Frequently asked questions
What is Base64 image encoding?
Base64 encoding converts binary image data into a text string. This allows images to be embedded directly in HTML, CSS or JSON without needing a separate image file.
When should I use Base64 for images?
Use Base64 for small icons or images you want to embed directly in HTML/CSS to reduce HTTP requests. Avoid it for large images as Base64 increases file size by about 33%.
What image formats are supported?
All common image formats are supported: PNG, JPG, GIF, WebP, SVG, BMP and more.
Is my image safe?
Yes. Your image is converted entirely in your browser — it never leaves your device and is never uploaded to any server.
How do I use Base64 image in HTML?
Use it as an img src: <img src="data:image/png;base64,YOUR_BASE64_HERE" />. Or in CSS: background-image: url("data:image/png;base64,YOUR_BASE64_HERE");
