Frequently asked questions

When should I use Base64 images?

For tiny icons and placeholders (a few KB) where saving a request helps. Base64 makes files about 33% bigger and can't be cached separately, so keep large images as normal files.

Is my image uploaded?

No. It is read and encoded in your browser.
