URL Encoder & Decoder

URL encoding (also called percent encoding) converts special characters into a format that can be transmitted over the internet. URLs can only contain certain characters from the ASCII set. Characters like spaces, ampersands, or special symbols need to be encoded into percent-encoded format (e.g., space becomes %20). This ensures URLs are valid and can be properly interpreted by web browsers and servers.

Simply paste your text into the input field. For encoding, enter your plain text and it will be converted to URL-safe format. For decoding, paste a URL-encoded string and it will be converted back to readable text. The tool also supports Base64 encoding and decoding. Results appear instantly as you type, and you can copy the output with one click.

URL encoding (percent encoding) is specifically designed to make text safe for URLs by replacing special characters with %XX codes. Base64 encoding converts binary data or text into ASCII characters using a 64-character alphabet. While both make data transmission-safe, Base64 is often used for encoding binary data (like images) or credentials, while URL encoding is used specifically for URLs and query parameters.

Yes. All encoding and decoding happens directly in your browser using JavaScript. No data is sent to any server, meaning your sensitive information never leaves your device. This makes it safe to use for encoding passwords, API keys, or other confidential data.
