Frequently Asked Questions
When should I use Base64 images?
Use Base64 for small icons or images embedded directly in HTML/CSS to reduce HTTP requests. For large images, use regular file URLs — Base64 increases size by ~33%.
Is my image uploaded to a server?
No. Everything runs in your browser using the FileReader API. Your image is never sent anywhere.
How do I use it in CSS?
background-image: url('data:image/png;base64,...');
