Image to Base64 - Convert an Image to a Data URI

Convert an image file into a Base64-encoded Data URI (e.g. data:image/png;base64,...). This is useful for embedding small images in HTML/CSS, emails, or JSON payloads.

Why Convert an Image to Base64?

  • Embed Anywhere: Inline images in HTML, CSS, or JSON without separate files
  • Portable: Move a single string across systems without file handling
  • Great for Demos: Quickly include images in prototypes
  • Client-side: Conversion happens in your browser

Common Use Cases

📧 Email Templates

Embed small icons without additional attachments.

🧪 Prototypes

Keep everything self-contained in a single HTML file.

🎨 CSS Backgrounds

Inline background images for quick experiments.

🔌 APIs

Send images as strings when a file upload isn’t available.

How to Use This Tool

  1. Upload an image: Choose a local image file.
  2. Get the Data URI: The Base64 string appears in the output box.
  3. Copy & use: Paste it into HTML/CSS/JSON where needed.

Field guide: The output includes the correct MIME type prefix (like image/png).

This conversion runs entirely in your browser.

Important Notes

  • Base64 strings are larger than the original file (typically ~33% bigger).
  • For large images, prefer serving the file normally instead of inlining.
