Concept

Use URL decoding to reveal actual link destinations

URL Decoder restores percent-encoded characters so you can quickly inspect the real path, query parameters, and redirect target of a shared link.

Browsers pass non-ASCII and special characters as `%` + two-digit hex like `%ED%95%9C`, and decoding converts them back to readable text.

Results can differ when you decode the full URL versus a single parameter value, which is important when checking tracking links or redirect parameters.

Before opening a decoded link, verify the scheme, host, and whether any query key changes navigation behavior.

When to use it

Use this tool to inspect shortened links, campaign URLs, and encoded query values before using or sharing them.

Percent decoding

Values like `%ED%95%9C` are restored to `한`, and encoded spaces/symbols become readable plain text.

Safety check before opening

Confirm protocol (`http/https`), destination domain, and redirect-related parameters; avoid opening unknown URLs with suspicious hosts.

This tool only decodes and displays URLs locally. Open links only after manual verification.

Frequently asked questions

What URL-encoded values does it decode?

It restores percent-encoded strings such as %ED%95%9C and spaces represented with + back to text.

Can I copy the decoded result directly?

Yes. Review the restored URL or text in the result area, then copy it with the copy button.

Why do I see an error?

If the percent encoding is broken or incomplete, browser decoding can fail and the tool may show an error.
