Base64 encode plain text, decode Base64 strings, and inspect Base64Url content when you need to read or transform encoded values.
What URL Encoder / Decoder helps you do

Frequently asked questions
What does URL encoding do?
It replaces unsafe or reserved characters with percent-encoded sequences so the value can travel safely in a URL.
When should I decode a URL?
Decode a URL when you need to read query parameters, redirect values, or copied links from logs and browser tools.
Should I encode an entire URL or just a value?
Most of the time you should encode only the query parameter or fragment value, not the entire URL string.
Is this useful for API testing?
Yes. It is especially useful when building request URLs manually or checking whether a parameter was encoded correctly.
