このシナリオでよくある問題
Large files create long strings
Use Base64 for small assets; large images can bloat HTML or CSS.
Data URL vs raw Base64
Data URL includes the MIME prefix; raw Base64 only contains the encoded data.
Preview before sharing
Check the preview to make sure the encoded image still matches the source.

Use Data URL for browser rendering and raw Base64 when a system requests only encoded data.

They can, but the resulting text becomes very long and may hurt performance.
