Base64 Encoder/Decoder

Base64 Encoder/Decoder converts binary or text data to the Base64 ASCII representation and back. Base64 is widely used to embed images in CSS and HTML, transmit binary data in JSON payloads, and encode credentials in HTTP Basic Auth headers.

Many APIs, configuration files, and data-URI schemes require Base64. Being able to encode or decode inline without installing anything makes debugging much faster.

Tip: If you are encoding binary files such as images or PDFs, make sure the tool handles raw bytes correctly — some Base64 encoders designed for text will corrupt binary data by applying charset conversions.
