What is Base64 Encoding?
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It is commonly used to embed images directly into HTML, CSS, or JavaScript without needing separate image files.
A Base64 image string starts with data:image/png;base64, followed by the encoded data. This allows you to inline images in your code, reducing HTTP requests at the cost of slightly larger file sizes.
When to Use Base64
Use Base64 for small icons, email signatures, favicons, or CSS background images. For large images, stick with external files — Base64 adds about 33% to the file size.
Private & Secure
All encoding happens in your browser. Your images never leave your device — nothing is uploaded to any server.
