What is Image to Data URI?

Image to Data URI converts image files into inline data strings starting with data:. Uses: 1) Embed small images in HTML/CSS to reduce HTTP requests; 2) Transfer image data in JSON; 3) Pass images in API calls; 4) Embed images in emails.

What image formats are supported?

All common formats: PNG, JPEG/JPG, GIF (including animated), SVG, WebP, BMP, ICO. The tool auto-detects the format and generates the correct Data URI prefix (e.g., data:image/png;base64,...).

Does Data URI encoding increase file size?

Yes. Base64 encoding converts binary to text, increasing size by ~33%. We recommend using Data URIs only for images under 10KB. For larger images, traditional file URLs are more efficient.

Is Image to Data URI safe?

Yes. Everything runs locally: Data URI Prefix and other values are processed on your device, never sent to a server — images are never uploaded to any server. The FileReader API reads images and encodes them in memory. Your data never leaves your device.

How do I use a Data URI?

HTML: <img src='data:image/png;base64,...'>; CSS: background-image:url('data:image/png;base64,...'). The tool includes the complete data: prefix — just copy and paste.

📖 About Image to Data URI

A Data URI embeds an image directly into HTML/CSS using the format data:[<MIME-type>][;base64],<data>. Compared to traditional image URLs, Data URIs reduce HTTP requests — ideal for small icons, logos, and inline graphics.

⚠️ Note: Base64 encoding increases size by ~33%. We recommend Data URIs for images under 10KB only. Use traditional URLs for larger images.
