FAQ
What's the difference between Base64URL and standard Base64?
Base64URL replaces characters unsuitable for URLs, making it more suitable for URL parameters, JWT and token scenarios.
Why does JWT often use Base64URL?
Because JWT needs to be safely transmitted in URLs, headers and text environments. Base64URL better reduces special character compatibility issues.
Is it suitable for URL parameters and secure tokens?
Absolutely. Many OAuth, signature parameters and link-type tokens use URL Safe Base64.
Does this tool support bidirectional conversion?
Yes. It can convert standard Base64 to URL Safe format, or restore Base64URL to more common standard encoding representation.
