When should you convert an image to Base64?
Base64 is best for small, self-contained assets where convenience matters more than raw file efficiency. It is common in code examples, CSS snippets, HTML prototypes, API fixtures, and documentation. For production website photos, a normal image file is usually faster because browsers can cache it separately, stream it efficiently, and avoid the extra text size that Base64 introduces.
If you embed Base64 in CSS or HTML, keep the asset small, check page weight, and avoid repeating the same encoded string across many pages. For larger images, use optimized WebP, AVIF, JPG, or PNG files instead.
