What is Base64 encoding?

Base64 is a way to encode binary data (like images) as ASCII text. This lets you embed images directly in HTML, CSS or JavaScript without separate files.

Will this increase file size?

Yes, Base64 encoding increases size by about 33%. It's best for small images like icons, logos and thumbnails.

When should I use Base64 images?

Use Base64 for small images to reduce HTTP requests, for email templates, for embedding in JSON/APIs, or when you can't host separate files.
