FAQ
Image to Base64: questions
When should I use Base64 images?
For tiny icons inside CSS or emails. For anything large, a normal image file is better because Base64 adds about 33% to the size.
Are my images uploaded anywhere?
No. Everything runs in your browser on your own device, so your files never leave it. You can even work offline once the page has loaded.
