Encode query values and URL fragments safely, or decode percent-encoded text back into readable form.

Output Percent encoding

Encode parameter values, not the whole request syntax, to avoid double encoding.

Is this URL encoder free?

Yes.

What is URL encoding used for?

It makes spaces, symbols, and reserved characters safe to send inside URLs and query parameters.

Is my URL data uploaded?

No. The conversion happens locally.

Why am I seeing %20 and %2F?

Those are encoded representations of characters such as spaces and slashes.

Reserved characters can break a request or quietly change what a parameter means if they're not encoded properly.

This matters most when you're nesting URLs, passing JSON in a query string, or trying to preserve spaces and symbols.

In most cases you only want to encode the value, not the whole URL including `?`, `&`, and `=`.

That keeps the URL readable and saves you from accidental double encoding.

Encode text as Base64URL or decode URL-safe Base64 back to UTF-8 text.
