What is Base64 encoding?

Base64 encoding converts binary image data into a text string using 64 ASCII characters. This allows images to be embedded directly in HTML, CSS, or JSON without a separate file.

Does Base64 increase file size?

Yes, Base64 encoding increases the data size by approximately 33%. It's best for small images (icons, logos) rather than large photos.

What image formats can I convert?

This tool supports PNG, JPG, WebP, and GIF formats. The output is always a data URI with the correct MIME type.

When should I use Base64 images?

Base64 is ideal for small images in emails (which can't load external images), single-page applications, or reducing HTTP requests for small icons.
