Base64 Encoder/Decoder

This tool utilizes client-side Web APIs and WebAssembly (where necessary) to process data directly on your device. By executing logic locally, you avoid the latency of round-trip server requests and maintain absolute data privacy.

Common mistakes: Ensure your input strictly follows standard formatting. For encoders/decoders, ensure you aren't passing raw binary inadvertently without proper string encoding. For JWTs, remember that decoding a token does not mean the signature is verified or secure.
