Why PNG Files Are Often Larger
PNG uses lossless compression, which preserves every pixel exactly. This is ideal for screenshots, logos, UI exports, and images with transparency — but it results in larger file sizes than formats like JPG or WebP, especially for images with many colors or fine detail.
Converting PNG to WebP usually produces a significantly smaller file while keeping good visual quality and preserving transparency. The output is ready to use in modern browsers, where WebP support is universal.
PNG with transparency
WebP fully supports transparency. After compression, check the preview to confirm transparent areas look correct before downloading. If edges look rough, try Best Quality mode or avoid enabling the resize option.
