URL Encoder & Decoder
Encode or decode URLs, query parameters, UTM values, and special characters without sending anything to a server.
Safer links and cleaner query strings
URLs break the moment a reserved character lands in the wrong place — an unescaped space, ampersand, or accented
letter can truncate a link, split a query string, or silently drop a parameter. This tool converts that text into
safe percent-encoded form, and decodes existing %20-style links back into readable text so you can see
what a URL actually contains.
The distinction that trips people up is component vs. full URL. Use Encode Component for
individual values — a search term, a UTM tag, a single path segment — where every reserved character must be
escaped. Use Encode URL when you want to preserve the structural characters like
: / ? & that separate the parts of a complete address.
Private and instant
Encoding and decoding use your browser's standard functions and run entirely on your device — handy for UTM campaign values, API request testing, and debugging percent-encoded links without pasting sensitive URLs into an online service.
Frequently Asked Questions
What is URL encoding?
URL encoding converts spaces, punctuation, and special characters into percent-encoded sequences that are safe to use inside URLs.
Should I encode a full URL or just a query value?
Use Encode Component for query values, UTM values, and path pieces. Use Encode URL when you want to preserve normal URL separators like : / ? &.
Does this tool send URLs anywhere?
No. Encoding and decoding use standard browser JavaScript functions and happen entirely on your device.
