URL Encoder Decoder - Encode & Decode URLs Online
Encode URLs and special characters to percent-encoded format or decode URL-encoded strings instantly.
Encode (Component): Encodes all special characters including slashes (/)
Encode (URL): Encodes URL but preserves protocol and path structure
What is URL Encoding?
URL encoding (also known as percent encoding) is a method of converting special characters and spaces into a format that is safe for transmission over the internet. Characters that have special meaning in URLs (like spaces, &, =, #, /) are converted to % followed by two hexadecimal digits representing their ASCII or UTF-8 value. This ensures URLs remain valid and unambiguous across all systems and browsers.
Why Use URL Encoding?
URL encoding is essential for web development, especially when working with query parameters, form submissions, and API endpoints. Without proper encoding, special characters can break URLs, cause parsing errors, or create security vulnerabilities. URL encoding ensures reliable data transmission across all web systems.

❓ FAQs
What is URL encoding?
URL encoding converts special characters and spaces into a format safe for transmission over the internet. Each character is replaced by % followed by two hexadecimal digits (e.g., space becomes %20).
Why do URLs need encoding?
URLs can only contain certain ASCII characters. Special characters, spaces, and non-ASCII characters must be encoded to avoid breaking URL parsing and to ensure proper data transmission across systems.
Is this URL encoder free?
Yes. Our online URL encoder and decoder is completely free to use without any limitations or registration required.
Can I encode any text to URL format?
Yes. You can encode any text string, including special characters, spaces, and Unicode characters into URL-safe format.
Can I decode URL-encoded strings?
Yes. You can decode any URL-encoded string back to its original text format using the decoder function.
What characters need URL encoding?
Spaces, special characters like &, =, %, #, /, ?, @, and non-ASCII characters must be encoded. Safe characters include letters, digits, hyphens, underscores, dots, and tildes.
Is my data secure?
Yes. All encoding and decoding happens entirely in your browser. No data is sent to servers or stored anywhere. Your data remains completely private.
Can I use this URL encoder on mobile?
Yes. The URL encoder/decoder is fully responsive and works seamlessly on mobile devices, tablets, and desktops.
What is percent encoding?
Percent encoding is another name for URL encoding. It represents special characters using a percent sign followed by two hexadecimal digits representing the ASCII value.
Can I encode query parameters?
Yes. You can encode individual query parameter values or entire query strings for safe transmission in URLs.
What is UTF-8 encoding in URLs?
UTF-8 encoding in URLs represents Unicode characters using multiple bytes. The encoder uses UTF-8 to safely encode non-ASCII characters like emojis and international characters.
Can I use this for form submissions?
Yes. HTML forms use application/x-www-form-urlencoded format, which is URL encoding. This tool helps encode data for forms and APIs.
How do I encode special characters?
The tool automatically encodes all special characters. Just paste or type your text and click 'Encode URL'. Each special character converts to % followed by hex digits.
Can I copy the encoded/decoded result?
Yes. There's a copy button to easily copy the result to your clipboard with one click.
Which browsers support this URL encoder?
The URL encoder/decoder works on Chrome, Firefox, Safari, Edge, and all modern browsers with JavaScript support.
