NexoraStack Tools
URL Encoder Decoder
Encode URL parameters and decode percent-encoded strings like %20, %2F, and %3D instantly. Useful for query strings, redirects, APIs, and callback URLs.
Tool Interface
Functional explanation
Encodes reserved URL characters and decodes encoded URL fragments safely.
- Prepare query values containing special characters.
- Inspect encoded strings in redirect/debug workflows.
- Ensure consistent encoding across client and server.
How to use
Paste a full URL, query parameter, or encoded string and convert it instantly in your browser. This page is designed for API requests, redirect debugging, and callback parameter troubleshooting.
- Select Encode to convert text into percent-encoded format or Decode to restore readable text.
- Paste a full URL, query string, or encoded value like %20 or %3D.
- Copy the result for use in APIs, redirects, or debugging workflows.
Example
Input
name=Nexora Stack&city=Shenzhen
Output
name%3DNexora%20Stack%26city%3DShenzhen
Encode value segments carefully to avoid double encoding.
Common mistakes
- Double-encoding already encoded values.
- Encoding entire URL where only part needs encoding.
Output interpretation tips
- Percent sequences represent encoded bytes.
- Decode before log comparison when troubleshooting mismatch issues.
Security and privacy notes
- Encoding improves transport safety for URL values, but it is not encryption.
- Use local browser tools when debugging callback URLs or signed request parameters.
FAQ
What is the difference between encodeURI and encodeURIComponent?
encodeURI keeps URL structure intact, while encodeURIComponent encodes all special characters, making it safer for query parameter values.
Why do spaces become %20 in URLs?
URLs use percent-encoding to represent special characters. A space is encoded as %20 in standard URL encoding.
Should I encode the full URL or only query parameters?
Usually only query parameter values should be encoded. Encoding the full URL may break its structure.
Does this tool support UTF-8 encoding?
Yes. The encoder follows standard UTF-8 percent-encoding used in modern browsers and APIs.
Is my data sent to a server?
No. All encoding and decoding happens locally in your browser.
Should I use this for full URLs or just query values?
In most cases you should encode only query parameter values. Encoding the full URL can escape structural characters that should remain readable.
