Not every character belongs in a browser's address bar. Characters like spaces, brackets, and symbols can confuse servers and break your links. Our Free URL Encoder Decoder allows you to instantly transform "unsafe" text into a standardized percent-encoded format or reverse the process to read complex data strings. Ensure your API calls and web links are 100% compliant with internet protocols.
Browser Compatibility: Browsers have a limited set of characters they can process. Encoding converts forbidden characters into a "Percent (%)" followed by their hexadecimal value.
API & Database Safety: When sending data through a URL (GET requests), encoding prevents special characters from being misinterpreted as command separators (like & or =).
SEO-Friendly Links: While clean URLs are best, sometimes tracking parameters or search queries require special characters. Encoding ensures these links remain functional for crawlers.
Security: Properly encoding user-generated content in a URL helps prevent certain types of injection attacks and data corruption.
Paste Your Text: Enter the URL or string of text into the input box.
Choose Your Action:
Encode: Turn special characters into percent-encoded strings (e.g., " " becomes "%20").
Decode: Turn percent-encoded strings back into human-readable text.
Instant Result: Get your converted string immediately, ready to be used in your code or browser.

Q: What is URL Encoding?
A: URL encoding, also known as Percent-encoding, is a mechanism for encoding information in a Uniform Resource Identifier (URI). Characters that are not allowed are replaced by a percent sign followed by two hexadecimal digits.
Q: Why do spaces turn into %20?
A: In the standard URL specification, spaces are not allowed. %20 is the hexadecimal representation of a space character in the ASCII set.
Q: Does encoding a URL affect my SEO?
A: Not negatively. In fact, ensuring your URLs are properly encoded prevents "Broken Link" errors, which helps search engine bots crawl your site more efficiently.
