URL Encoder Online — Encode Special Characters in URLs Instantly
URLs can only contain certain characters. Spaces, ampersands, question marks, hash symbols — all of these have special meaning in a URL or will simply break it. When your URL contains any of these characters, you need to encode them first.
The URL Encoder converts any string into a safe, percent-encoded URL format instantly.
What Is URL Encoding?
URL encoding (also called percent encoding) replaces unsafe characters with a % followed by two hexadecimal digits representing the character's ASCII code.
For example:
- Space becomes
%20 &becomes%26=becomes%3D#becomes%23+becomes%2B
This ensures the URL is valid and interpreted correctly by browsers and servers.
When You Actually Need URL Encoding
Query string parameters — if you're passing a value like name=Rohan Surve in a URL, the space will break the parameter. Encoded: name=Rohan%20Surve.
Search queries in URLs — passing user search input as a URL parameter requires encoding so special characters don't interfere with the URL structure.
API requests — many APIs require encoded parameters in the request URL. Sending unencoded values causes malformed requests.
Redirect URLs — when passing a return URL as a parameter (like ?redirect=https://rohansurve.in/dashboard), the slashes and colons in the value must be encoded.
Flutter apps — when building HTTP requests in Flutter using Uri.parse() or constructing query parameters manually, encoding special characters correctly prevents request failures.

URL Encoding vs HTML Encoding — What's the Difference?
These are two different things that people often confuse:
- URL encoding converts characters for safe use inside URLs — spaces become
%20,&becomes%26 - HTML encoding converts characters for safe display inside HTML —
<becomes<,&becomes&
Use URL encoding for links, query strings, and API calls. Use HTML encoding for displaying text inside web pages.
Both tools are available on this site — URL Encoder and HTML Encoder.
