About Image Formats
JPEG (JPG) is best for photographs with lossy compression, PNG uses lossless compression and supports transparency for graphics and screenshots, and WebP is a modern format by Google that often produces smaller files than both at equivalent quality.
Upload one or more images, select your desired output format (JPG, PNG, or WebP), adjust the quality slider for lossy formats, and click Convert. Download converted images individually or all at once. The tool processes everything using the browser's Canvas API with zero server uploads.
Image format conversion is commonly needed for optimizing website images for faster loading, preparing graphics for platforms with format restrictions, converting screenshots to JPG for smaller email attachments, and switching to WebP for modern web performance. Choosing the right format can reduce file sizes by 50-80% without visible quality loss.
JPG uses DCT-based lossy compression and is ideal for photos with smooth gradients. PNG uses DEFLATE lossless compression and excels at images with sharp edges, text, and transparency. WebP supports both lossy and lossless modes along with transparency and animation, making it the most versatile modern format for web use.
