Encode and Decode URL Text
Convert spaces, Unicode characters, symbols, and reserved characters into URL-safe encoding, or decode percent-encoded strings back into readable text.
Where URL Encoding Matters
Use encoding for query strings, redirect URLs, form data, tracking parameters, API requests, and links that contain spaces, punctuation, or non-Latin characters.
Check Before Sharing Links
Decoded text can reveal hidden parameters or unsafe destinations. Review URLs before opening or sharing, especially when links include redirects, tokens, or tracking values.
About This Tool
URL Encoder converts text into percent-encoded URL format and decodes percent-encoded strings back to readable text. It is essential for developers building query strings, working with API parameters, or handling special characters in URLs.
When to Use It
Use this when constructing a URL that contains spaces, ampersands, or non-ASCII characters, when debugging a malformed URL in a server log, or when encoding a parameter value before appending it to a query string.
How to Use
- Select Encode or Decode mode.
- Paste your URL or parameter value into the input field.
- Click Convert to produce the encoded or decoded output.
- Copy the result and use it in your request or application.
Frequently Asked Questions
What characters need to be URL encoded?
Spaces, special characters such as & # = + ? /, and non-ASCII characters including accented letters and emoji all need to be percent-encoded in a URL.
What is the difference between encodeURI and encodeURIComponent?
encodeURI encodes a full URL and leaves structural characters like / and ? intact. encodeURIComponent encodes a single parameter value and escapes those structural characters too.
Should I encode the entire URL or just the parameter values?
Encode only the parameter values, not the full URL. Encoding the entire URL will break the structural characters that define the URL format.
