Should I paste a complete URL?
Use this tool for a value, path segment or other URL component. Encoding a full URL also encodes its separators.
Tools
URL Encode / Decode
Encode and decode URL-safe strings, paths, and query values.
Encode or decode a text value with the browser’s encodeURIComponent and decodeURIComponent functions.
How to use this tool
- Paste the text, path segment or query value.
- Select Encode to create a component-encoded value, or Decode to reverse one.
- Check the output before inserting it into a URL.
- Copy the result.
Ways to use it
- Prepare a query value
- Encode a value containing spaces, ampersands or non-ASCII text before placing it after a query parameter.
- Inspect a URL component
- Decode a percent-encoded path segment or query value for troubleshooting.
URL encoding notes
- Encode uses encodeURIComponent on the whole input, so it is intended for one URL component rather than a complete URL you want to preserve as-is.
- Decoding uses decodeURIComponent. A plus sign remains a plus sign; it is not converted to a space.
- Malformed percent escapes cannot be decoded and show an input error.
Common questions
Why is a space shown as %20?
That is the component encoding produced by encodeURIComponent.
Why did + not become a space?
This tool uses decodeURIComponent, which keeps + as a literal plus sign.
Does this send my URL anywhere?
No. The conversion happens in the browser and the page does not save the input.
