What does Image ↔ Base64 actually do?

Image ↔ Base64 turns a local image file into a data URL or Base64 string, and can preview a data URL you paste. The file is read in the browser. Large images will produce very large strings and can slow the tab.

When should I use Image ↔ Base64?

Use it for a small icon or a fixture you must embed.

When should I not use Image ↔ Base64?

Do not embed multi-megabyte photos in source code.

What does Image ↔ Base64 not do?

A data URL is not an optimized asset pipeline. Does not resize, compress, or strip EXIF by default.
