Privacy First: All encoding/decoding happens in your browser. No data is uploaded to any server.
Base64 is an encoding scheme that converts binary data into text format using 64 safe ASCII characters. It's commonly used for transmitting binary data over text-only systems like email and JSON.
Base64 encoding is useful for embedding images in HTML/CSS, transmitting binary data via email, storing sensitive data, and ensuring data integrity across different systems and platforms.
No, Base64 is encoding, not encryption. It's a reversible transformation but not secure. Anyone can easily decode Base64 strings. For security, combine Base64 with actual encryption algorithms.
