Question 1

What is Image to Data URI?

Accepted Answer

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.

Question 2

What image formats are supported?

Accepted Answer

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,...).

Question 3

Does Data URI encoding increase file size?

Accepted Answer

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.

Question 4

Is Image to Data URI safe?

Accepted Answer

Yes. All processing happens locally in your browser — images are never uploaded to any server. The FileReader API reads images and encodes them in memory. Your data never leaves your device.

Question 5

How do I use a Data URI?

Accepted Answer

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.
