Frequently Asked Questions
URLs can only contain characters from the standard US-ASCII set. Special characters, spaces, and non-ASCII letters must be converted to avoid confusing web browsers and servers.
Percent-encoding is a mechanism where special characters are replaced by a percent sign (%) followed by their two-digit hexadecimal ASCII representation (e.g., a space becomes %20).
No. URL encoding is only a data format conversion. It does not encrypt data and should never be used to hide sensitive credentials.
Yes, you can paste entire query strings (e.g., key1=value1&key2=value2) to encode or decode parameter values safely.
No. The conversion is performed entirely in your browser using JavaScript. No network traffic is generated, keeping your data confidential.
Spaces are typically encoded as '%20' in standard URIs, or sometimes as a plus sign (+) in application/x-www-form-urlencoded query strings.
Yes, our tool uses UTF-8 byte representation before percent-encoding, supporting Turkish, Arabic, Chinese, emojis, and all international symbols.
If you try to decode a URL containing malformed percent sequences (like a single % not followed by hex digits), decoding will fail.
Our converter handles extremely long URLs. However, web browsers and servers typically limit URLs to around 2048 characters.
Yes. The PWA caching architecture enables all URL encoding and decoding operations to run without an active internet connection.
