What Are Image Formats?
PNG is a lossless format ideal for graphics, screenshots, and images with transparency. JPEG uses lossy compression that significantly reduces file size at the cost of some quality — best for photographs. WebP is a modern format developed by Google that provides both lossy and lossless compression, typically achieving 25-35% smaller files than JPEG at equivalent quality. Choosing the right format balances image quality, file size, and browser compatibility.
Common Use Cases
Convert PNG screenshots to JPEG for smaller email attachments. Transform images to WebP for faster website loading times. Convert transparent PNGs to JPEG with a white background. Batch test different quality levels to find the optimal size-quality tradeoff. Embed small images directly in HTML using Base64 encodingfor data URIs. All processing happens locally using your browser's Canvas API — your images are never uploaded to any server, making this tool safe for sensitive or proprietary images.
