How It Works

Transform your JPG images into Base64 encoded strings using our advanced browser-based converter. The process begins by loading your JPG file into a canvas element, preserving the photographic quality and color accuracy that JPG format provides. Our converter then extracts the pixel data and encodes it into a Base64 string with proper data URI formatting (data:image/jpeg;base64,...). This creates a text representation of your JPG image that can be directly embedded in HTML, CSS, JavaScript, or database storage. JPG format is ideal for photographs and complex images with many colors. All processing happens locally in your browser using modern Canvas APIs - no uploads, no server processing, complete privacy guaranteed. Perfect for web development, email templates, and reducing HTTP requests for photographic content.
