Free Online URL Encoder / Decoder
The URL Encoder/Decoder is an essential online tool for web developers, digital marketers, and anyone who works with URLs containing special characters. URLs can only contain a limited set of ASCII characters, and any character outside this set â including spaces, symbols, and non-English letters â must be encoded to ensure safe transmission over the internet. This tool uses percent-encoding (also known as URL encoding) to convert special characters into a format that web servers and browsers can process correctly. Simply paste your URL or text into the input field, choose whether to encode or decode, and the result appears instantly. The tool handles all standard encoding schemes and supports UTF-8 characters, making it suitable for international URLs and multilingual content. Whether you are building API endpoints, constructing query strings, debugging redirect issues, or decoding encoded URLs from log files, this tool provides a fast, accurate, and private solution. Everything runs locally in your browser â no data is sent to any server.
How to Use
Using the URL Encoder/Decoder is straightforward. Open the tool page and paste the URL or text you want to process into the input field. Choose the operation: click Encode to convert special characters into percent-encoded format, or click Decode to convert encoded characters back to their original form. The result is displayed instantly in the output field. Use the Copy button to copy the result to your clipboard. For encoding, the tool converts spaces to %20 or + signs, and special characters like &, =, ?, and # are converted to their percent-encoded equivalents. For decoding, the tool reverses this process, restoring the original characters. The tool supports UTF-8 encoding, so it handles international characters, emoji, and non-Latin scripts correctly. You can perform unlimited encode and decode operations without any restrictions, and everything runs locally in your browser for maximum privacy.

Common Use Cases
The URL Encoder/Decoder is essential for web developers constructing API query strings, digital marketers working with tracking URLs and UTM parameters, SEO specialists debugging encoded URLs in redirect chains, and system administrators parsing encoded URLs from server log files. It is also useful for app developers handling deep links and for anyone working with internationalized domain names containing non-ASCII characters.
Tips & Tricks
When encoding URLs for API calls, encode only the parameter values, not the entire URL structure. Double-encoding can cause issues â always verify that your URL has not already been encoded before encoding it again. When decoding, check the result for broken characters if the original encoding was not UTF-8.
