What is Base64 encoding for images?

Base64 encoding converts binary image data into an ASCII text string. This allows you to embed images directly into HTML, CSS, or JSON files using Data URIs, eliminating the need for separate image file hosting.

When should I use Base64 images instead of image files?

Base64 images are useful for small icons, email templates, single-file HTML documents, and API payloads where embedding the image inline is more convenient than hosting a separate file. For large images, traditional file references are generally better for performance.

Does Base64 encoding increase file size?

Yes, Base64 encoding increases file size by approximately 33%. A 100 KB image will become roughly 133 KB in Base64. This is a trade-off for the convenience of inline embedding.

What image formats are supported?

The encoder supports PNG, JPG, WebP, GIF, BMP, SVG, and most other browser-supported image formats. The decoder can handle any valid Base64 string representing an image.

Is my image data sent to a server?

No. All encoding and decoding is performed entirely in your browser. Your images and Base64 strings never leave your device, ensuring complete privacy.

Can I use the Base64 output directly in CSS?

Yes. The tool generates a complete Data URI (e.g., data:image/png;base64,...) that you can use directly in CSS background-image properties or HTML img src attributes.
