Frequently Asked Questions

A data URI embeds the image directly in HTML or CSS as a Base64 string, eliminating the need for a separate image file. Format: data:image/png;base64,iVBORw0KGgo...

Best for small images (under 10KB) like icons, logos, or simple graphics. Reduces HTTP requests but increases file size by ~33%. Good for email templates and single-file HTML.

PNG, JPG/JPEG, WebP, GIF, SVG, ICO, AVIF, and BMP. The output preserves the original format's MIME type for proper browser rendering.

Use the 'HTML img Tag' output format, which gives you: <img src="data:image/png;base64,..." alt="Image">. Copy and paste directly into your HTML.

Use the 'CSS Background' format, which outputs: background-image: url('data:image/png;base64,...'); Add this to your CSS rule.

Base64 encoding increases size by approximately 33%. A 10KB image becomes about 13.3KB of Base64 text. For large images, use regular files instead.

No. Base64 is lossless encoding - it preserves the exact binary data of your image. The decoded image is identical to the original.

Base64 encoding transforms binary images to text format - anyone can decode it. Encryption protects data with keys. Base64 provides no security, just format conversion for embedding in text files.

Currently this tool handles one image at a time. For batch conversion, you'd need to process each image separately.

Yes. All processing happens entirely in your browser using JavaScript. Images are never uploaded to any server - your files stay completely private.
