Frequently Asked Questions
Why convert images to Base64?
Base64 images can be embedded directly in HTML or CSS, reducing HTTP requests. Useful for small images, icons, or when you cannot host separate image files.
What is a data URI?
A data URI (data:image/png;base64,...) includes the MIME type and encoding, ready for use in src attributes or CSS url(). Raw Base64 is just the encoded data without the prefix.
Does Base64 increase file size?
Yes, Base64 encoding increases size by about 33%. Use it for small images (under 10KB). For larger images, traditional hosting with proper caching is more efficient.
What is Base64 image encoding?
Base64 encoding converts binary image data into ASCII text. This allows images to be embedded directly in HTML, CSS, or JavaScript without separate file requests.
When should I use Base64 images?
Use Base64 for small images like icons, logos, or UI elements to reduce HTTP requests. Avoid it for large images as Base64 increases file size by about 33%.
What image formats are supported?
This tool supports PNG, JPG, JPEG, GIF, SVG, WebP, and other common image formats. The output includes the correct MIME type in the data URL.
Is my image data secure?
Yes, all image processing happens locally in your browser. Your images are never uploaded to any server.
