Encode and decode URLs instantly. Perfect for making URLs safe for web transmission, handling special characters, and ensuring proper URL formatting.
Supports batch processing, developer options, and multiple encoding modes.
• Full URL Encoding: Preserves URL structure (:, /, ?, #, etc.)
• Component Encoding: Encodes all special characters
• Batch Mode: Process multiple URLs at once
Choose encoding mode using toggle buttons: Encode or Decode URLs
Enter URLs by typing, pasting, or uploading files for batch processing
Configure developer options like full URL encoding or query parameter only encoding
Click encode or decode to process URLs instantly, then copy or download results
Encode form data with special characters like spaces, ampersands, and question marks for safe transmission in URLs
Properly encode URL parameters when building REST APIs or making HTTP requests with special characters
Create clean, properly encoded URLs for websites and ensure search engines can crawl them correctly
Handle URLs with non-ASCII characters, emojis, and international text for global applications
Encode URL parameters and handle special characters in web forms, APIs, and navigation systems
Ensure proper URL formatting when sending data between systems, especially with special characters
Create properly encoded URLs for sharing on social media and ensuring proper link tracking
Handle URLs with Unicode characters, emojis, and non-ASCII text for global user bases
URL encoding (also known as percent encoding) converts special characters into a format that can be safely transmitted over the internet.
Characters like spaces, ampersands, question marks, and other symbols have special meanings in URLs and must be encoded when used as data.
The encoding process replaces unsafe characters with a % followed by two hexadecimal digits representing the character's ASCII value.
Different encoding levels exist: full URL encoding preserves structural characters like :/ while component encoding encodes all special characters.
Double-encoding URLs
Avoid encoding already encoded URLs. Decode first if you're unsure whether a URL is already encoded
Wrong encoding level
Use full URL encoding for complete URLs and component encoding for URL parameters or individual segments
Encoding unnecessary characters
Letters, numbers, and safe characters (-, _, ~, .) don't need encoding. Only encode special characters
Ignoring Unicode characters
International characters and emojis automatically convert to UTF-8 percent encoding for proper transmission
URL encoding is used to safely transmit special characters in URLs, handle query parameters with spaces and symbols, work with international characters in URLs, ensure compatibility across different systems, and prevent URL parsing errors in web applications.
Characters that need encoding include spaces (%20), ampersands (&), question marks (?), equals signs (=), slashes (/), colons (:), and other special characters. Letters (a-z, A-Z), numbers (0-9), and a few special characters (-, _, ~, .) don't need encoding.
encodeURI preserves characters like : / ? # [ ] @ ! $ & ' ( ) * + , ; = that are part of the URL structure, while encodeURIComponent encodes all special characters except letters, numbers, and a few safe characters. Use encodeURI for full URLs and encodeURIComponent for URL parameters.
Yes! Our tool supports batch processing. Simply paste multiple URLs, one per line, and they'll all be encoded or decoded simultaneously. This is perfect for processing lists of URLs from spreadsheets or documents.
Our tool automatically handles UTF-8 encoding, so international characters, emojis, and non-Latin scripts are properly encoded using percent encoding. For example, 'café' becomes 'caf%C3%A9'.
No, they're different. URL encoding (percent encoding) makes URLs safe for transmission by replacing special characters with %XX codes. Base64 converts binary data to ASCII text using a different character set. They serve different purposes.
Yes, absolutely! Our URL encoder/decoder is completely free with no restrictions on personal or commercial use. No registration, API keys, or premium features required.
