Frequently Asked Questions
Why convert images to Base64?
Base64-encoded images can be embedded directly in HTML, CSS, or JavaScript, eliminating HTTP requests. This is useful for small icons, logos, and email templates.
Does Base64 increase file size?
Yes. Base64 encoding increases the data size by approximately 33%. This is why it is recommended only for small images (under 10KB). Larger images should be served as regular files.
What image formats are supported?
This tool supports all common image formats: PNG, JPEG, GIF, SVG, WebP, ICO, and BMP. The output includes the correct MIME type in the data URI.
Is my image uploaded anywhere?
No. The conversion happens entirely in your browser using the FileReader API. Your images are never sent to any server.
