How to encode and decode URLs online
When links contain spaces, symbols, or special characters, URL encoding keeps them safe and predictable. When debugging or inspecting parameters, decoding makes those values readable again. Knowing when to switch between the two makes link handling much easier.
Why URL encoding and decoding are common tasks
URL encoding makes reserved characters and spaces safe for links and query strings.
Decoding helps you inspect parameters that would otherwise be hard to read.
It is useful for frontend work, backend debugging, testing, and analytics links.
A practical workflow
Step 1
Paste the raw URL or encoded string into the input area and identify whether the current task is encoding or decoding.
Step 2
Use encode mode when you need a safe query string, and decode mode when you want to inspect an already encoded value.
Step 3
Run the conversion and verify that special characters, spaces, and separators now match the expected output.
Step 4
Copy the final result back into your app, API request, browser address bar, or test tool.

When should I encode a URL?
Encode a URL when query parameters include spaces, symbols, non-ASCII text, or values that could break the link structure.
Why does decoding sometimes fail?
Decoding usually fails when the input is incomplete, malformed, or not valid percent-encoded text.
Is URL encoding the same as Base64?
No. URL encoding is for making text safe in URLs, while Base64 is a separate text encoding format with different use cases.
