Convert special characters, spaces, and symbols into percent-encoded URL parameters so links never break in browsers.
Web addresses cannot contain raw spaces, quotes, ampersands, or hashtags inside query parameters without confusing browsers. Percent-encoding converts characters like spaces into '%20' so web servers receive the exact search query or tracking value you intended.
Worked example: Encode a search query containing spaces and symbols for an API URL
Input
Books & Music #2026 Sale
Expected result
Books%20%26%20Music%20%232026%20Sale
The spaces, ampersand (&), and hashtag (#) are safely encoded so they aren't mistaken for URL delimiters.
Before you use the result
- Encode only the query parameter value, not the entire 'https://' domain prefix.
- Use decoding mode to turn messy percent-encoded URLs back into human-readable text.
- Verify that your link opens properly in an incognito browser window.
If the result is not what you expected
The entire URL got messed up after encoding.
You likely encoded the whole URL including 'https://' and '?', which turned slashes into '%2F'. Only encode the specific value that comes after the equals sign.
