What the URL Encoder/Decoder Does and Why It Matters
The URL Encoder/Decoder converts text to and from percent-encoded form, so characters that are unsafe in a URL — spaces, &, ?, =, and non-ASCII characters — become safe %XX sequences (and back), all in your browser.
This matters because URLs have a strict character set: a raw space or ampersand in a query string breaks the link or splits a parameter. Percent-encoding lets you safely put arbitrary text into a URL or read an encoded link someone shared.
How to Use URL Encoder/Decoder
Paste the text or URL component into the input.
Choose to encode (text to percent-encoding) or decode (percent-encoding back to text).
Run the conversion.
Copy the encoded or decoded result.
Supported Inputs and Limitations
What you provide
Text or a URL component to encode, or a percent-encoded string to decode
What you get
A correctly percent-encoded string (or the decoded text)
Copy-ready output
Known limitations
Encoding a whole URL vs. a single query value differs; encode components individually when building a URL.
Double-encoding (encoding already-encoded text) produces literal %25 sequences — decode first if unsure.
It transforms text; it does not validate that a URL is reachable.
Privacy and Security
Encoding and decoding run entirely in your browser. The text you enter is processed on your device and is never sent to NovaTools or any external service.
Frequently Asked Questions
What is percent-encoding?
It replaces characters that are unsafe in a URL with a % followed by their hex code, for example a space becomes %20, so the URL stays valid.
Should I encode the whole URL?
Usually encode individual components (like a query value) rather than the entire URL, so structural characters such as ? and & are not escaped.
Is my text uploaded?
No. Conversion is local and the text never leaves your browser.
Our free URL Encoder/Decoder tool helps you convert text to and from URL-safe format using percent encoding. This is essential for web development when handling special characters in URLs, query strings, and form data.
How to Use
Type or paste your text into the input area above.
Choose between Full URL Mode (preserves URL structure) or Component Mode (encodes everything for query parameters).
Click Encode URL to convert special characters to percent-encoded format.
Click Decode URL to convert percent-encoded text back to readable format.
Use Copy Result to copy the output to your clipboard.
Click Clear to reset both fields.
Encoding Modes Explained
Full URL Mode: Use this when encoding complete URLs. Preserves URL structure characters like : / ? # [ ] @ as they have special meaning in URLs. Component Mode: Use this for encoding query parameter values or path segments. Encodes all special characters including those reserved for URL structure.
Common Use Cases
Query Parameters: Convert "hello world" to "hello%20world" for use in URLs. Special Characters: Encode symbols, spaces, and non-ASCII characters for web compatibility. API Requests: Properly format data for GET requests and REST APIs. Debugging: Decode encoded URLs to read and understand their structure.
Frequently Asked Questions
Is my data sent to a server?
No. All encoding and decoding happens entirely within your browser. Your text is never transmitted to our servers or stored anywhere.
What's the difference between encodeURI and encodeURIComponent?
encodeURI is designed for full URLs and preserves characters with structural meaning (: / ? # etc.). encodeURIComponent is for individual URL components and encodes all special characters.
What characters get encoded?
Characters outside the unreserved set (A-Z, a-z, 0-9, -, _, ., ~) are encoded as %XX where XX is the hexadecimal value. Spaces become %20 or + in form data.
Can I decode any percent-encoded string?
Yes, as long as the encoding follows the standard format (%XX where XX are valid hex digits). Malformed encoded sequences will be preserved as-is.
Does this handle Unicode characters?
Yes! Modern browsers encode Unicode characters using UTF-8 multi-byte sequences. For example, "Ç" becomes "%C3%87".
