About Base64

Base64 is an encoding scheme that converts binary data into ASCII text format. It's commonly used to encode images, files, or text for transmission over text-based protocols like email or JSON APIs. While not encryption, Base64 makes binary data safe for text-only channels. Our tools let you encode text to Base64, decode Base64 to readable text, or convert between Base64 and other formats — all processed locally in your browser for complete privacy.

Common Use Cases:

•Encode images for embedding in HTML/CSS
•Encode credentials for HTTP Basic Auth
•Decode Base64-encoded API responses
•Convert binary data for JSON transmission
•Encode/decode email attachments

🔒 Privacy First: All conversions happen locally in your browser. Your data never leaves your device.
