Frequently asked questions

Is my image uploaded to encode it?

No. The Base64 encoding is done in your browser with the FileReader API, so your image never leaves your device.

When should I use a Base64 image?

Inline Base64 images avoid an extra HTTP request, which suits small icons. For larger images a normal file is usually smaller and faster, since Base64 adds about 33% overhead.
