Frequently Asked Questions

What is the difference between this and the full Image to Base64 tool?

This tool focuses on speed with no configuration options. The full tool offers batch conversion, format selection, and output customization.

What file types are supported?

PNG, JPG, WebP, SVG, GIF, ICO, and BMP. The tool auto-detects the format from the file header.

Is there a size limit?
