How It Works

What is JPG and What is PNG?
JPG (JPEG) is the most widely used image format for photographs and web images. It uses lossy compression to reduce file size, making it ideal for photos, product images, and any image with gradients. JPG is supported by every device, browser, and application. Learn more about JPG →
PNG is a lossless image format that supports full transparency (alpha channel). It preserves every pixel exactly without compression artifacts, making it perfect for logos, icons, screenshots, and graphics with text. PNG files are larger than JPG but maintain perfect quality. Learn more about PNG →
