Frequently Asked Questions
What is Base64 encoding?
Base64 is a binary-to-text encoding scheme that represents binary data in ASCII string format. It’s commonly used to embed images directly in HTML, CSS, or JavaScript code without requiring separate image files.
Why convert images to Base64?
Converting images to Base64 allows you to embed images directly in your code, reducing HTTP requests, avoiding broken image links, and making your applications more portable. It’s especially useful for small icons, logos, or when you need to include images in CSS or JavaScript.
What image formats are supported?
Our tool supports all major image formats including JPEG, PNG, GIF, WebP, BMP, and more. The tool automatically detects the format and generates the appropriate Base64 string with the correct MIME type.
Is there a file size limit?
While there’s no strict limit imposed by our tool, we recommend keeping images under 5MB for optimal performance. Very large images will result in very long Base64 strings that may cause browser performance issues.
Is my image data secure?
Yes, absolutely! All image processing happens locally in your browser. Your images are never uploaded to any server, ensuring complete privacy and security. The conversion process is entirely client-side using JavaScript.
How do I use the Base64 string in my code?
You can use the Data URL format directly in HTML img tags, CSS background-image properties, or JavaScript. For example: <img src=”data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAA…”> or in CSS: background-image: url(“data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAA…”);
What’s the difference between Data URL and Base64 Only formats?
Data URL format includes the complete data URI with MIME type (data:image/png;base64,ABC123…), ready to use directly in HTML or CSS. Base64 Only format provides just the encoded string (ABC123…) without the data URI prefix, useful when you need to construct your own data URI or use it in specific contexts.
