Frequently Asked Questions

Frequently asked questions about the image to Base64 converter

What image formats are supported?

Our converter supports all common image formats including JPG/JPEG, PNG, GIF, WebP, BMP, and SVG. The tool automatically detects the format and processes it accordingly.

Is there a file size limit?

The recommended maximum file size is 10MB. Larger files may cause browser performance issues. For very large images, consider compressing them first or using server-side solutions.

What's the difference between Data URL and Base64?

Data URL includes the MIME type prefix (e.g., 'data:image/png;base64,') followed by the Base64 string. Base64 only contains the encoded image data without the prefix. Use Data URL for direct embedding in HTML/CSS.

Why is Base64 larger than the original file?

Base64 encoding increases file size by approximately 33% due to the encoding process. This is normal - Base64 represents binary data using only text characters, which requires more space.

Can I convert multiple images at once?

Currently, the tool processes one image at a time to ensure optimal performance and user experience. For batch processing, you would need to convert each image individually.

Is my image data secure?

Absolutely! All image processing happens locally in your browser. No files are uploaded to our servers, ensuring complete privacy and security of your images.

Can I use the Base64 output in any programming language?

Yes! Base64 is a universal encoding standard supported by virtually all programming languages. You can use the output in JavaScript, Python, PHP, Java, C#, and any other language.

How do I use the Data URL in HTML?

Simply paste the Data URL as the src attribute of an img tag: <img src='data:image/png;base64,iVBORw0KGgo...' />. You can also use it in CSS background-image properties.
