Enter a URL or text to encode

Building an outgoing request's query string, appending a search term with spaces or an email address with a plus sign onto a URL, only needs encoding in one direction, converting reserved characters into their percent-encoded form before the request goes out, with no need for a decode feature at all in that specific moment. This tool encodes URLs and query parameters for safe transmission and proper formatting, focused entirely on that one direction rather than requiring a decode option alongside it.

Useful for encoding a search term or a special character before appending it to an outgoing request's query string, formatting a URL correctly before it gets sent to an API, or preparing a query parameter for safe transmission without needing to decode anything in the same pass.

Quick answers for URL Encoder

What is the difference between the Encode and Decode modes?
Encode mode runs your text through encodeURIComponent to escape special characters like spaces and ampersands for safe use in a URL, while Decode mode runs encoded text through decodeURIComponent to turn it back into readable text.
What happens if I try to decode text that is not validly encoded?
An error message is shown instead of garbled output, since decodeURIComponent throws on malformed percent-encoded sequences rather than guessing at the intended characters.
Can I copy the result directly?
Yes, a Copy button sits above the output box and copies the encoded or decoded text straight to your clipboard.
