Frequently Asked Questions

Is the Base64 real?

Yes, it is generated from the selected file bytes.

Is there an upload?

No.

Should I Base64 huge images?

Usually no; Base64 increases data size.

Using Base64 images wisely

Base64 turns an image into text you can paste straight into HTML or CSS, which saves one network request. That is a good trade for tiny icons and logos, and a poor one for photos: Base64 makes the data about a third bigger and the browser cannot cache it separately.

Use the Data URI in an img tag's src or in CSS background-image. Keep embedded images under a few kilobytes, and compress the image first so the string stays short.
