FIELD NOTES / 013

Useful inline. Expensive when large.

Data URLs are handy for tiny assets and self-contained examples. Base64 increases the encoded size, so ordinary image files are usually better for larger assets.

Good to know

Does the image get uploaded?

No. FileReader and the browser image decoder handle it on this device.

Can I paste a screenshot?

Yes. Copy an image or take a screenshot, then paste anywhere on this page while Image → Base64 is selected.
