The file is read with FileReader in your browser only.

When should I inline an image as Base64?

It's useful for tiny icons or single-file demos to save a request. For larger images, a normal file is usually more efficient.

Why is the Base64 bigger than the file?

Base64 adds roughly 33% overhead because it represents binary data using text characters.

Does it change the image?

No. It encodes the exact bytes of your file into text; decoding gives back the identical image.
