Frequently asked questions

What is a Base64 data URI?

A data URI embeds the image content directly in text form (e.g., data:image/png;base64,iVBOR...). The browser renders it without making a separate HTTP request.

When should I use Base64 images?

For small images (under ~10 KB) where eliminating an extra HTTP request provides a net benefit. For large images, separate files are more efficient.

What formats are supported?

JPEG, PNG, GIF, WebP, SVG, and any format your browser supports can be encoded.

Is my image data private?

Yes. The entire encoding process runs in your browser using the FileReader API. No data is sent to any server.
