Frequently Asked Questions
What is a Base64 data URL?
A data URL embeds the image data directly as a Base64 string, like data:image/png;base64,iVBORw0... You can use it in <img src> or CSS url() without a separate file request.
Why use Base64 for images?
It eliminates an extra HTTP request, which is useful for small icons, favicons, or images in HTML emails. For large images, a separate file is usually better for performance.
Does this work for all image types?
Yes — JPG, PNG, WebP, GIF, BMP, and SVG all work. The output preserves the original MIME type.
Is my image uploaded anywhere?
No. Conversion happens entirely in your browser via the FileReader API. Your image never leaves your device.
