Frequently Asked Questions
How do I encode a URL with special characters or spaces?
Paste your URL or text into the input field and the tool instantly converts spaces and special characters into percent-encoded format (for example, a space becomes %20).
How do I decode a percent-encoded URL back to normal text?
Switch to decode mode and paste your encoded URL — the tool converts it back to its original, readable text instantly.
What is the difference between encodeURIComponent and encodeURI?
encodeURIComponent encodes all special characters including those used in query strings (like & and =), while encodeURI leaves URL structure characters intact — this tool supports both modes.
Why do I need to encode a URL?
URLs can only contain a limited set of characters safely. Encoding converts spaces, symbols, and non-ASCII characters into a format that can be safely transmitted in a URL or query string.
Is this URL encoder/decoder free to use?
Yes, completely free with no registration and no limits on how many times you can use it.
Does it send my URL or data to a server?
No, all encoding and decoding happens locally in your browser using native JavaScript functions — nothing is transmitted anywhere.
