Frequently Asked Questions

Find answers to common questions about this tool.

What image formats can I convert to Base64?

PNG, JPG, GIF, WebP, SVG, and BMP. Each format generates a data URI with the correct MIME type prefix.

What is the maximum file size for conversion?

The limit is 10 MB. Base64 encoding increases file size by approximately 33%, so large files may be slow to process.

Yes. Click "Copy" to copy the full data URI to your clipboard. The string can be pasted directly into an <img> src attribute.

Does the tool generate CSS background-image syntax too?

Yes. Toggle "CSS Format" to output the Base64 as a CSS background-image: url(...) property ready to paste into a stylesheet.

Can I convert a remote image URL to Base64?

Yes. Enter an image URL instead of uploading a file. The tool fetches the image and converts it.
