URL-encode Unicode
Convert Unicode to URL-Safe Format Instantly
Adding spaces, emojis, or foreign characters to a web address often breaks the link or results in a 404 error. This tool acts as a bridge, re-encoding your text into standard Percent-Encoded strings compatible with the HTTP Protocol and modern browsers.
How to Encode URLs
-
Enter Text: Paste your query parameters, full URL, or text containing symbols (like
&,?, or Emojis). - Process: The algorithm iterates through your string, detecting unsafe characters that violate ASCII standards.
- Copy & Link: Click copy. Your string is now safe to use in GET Requests, APIs, or HTML links.
https://...), be careful not to encode the protocol slashes (://). Use encodeURI for full links and encodeURIComponent for specific query values.
Why Direct Copy-Paste Fails
The internet’s address system relies on the **ASCII** character set. Characters like spaces, emojis, or non-Latin scripts (e.g., Arabic or Chinese) have no direct representation in the valid set of URL characters defined by **RFC 3986**.
If you put a space in a URL, the browser cuts off the request at that point. To fix this, we must perform **Percent-Encoding**. This converts the character into its UTF-8 byte value, represented as hexadecimal digits preceded by a `%`. For example, a space becomes `%20` and an emoji like `😀` becomes `%F0%9F%98%80`.
Manual vs. Automated Conversion
| Comparison | Manual Replacement | Our URL Encoder |
|---|---|---|
| Accuracy | High risk of missing reserved chars | 100% RFC 3986 Compliant |
| Complexity | Requires looking up Hex tables | Instant Automated Mapping |
| Data Safety | Formatting errors break links | Ensures valid HTTP requests |
Frequently Asked Questions
Q. What is the difference between encodeURI and encodeURIComponent?
encodeURI assumes you are inputting a full URL and does not encode reserved characters like :, /, or ?. encodeURIComponent assumes you are inputting a specific value (like a username) and encodes everything including slashes.
Q. Why does my text turn into % signs?
This is called Percent-Encoding. The computer translates the unsafe character into safe Hexadecimal bytes so servers can read it without errors. For example, a blank space is universally read as %20.
