Which image format is best for compression: JPG or PNG?

For photographs and images with gradients, JPG compression is best because it can achieve much smaller file sizes (often 50-80% reduction) with minimal quality loss. For graphics, logos, screenshots, and images with text, PNG is better because it preserves sharp edges and supports transparency, though file size reduction is typically only 10-30%. A newer format like WebP offers the best of both worlds with 25-34% smaller files than JPG and 26% smaller than PNG. Our image size reducer supports all formats and helps you choose the optimal format for your specific image type.
