Why use URL Encoder/Decoder?

Encode text for safe use in a URL, or decode a percent-encoded string back into readable characters. Spaces become %20, & becomes %26 and accented or non-Latin characters are encoded as their UTF-8 bytes.

Decoding is the more common need day to day: tracking links, redirect chains and analytics reports are full of encoded URLs that are hard to read. Paste one here and the original address, including any nested URL, becomes legible again.

Key Benefits

Two-way conversion

Encoding for building links, decoding for reading them.

Nested URLs made readable

Redirect parameters that contain another encoded URL decode back into a normal address.

Runs in the browser

Campaign links and internal URLs are not sent anywhere.

URL Encoder/Decoder FAQs

Why do URLs contain characters like %20 and %3A?

Only a limited set of characters is allowed in a URL. Everything else is replaced by a percent sign and the character's byte value, so %20 is a space and %3A is a colon.
