URL Encoder / Decoder
Encode or decode URL strings instantly. Safely handle special characters for use in web addresses, query parameters, or API calls. Everything happens in your browser — no data leaves your device.
What is URL Encoding?
URL encoding (also called percent‑encoding) converts characters that are not allowed in a URL into a safe format. For example, a space becomes %20, and a question mark becomes %3F. This ensures that the URL is correctly interpreted by web servers and browsers.
Our tool lets you switch between the original text and its encoded form with a single click. No need to remember complex character codes — just paste and convert.
How to Use the URL Encoder / Decoder
- Enter your text or URL – Paste the string you want to encode or decode into the input box.
- Select the operation – Choose URL Encode to convert special characters into percent‑encoded format, or URL Decode to revert an encoded string back to plain text.
- Click the button – The result appears immediately in the output area.
- Copy or download – Use the copy button to grab the result or save it as a .txt file.
Pro Tip: URL encoding is essential when you pass query parameters that contain spaces, ampersands, or other reserved characters. Always encode dynamic values before appending them to a URL.
