What URL-encode a List Tool Can Do:

  • Encode each line of a list using encodeURIComponent
  • Convert spaces to + optionally (for application/x-www-form-urlencoded)
  • Trim lines and ignore empty entries
  • Show a live output count and flash effect on updates
  • Supports file imports like .txt, .csv, .json, etc.

Example:

apple pie
banana & cream

Output:

banana%20%26%20cream

Or with “Use + for space”:

apple+pie
banana+%26+cream

Common Use Cases:

Use this tool to safely prepare URL parameters, encode values for APIs or redirects, or sanitize user input for query strings. Great for handling structured input lists that need individual encoding.

Useful Tools & Suggestions:

If you’re URL-encoding a list, try Normalize List Item Separators first to make sure each item is clearly separated before the conversion. Then, once everything’s encoded, Join List Items helps you flatten the output into a clean string for use in links, APIs, or query parameters. As a result, your data stays well-structured and ready for action no guesswork needed.
