URL Encoder
Encode text to URL-safe format. Convert special characters to percent-encoded format for safe transmission in URLs.
About URL Encoding
URL encoding (also known as percent encoding) converts characters into a format that can be safely transmitted in URLs.
Characters encoded: Spaces become %20, special characters like &, #, ?, etc. are converted to their percent-encoded equivalents.
Use cases: Query parameters, form data, file names in URLs, and any text that needs to be URL-safe.
Security: All processing happens locally in your browser. No data is sent to our servers.

🔗 URL Encoding (Percent-Encoding) Explained
URL encoding (percent-encoding) converts characters that are not safe inside a URL into a standardized format. This prevents broken links, malformed query strings, and subtle bugs when passing user input through URLs.
A URL has reserved characters that carry meaning (like &, ?, #). If you place them inside a parameter value without encoding, the browser/server may interpret them as separators rather than data.
Example: the text Hello & Welcome becomes Hello%20%26%20Welcome, so it can be safely used as a query parameter value.
How to use this tool
- Paste the parameter value (or text) you want to encode.
- Copy the encoded result into your URL or API request.
- Avoid double-encoding already-encoded strings.
