Frequently Asked Questions
What image formats are supported?
All browser-supported formats: PNG, JPEG, GIF, SVG, WebP, BMP, ICO, and more.
Why convert images to Base64?
Base64 images can be embedded directly in HTML/CSS without extra HTTP requests, useful for small icons and email templates.
Is there a file size limit?
No hard limit, but Base64 increases file size by ~33%. Large images (>1MB) may produce very long strings.
