Frequently Asked Questions

What's the difference between Data URL and pure Base64?

A Data URL includes the "data:image/[type];base64," prefix followed by the Base64 data. Pure Base64 is just the encoded data without the prefix. Data URLs can be used directly in img src attributes, while pure Base64 may need the prefix added depending on usage.

When should I use Base64 images?

Base64 is best for small images (under 10KB) that are used repeatedly in your website. For larger images, traditional file hosting is more efficient as Base64 increases file size by about 33% and can't be cached separately.

Will the quality of my image be affected?

The Base64 encoding process itself doesn't affect quality, but if you resize or compress the image before encoding, quality may be impacted. You can control this with the quality slider and resize options.

Is this tool secure? Where are my files stored?

Your files never leave your computer. All processing happens in your browser, making it much more secure than uploading to a server. Once you close the page, all file data is cleared.

How do I use the Base64 string in my code?

For Data URLs, you can use them directly in HTML (img src="data:image/...") or CSS (background-image: url('data:image/...')). For pure Base64, you'll need to add the appropriate prefix before using it.

Can I convert multiple images at once?

Yes, you can upload multiple images and they'll be converted together. Each image's Base64 data will be clearly labeled in the output.
