When should I use Base64 vs a regular image file?

Use Base64 for small icons under ~5KB to save an HTTP request. For larger images, use regular files — Base64 increases size by ~33% and bypasses browser caching.

Is my image uploaded to your server?

No. The FileReader API converts the image entirely in your browser. It never leaves your device.
