Image to HTML converter — convert image to HTML code

Free online image to HTML converter. Convert JPG, PNG, WebP, BMP, SVG images to HTML code with base64 embedding. No upload, instant conversion, copy or.

What is an Image to HTML Converter?

An image to HTML converter is an online tool that transforms your image files (JPG, PNG, WebP, BMP, SVG) into HTML code by encoding the image as a base64 data URI. The resulting HTML contains a self-contained img tag that displays your image without requiring a separate image file. All processing happens locally in your browser using the HTML5 Canvas API — your images are never uploaded to any server. The generated HTML code can be copied to your clipboard or downloaded as an .html file that opens directly in any web browser.

Tips for Image to HTML Conversion

Best practices for getting the most out of your HTML image conversion.
  • 01

    Optimize Images Before Converting

    Smaller source images produce smaller base64 strings. Consider compressing or resizing large images before conversion for more manageable HTML code.

  • 02

    Use for Small to Medium Images

    Base64 encoding increases file size by about 33%. This tool is ideal for icons, logos, and moderate-sized photos. For very large images, consider external hosting.

  • 03

    Add Custom Alt Text After Copying

    The generated HTML includes a generic alt attribute. After pasting, customize the alt text for accessibility and SEO.

  • 04

    Choose the Right Format

    Use PNG for images with transparency, JPEG for photos, and WebP for the best compression. The output preserves your original image format.

  • 05

    Test Before Deploying

    After downloading the HTML file, open it in a browser to verify the image displays correctly before using it in production.

  • 06

    Combine with CSS for Styling

    The generated HTML is basic by design. Add your own CSS classes, responsive styles, or inline styles to customize the image display.

Technical Details

How the image to HTML conversion works under the hood.
Canvas-Based Encoding
Uses the HTML5 Canvas API to draw the image and export it as a base64 data URI using canvas.toDataURL().
Client-Side Only
All processing runs exclusively in the browser using JavaScript. No data is sent to or stored on any server.
Supported Input Formats
JPG, JPEG, PNG, WebP, BMP, SVG. Images up to 15 MB. Larger images are automatically downsampled to a maximum edge of 2048 pixels.
Output: HTML with Base64
Generates valid HTML5 markup with a base64-encoded image inside an img tag. Includes src, alt, width, and height attributes.
Download Format
Downloads as a .html file with a standard HTML5 document structure. Opens correctly in Chrome, Firefox, Safari, Edge, and all modern browsers.
Format Preservation
The output MIME type matches your input format (image/png for PNG, image/jpeg for JPEG, image/webp for WebP), preserving image quality characteristics.
