How to use: URL Encode

URL Encode is a free online Encoding Tools tool that encodes problematic characters into percent-encoding, a format supported by URIs/URLs. e.g. = becomes %3d instantly in your browser. Paste your data, adjust the options and get the result in real time — no installation, no sign-up, and nothing is ever uploaded to a server.

FAQ

What is URL Encode?

URL Encode encodes problematic characters into percent-encoding, a format supported by URIs/URLs. e.g. = becomes %3d. It runs entirely in your browser, so your data stays private.

Is URL Encode free to use?

Yes. URL Encode is free, unlimited and works without registration or installation.

Does my data get uploaded?

No. All processing happens locally in your browser; nothing is sent to any server.

Good to know

  • Everything runs client-side, so extremely large inputs are limited by your browser tab’s memory rather than by a server upload limit.
  • The worked example below could not be pre-computed for this tool (threw: function is not iterable (cannot read property Symbol(Symbol.iterator))); the interactive tool above still works normally.
