Image to Base64 Encoding

Converting images to base64 lets you embed images directly in HTML, CSS, JSON, and emails without separate file requests. The output can be used as a data URL like data:image/png;base64,....

Benefits of Base64 Images

Base64 images can reduce HTTP requests and simplify asset distribution for small logos, icons, favicons, and UI graphics.

When to Use Base64 Images

Use base64 for small images, usually under 32KB. Larger photos are usually better served as normal image files because base64 increases size and reduces caching efficiency.

Supported Image Formats

This encoder supports the image formats your browser can read, including PNG, JPEG, GIF, WebP, SVG, and BMP.

Performance Considerations

Inline base64 assets are convenient, but they are not always faster. Balance fewer requests against larger HTML, CSS, or JSON payloads.
