Frequently asked questions
When should I use Base64 images?
For small images such as icons, where saving a separate request helps. Base64 is about a third larger than the file itself, and it cannot be cached separately, so large photos are better as normal files.
Is my image uploaded?
No. Everything happens inside your browser, so your files never leave your device and nothing is stored on a server.
