encoder
URL encoding converts characters into a safe ASCII representation so they can be transmitted in URLs. This free online URL Encoder/Decoder helps you quickly convert special characters in URLs to a safe format for web use, or decode encoded URLs back into human-readable text. Whether you’re debugging APIs, fixing broken links, or working with query strings, this tool makes your workflow faster and easier.
About URL Encoding & Decoding
URL Encoding is the process of converting special characters into a
format that can be safely transmitted over the internet. For example, spaces are replaced
with %20. Decoding is the reverse process, converting the encoded values back
into readable text or data.
URL encoding is essential when working with query strings, APIs, and web forms.
Without it, special characters like &, =, or ?
could break URLs or cause data errors.
Why Use a URL Encoder/Decoder?

- 📌 Decode URLs — convert encoded text back into human-readable format.
- 📌 Debug APIs — inspect and fix encoded values in API requests.
- 📌 Prevent Errors — ensure special characters don’t break links or data.
