Base64 Encoder/Decoder

Convert data between encoded and decoded formats

What is Base64 encoding?

Base64 encoding converts binary or text data into ASCII characters so it can be safely transported in places that expect plain text, such as JSON payloads, HTTP headers, and data URLs. It is an encoding format, not encryption.

How does Base64 decoding help?

Base64 decoding transforms encoded strings back into the original readable text or bytes. This is useful while debugging APIs, inspecting tokens, or handling files represented as Base64 in browser and backend workflows.
