Frequently Asked Questions
What is Base64 encoding for images?
Base64 is a way to encode binary image data as text. This allows images to be embedded directly in code without needing separate files.
When should I use Base64 images?
Use Base64 for small images (under 10KB), icons, and graphics where reducing HTTP requests is beneficial. Avoid it for large images as it increases file size by ~33%.
What's the difference between Base64 and Data URI?
Base64 is just the encoded data. A Data URI includes the MIME type prefix (data:image/png;base64,) making it ready for use in HTML and CSS.
Does Base64 increase image size?
Yes, Base64 encoding increases the data size by approximately 33%. However, this overhead can be offset by eliminating HTTP request latency for small images.
Is my image data secure?
Yes, all conversion happens in your browser using JavaScript. Your images are never uploaded to any server.
