❓ Frequently Asked Questions
Everything you need to know about Base64 image encoding
What is Base64 encoding?
Base64 is a binary-to-text encoding scheme that represents binary data in ASCII format. It's commonly used to embed images directly in HTML, CSS, or JSON without requiring separate image files.
When should I use Base64 images?
Base64 images are ideal for small icons, logos, or graphics that you want to embed directly in your code. They reduce HTTP requests but increase file size by about 33%, so they're best for small images under 10KB.
What's the difference between Data URI and Base64?
Base64 is the encoding method, while Data URI is the complete format including the MIME type. A Data URI looks like: data:image/png;base64,iVBORw0KGgo...
Are there any size limitations?
While there's no technical limit to Base64 encoding, some browsers and email clients have practical limits. Most modern browsers support Data URIs up to 2MB, but for best performance, keep images under 100KB.
Is my image data secure?
Yes! All image processing happens directly in your browser using JavaScript. Your images are never uploaded to our servers or stored anywhere. The conversion is completely client-side and private.
