Encode URLs safely for use in browsers, APIs, and query strings. Full UTF-8 support for international characters.
Type or paste the text you want to encode into the input field above.
The tool automatically encodes your text in real-time as you type.
Click the copy button to save the encoded URL to your clipboard.
Properly encodes special characters to ensure URLs work correctly across all browsers and systems.
Full support for encoding international characters, including Chinese, Japanese, Arabic, and emojis.
Handles query parameters, form data, and path segments with proper percent-encoding.
All encoding happens in your browser. Your data never leaves your device.
URL encoding (also called percent-encoding) replaces unsafe ASCII characters with a percent sign (%) followed by two hexadecimal digits. This ensures that data can be safely transmitted in URLs without breaking the URL structure.
Characters like spaces, ampersands (&), equals signs (=), and non-ASCII characters must be encoded. For example, a space becomes %20, and the text "hello world" becomes hello%20world.
Encode values before adding them to URL query strings to prevent parsing errors.
Safely encode data when making HTTP requests to APIs and web services.
Encode form inputs that contain special characters before submission.
Create properly encoded deep links for mobile apps and web applications.
URL encoding (also known as percent-encoding) is the process of converting characters into a format that can be safely transmitted in URLs. Special characters are replaced with a percent sign (%) followed by two hexadecimal digits representing the character's ASCII value. For example, a space becomes %20, and an ampersand (&) becomes %26.
Simply type or paste your text into the input field at the top of this page. Our tool automatically encodes the text in real-time as you type, showing the encoded result instantly. You can then copy the encoded URL with one click. No registration, payment, or software installation required.
Characters that need URL encoding include spaces, special characters like &, =, ?, #, %, and any non-ASCII characters such as international text (Chinese, Arabic, emojis, etc.). Reserved characters that have special meaning in URLs must also be encoded when used as data values.
Use URL encoding when adding data to query parameters, creating API requests, submitting form data with special characters, or generating deep links. Encoding ensures your data is safely transmitted without breaking the URL structure or causing parsing errors.
