About

This utility provides a straightforward way to decode Base64 encoded strings. Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format by translating it into a radix-64 representation. This tool utilizes the `atob()` (ASCII to Binary) JavaScript function to perform the core decoding. For proper handling of various character encodings, especially UTF-8, the decoded binary string is then converted into a `Uint8Array` and subsequently decoded into a human-readable string using the `TextDecoder` API. This client-side implementation ensures data privacy and instant decoding without server interaction.
