What is Base64 encoding?
Base64 is a binary-to-text encoding that represents binary data as ASCII characters. It's commonly used to embed images directly in HTML, CSS, or JSON without needing a separate file. A data URI combines the MIME type with the Base64 string, like: data:image/png;base64,iVBOR...
Will this increase file size?
Yes, Base64 encoding increases size by roughly 33%. It's best used for small images (icons, logos, small graphics) where eliminating an extra HTTP request is more valuable than the size increase.
