Frequently Asked Questions

What is URL encoding and why do I need it?

URL encoding converts special characters into a format safe for transmission in URLs. Characters like spaces, ampersands, and slashes are replaced with percent signs followed by hexadecimal values.

Is URL Encoder free to use?

Yes, it's completely free with no signup and no limits.

Can I decode URLs too?

Yes, the "Decode" button converts percent-encoded text back to its readable form; invalid encoded input shows an error message instead of crashing.

Which characters get encoded?

Spaces, accented letters, symbols, and reserved characters like &, ?, #, and / are encoded. Letters, numbers, hyphens, underscores, periods, and tildes are left unchanged, matching the standard encodeURIComponent behavior.

Tips & Tricks

  • Encode query parameter values individually before building a URL, so characters like & or = inside a value don't break the URL structure.
  • If "Decode" shows "Invalid URL encoding," the input contains a malformed percent sequence — double check it was copied completely.
  • Test your encoded URL in a browser address bar to confirm it resolves to the correct destination.
  • Keep the original, unencoded text handy for reference before re-encoding after edits.
