Frequently Asked Questions
When should I use Base64 images?
Base64 images are best for small icons, logos, or UI elements under 10KB. They reduce HTTP requests but increase file size by ~33%. For larger images, regular file references are more efficient.
What image formats are supported?
This tool supports all common web image formats: PNG, JPEG, GIF, SVG, and WebP. The output includes the correct MIME type in the data URI.
Can I use Base64 images in CSS?
Yes, you can use Base64 data URIs in CSS background-image properties: background-image: url(data:image/png;base64,...). This is common for small decorative elements.
