What is the Image to Base64 Converter?
The Image to Base64 Converter encodes image files into Base64 strings that can be embedded directly in HTML, CSS, JavaScript, JSON, or other text formats. Upload any image (PNG, JPG, GIF, SVG, WebP) and instantly receive the Base64-encoded data URI ready to use in your code.
This tool processes images entirely in your browser for complete privacy. The Base64 output includes the data URI prefix making it ready to paste into src attributes, CSS backgrounds, or anywhere embedded images are needed.
Why Use the Image to Base64 Converter?
Base64 encoding eliminates the need for separate image files and HTTP requests. Embed images directly in code for faster page loads, simplified deployment, easier email templates, and reduced file management complexity.
Perfect for web developers embedding small icons and logos, email marketers creating HTML emails with inline images, API developers sending images in JSON payloads, and anyone needing to include images in text-based formats.
Common Use Cases
HTML Email Templates: Embed images directly in email HTML to ensure they display without requiring external hosting or dealing with blocked images.
Inline CSS Backgrounds: Include small images and icons in CSS files as data URIs to reduce HTTP requests and improve page load performance.
JSON Data Transfer: Encode images as Base64 strings for API requests, database storage, or configuration files that require text-only formats.
Simplified Deployment: Bundle images with code in single-file applications or tools that don't support external resource files.
How to Use the Image to Base64 Converter
Upload or drag-and-drop your image file into the tool. The converter instantly generates the Base64-encoded string with the appropriate data URI prefix (data:image/png;base64,...).
Copy the Base64 string and paste it directly into your HTML img src, CSS background-image, or anywhere you need an embedded image. The tool shows the original image size and encoded size for reference.
