Frequently Asked Questions
What is the difference between encodeURI and encodeURIComponent?
`encodeURI` preserves special protocol characters like `://` and `?`, while `encodeURIComponent` encodes all characters including slashes and ampersands for safe query parameter usage.
Can this tool parse URL query parameters into JSON?
Yes. Switch the Action to 'Parse Query Params (JSON)' to inspect all query keys and values as a structured object.
Does this tool handle '+' as spaces in query strings?
Yes. Decoding automatically handles both `%20` and `+` spaces correctly.
Is my URL sent to any server?
No. All URL encoding and decoding happen 100% locally in your browser memory.
Can I decode non-ASCII and international characters in URLs?
Yes. UTF-8 multi-byte percent-encoded characters are decoded smoothly.
