How URL Encode/Decode works

Percent-encode text for query strings and paths, or decode URL-encoded strings back to plain text. Runs locally in your browser.

  1. 1. Add input. Paste, type, or upload. Use a sample if you just want to see it work.
  2. 2. Run it. Processing happens in the browser.
  3. 3. Copy or download. Take the output and close the tab.
  • Encode a query value
Is this the same as encodeURIComponent?
Yes. Encoding uses encodeURIComponent and decoding uses decodeURIComponent (plus converting + to spaces).
Should I encode a full URL including https://?
Usually encode only query values or path segments — not the entire URL with scheme and host.

ToolBay does not store your input. Close the tab and it is gone. More converters tools.
