Base64 Encoder/Decoder: Read the Base64 Inside JWTs and API Payloads

Debugging login issues, you often get a JWT or another Base64-encoded token. To see which fields it carries and when it expires, you need to decode it.

Base64 Encoder/Decoder restores such strings to readable content (a JWT's middle segment is standard Base64), and encodes content back for transport, helping you verify the structure.

It also converts between images and Base64, useful for Base64 images returned by an API or small images carried in a request.

That unreadable string is often obvious once decoded. Bookmark Base64 Encoder/Decoder and make auth debugging easier.
