Image to Base64 Converter — Frequently Asked Questions

What is a Base64 data URI?

A data URI embeds the image data directly in a URL string (data:image/png;base64,...). This allows images to be inlined in HTML, CSS, or JSON without a separate HTTP request.

Is there a file size limit?

There is no hard limit, but very large images will produce very long Base64 strings. For web performance, consider using data URIs only for small images like icons and sprites.
