Frequently Asked Questions

FAQs about URL Decoder

What is URL decoding?

URL decoding converts percent-encoded sequences (like %20) back to their original characters. It is the reverse of URL encoding.

What happens if my input is not valid URL encoding?

If the input contains an invalid percent-encoded sequence (like a lone % not followed by two hex digits), the tool will show an error.

Does this tool decode + as a space?

No. This tool uses decodeURIComponent, which decodes %20 as a space but leaves + as-is. If your string uses + for spaces (HTML form encoding), replace them with %20 first.

Can I decode full URLs?

Yes. Paste the full URL and the tool will decode all percent-encoded sequences while leaving valid URL characters intact.

Is my data safe?

Yes. All decoding happens in your browser with no server communication.
