About PNG to WebP

Convert PNG images to WebP format for smaller file sizes. WebP typically produces 25-35% smaller files than PNG at similar visual quality. Ideal for web images where loading speed matters. We tested by converting a 4.2MB PNG photo to WebP at 90% quality, producing a 1.1MB file — a 74% reduction. A 2.4MB PNG screenshot converted to 680KB WebP — a 72% reduction with no visible quality loss.

Supported formats: Input: PNG, Output: WebP

Limits: Maximum 10 images per batch; Animated PNGs (APNG) are not supported; WebP output uses lossy compression — not suitable for images that require lossless quality; Very old browsers may not display WebP images

How It Compares

Unlike Squoosh (by Google) which handles one image at a time with no batch support, this tool converts up to 10 PNGs in a single batch. CloudConvert handles batch conversion but requires uploading files to their servers with a 10-per-day free limit. This tool runs entirely in your browser with no upload.

Privacy & Security

Because processing happens directly in your browser, your files and input are not uploaded to our servers.
