Frequently Asked Questions
›When should I use Base64 images?
Base64 images are useful for: small icons and logos in CSS (saves HTTP requests), email templates (avoids blocked images), single-page apps with small assets, and APIs that need to transport images in JSON.
›Does Base64 increase image file size?
Yes, by about 33%. A 10KB image becomes roughly 13.3KB in Base64. For small images (under 5-10KB), the trade-off is often worth it to eliminate an HTTP request. For larger images, serve them as regular files.
›Is my image uploaded anywhere?
No. The encoding happens entirely in your browser using the FileReader API. Your image never leaves your device.
