What is a Image File to Base64 String Converter?
Base64 encodes binary files like images as plain text, so they can be embedded directly in HTML, CSS, JSON or email instead of being loaded as separate files. This saves a request for tiny icons, but makes files about 33% larger, so it is best for small images.

Frequently Asked Questions
Q:When should I use Base64 images?
For very small images such as icons under a few KB, in emails, or when a single file must contain everything. Larger images load faster as normal files.
Q:Why is the Base64 string bigger than the file?
Base64 uses 4 characters for every 3 bytes, so the text is about 33% larger than the original file.
