FAQ
What is Base64 encoding for images?
Base64 is a way to encode binary data (like images) into ASCII text. This allows you to embed images directly in HTML, CSS, or JavaScript without needing a separate image file.
Does Base64 increase file size?
Yes, Base64 encoding increases file size by approximately 33%. This is why it's best used for small images under 10KB. For larger images, regular files with caching are more efficient.
What's the difference between Data URI and raw Base64?
A Data URI includes the prefix 'data:image/png;base64,' which tells browsers how to interpret the data. Raw Base64 is just the encoded string without this prefix.
Is this tool secure?
Yes, all processing happens in your browser. Your images are never uploaded to any server. The conversion is done entirely client-side using JavaScript.
