What is a Base64?
A Base64 Encoder/Decoder converts text strings to and from Base64 encoding — a binary-to-text format that represents binary data as printable ASCII characters. It is commonly used for embedding images in HTML/CSS, encoding API authentication credentials, transmitting binary data in JSON, and email attachments (MIME).
Why use Birhrt Dev Tools?
Most online developer tools upload your data to a server for processing. This exposes your API keys, personal info, and proprietary code to potential leaks. Birhrt Dev Tools is built differently. Every tool here runs entirely in your browser using modern Web APIs. No server-side processing, no storage, and zero data transmission.
