URL ENCODER/DECODER
Free URL Encoder and Decoder for Links, Query Strings, and Web Text
This URL Encoder/Decoder helps you convert readable text into URL-safe format and decode encoded URL strings back into readable text. It is useful for links, query parameters, tracking URLs, API requests, search strings, redirects, form values, and everyday web debugging.
URLs can break when they contain spaces, symbols, emojis, or non-English characters that are not encoded correctly. This tool makes those values safer for URLs by using browser-based encoding and decoding functions.
How to Use This URL Encoder/Decoder
- Paste your URL or text. Add the string you want to encode or decode into the text area.
- Click Encode. Use Encode when you need to make text safe for a URL, query string, or parameter.
- Click Decode. Use Decode when you want to turn encoded URL text back into readable text.
- Copy the result. Click Copy Text to move the encoded or decoded result to your clipboard.
- Clear and start again. Use Clear Text when you want to remove the current value and paste a new one.
URL Encoding Example
URL encoding replaces characters that may not be safe inside a URL with percent-encoded values. For example, a space often becomes %20.

Encoded Output
Helpful note: URL encoding is not encryption. It makes text safe for URLs, but it does not protect private information. Do not use URL encoding as a security method for passwords, tokens, or sensitive data.

Best Practices for URL Encoding
- Encode query values: Encode search terms, form values, tracking values, and special characters before placing them in a URL.
- Decode before reviewing: Decode long query strings when you need to understand what a URL contains.
- Do not confuse encoding with security: Encoding makes URLs valid, but it does not hide or protect sensitive information.
- Test important URLs: After encoding or decoding, open important links carefully and confirm they still work as expected.
- Be careful with full URLs: Encoding an entire URL can also encode characters like
:,/, and?. For many workflows, you may only want to encode a parameter value.
