URL Decoder

Decode a percent-encoded URL or string back into readable text online for free — instant, live, entirely inside your browser.

Overview

What is a URL decoder?

A URL decoder reverses percent-encoding, converting sequences like %20 or %26 back into their original characters — revealing the real, human-readable value that was encoded to travel safely inside a URL.

It's useful for debugging tracking links, redirect parameters, or query strings copied from server logs, with full support for decoding non-ASCII characters back to their original form.

Tips

Best practices to keep in mind

A few things worth knowing about decoding a URL correctly.

Decoding a URL reveals the real, human-readable value behind a percent-encoded string — useful when debugging redirects, tracking links, or query parameters copied from server logs.
Sequences like %20 for a space or %26 for an ampersand are the most common you'll encounter — this decoder converts every percent-encoded byte sequence back into its original character.
If decoding produces unexpected or broken text, the input may already be partially decoded or contain a malformed percent sequence — check for a stray '%' not followed by two valid hex digits.
URLs are sometimes double-encoded by mistake, where '%20' becomes '%2520'. If your decoded output still contains '%' sequences, try decoding it a second time to fully reveal the original text.

FAQs

Frequently asked questions

Have questions about decoding a URL? Here are the most common ones our users ask before getting started.

Is this URL decoder free to use?

Yes, the URL decoder is completely free with no signup, no usage limits, and no watermarks on the output. It runs entirely in your browser, so there are no server costs passed on to you and no account is ever required to decode a string.

Does my text get uploaded to a server?

No. All decoding happens locally in your browser using JavaScript's built-in decodeURIComponent function — your text never leaves your device or gets transmitted anywhere. This makes the tool safe to use with private parameters or tokens.

What does URL decoding actually do?

URL decoding reverses percent-encoding, converting sequences like %20 or %26 back into their original characters — a space or an ampersand, for example. It reveals the real, human-readable value that was encoded to travel safely inside a URL.

Why would I need to decode a URL?

Percent-encoded URLs are common in tracking links, redirect parameters, and server logs, and they can be hard to read at a glance. Decoding them makes the actual destination or parameter value clear, which is especially useful when debugging or auditing links.

What if my decoded text still contains percent signs?

That usually means the original string was double-encoded — encoded twice before you received it. Running the output through the decoder a second time will typically reveal the fully decoded, original text with no remaining percent-encoded sequences.
