Why do URLs need encoding?
URLs must encode reserved characters such as spaces, ampersands, question marks, and non-ASCII text so browsers and servers interpret them correctly.
URL Encoder/Decoder
Encode or decode URL strings, query parameters, and percent-encoded values for browser, API, and redirect workflows.
About URL Encoder/Decoder
Encode and Decode URL Strings Safely
The URL Encoder and Decoder converts reserved characters into URL-safe encoding and restores encoded strings back into readable text when needed.
Use it when working with query strings, redirects, callback URLs, tracking parameters, or encoded values copied from browsers, APIs, or logs.
Common Uses
- Encode query parameters before sending data through links or redirects.
- Decode percent-encoded URLs for debugging and inspection.
- Check how special characters, spaces, and non-ASCII text are represented in URLs.
How to use URL Encoder/Decoder
How To Use the URL Encoder and Decoder
- Paste a plain text URL fragment or an encoded URL value into the input panel.
- Choose encode or decode mode depending on the source text.
- Copy the processed value and use it in your browser, code, redirects, or API requests.
Best Practices
- Encode only the parts of a URL that need it, such as query values.
- Decode copied URLs when debugging so you can read the underlying parameters clearly.
- Be careful not to double-encode values that are already safe.
URL Encoder/Decoder FAQ
What is the difference between URL encoding and decoding?
Encoding converts plain text into percent-encoded characters, while decoding restores those encoded characters back to human-readable text.
