Frequently Asked Questions

Quick answers to common questions about Base64 encoding.

What is Base64 encoding for images?
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.
Are my images uploaded to any server?
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.
Does Base64 encoding increase file size?
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.
Which image formats are supported?
This converter supports all common web image formats, including PNG, JPEG/JPG, WebP, SVG, GIF, ICO, and BMP.
How do I use Base64 in HTML?
You can paste the generated Data URI directly into the `src` attribute of an image element: <img src="data:image/png;base64,..." alt="Example">.
How do I use Base64 inside CSS?
You can set it directly as a background image in your stylesheet using: background-image: url('data:image/png;base64,...');.
Is there a file size limit?
While there is no strict technical limit, files under 15MB are recommended so that your browser remains responsive during string processing and copying.
