URL Decoder

URLs can only contain a limited set of characters. Spaces, special symbols, non-ASCII characters, and reserved characters like ampersands or equals signs all have to be encoded before they can appear safely in a URL. The result is those percent-encoded strings you've probably seen: %20 for a space, %2F for a forward slash, %40 for an at sign. URL Decoder converts those encoded strings back into readable text.

If you've ever copied a URL from a browser and found it unreadable because of percent-encoding, this tool solves that immediately. Paste the encoded URL in, get the clean readable version out. It's the kind of small friction that interrupts your workflow constantly if you deal with URLs regularly — and it's the kind of thing that should take two seconds to fix.

For developers working with APIs, query strings often contain encoded parameters that need to be decoded to verify the values being passed. Debugging an OAuth callback URL, checking what a form submission is actually sending, or reading the contents of a deeply nested redirect parameter all become much easier when you can decode the URL on demand.

URL encoding and decoding also matters for security. Encoded characters are sometimes used in injection attempts to bypass filters that look for raw characters. Being able to quickly decode a suspicious URL and see its actual content is a basic step in evaluating whether something looks malicious. The decoder handles both standard percent-encoding and plus-sign encoding for spaces, covering the full range of URL formats you're likely to encounter.
