Frequently Asked Questions
Base64 encoding is a technique that converts binary image data into an ASCII text string. This allows you to embed pictures directly into HTML, CSS, or JSON documents without hosting them as separate external files.
No. The entire conversion runs locally inside your web browser using HTML5 File and FileReader APIs. Your files are completely safe and never sent to or stored on any external server.
Yes. Base64 strings are typically around 33% larger in size compared to the original binary file. It is most effective for icons, logos, or smaller graphics to save additional HTTP requests.
This converter supports all common web image formats, including PNG, JPEG/JPG, WebP, SVG, GIF, ICO, and BMP.
You can paste the generated Data URI directly into the `src` attribute of an image element: <img src="data:image/png;base64,..." alt="Example">.
You can set it directly as a background image in your stylesheet using: background-image: url('data:image/png;base64,...');.
While there is no strict technical limit, files under 15MB are recommended so that your browser remains responsive during string processing and copying.
