❓ Frequently Asked Questions

URL encoding converts special characters in a URL into a format that can be safely transmitted over the internet. This is important because:

  • Some characters have special meanings in URLs (like ? for queries, & for parameters)
  • Spaces and special characters can break URL parsing
  • Non-ASCII characters need to be converted to UTF-8 encoding
  • Ensures compatibility across different browsers and servers

For example, a space becomes %20, and an ampersand (&) becomes %26.

encodeURI() is used to encode entire URLs, but it doesn't encode characters that are part of the URL syntax like :, /, ?, &, =, etc.

encodeURIComponent() encodes everything, including special URL characters. Use this for encoding individual URL components like query parameter values.

Example:
encodeURI("https://example.com/search?q=hello world") = "https://example.com/search?q=hello%20world"
encodeURIComponent("hello world") = "hello%20world"

Use URL encoding when:

  • Your URLs contain spaces or special characters
  • You're passing user input in query parameters
  • Working with non-ASCII characters (Chinese, Arabic, emojis, etc.)
  • Sending form data via GET requests
  • Creating dynamic URLs in JavaScript

Avoid URL encoding for:

  • Complete URLs that are already properly formatted
  • Domain names and protocol parts
  • When working with internal APIs that expect raw data

100% Safe and Private! Our URL encoder/decoder works entirely in your browser:

  • No server processing: All encoding/decoding happens locally on your device
  • No data storage: We don't save, log, or transmit your URLs/text to our servers
  • No tracking: We don't use analytics or tracking on this tool page
  • No cookies: No tracking cookies are set for this tool
  • Local storage only: We only use localStorage to save your last input for convenience (optional)

You can even use this tool offline after the first load!

%20 is the proper URL encoding for a space character.

+ is used in application/x-www-form-urlencoded content (like form submissions), not in the URL path itself.

Best practice:

  • Use %20 in URL paths: /search/hello%20world
  • You can use + in query parameters: ?q=hello+world
  • Most modern browsers and servers handle both, but %20 is more universally correct
  • Our tool automatically uses %20 for proper URL encoding

Multiple URLs: Yes! Simply paste multiple URLs or lines of text, and they will all be processed together in the output.

Large files: While there's no strict limit, we recommend:

  • For optimal performance: Keep under 100,000 characters
  • For very large files: Process in chunks or use desktop software
  • Browser memory: Large files may slow down your browser temporarily

File types supported: You can copy-paste content from .txt, .csv, .json, .xml, and other text-based files. Binary files need to be converted to text first.
