About PNG to WebP Converter

WebP is Google's modern image format that provides superior compression compared to both PNG and JPG. WebP lossless is 26% smaller than PNG on average; WebP lossy is 25-35% smaller than JPG at equivalent visual quality. All modern browsers support WebP.

Converting PNG images to WebP is one of the highest-impact actions for web performance optimisation. Google PageSpeed Insights specifically recommends serving images in "next-gen formats" like WebP as a performance improvement.

All conversion runs in your browser — your images never leave your device.

Frequently Asked Questions

Do all browsers support WebP?

Yes. WebP is supported in all modern browsers: Chrome, Firefox, Safari (since version 14), Edge, and Opera. As of 2024, global WebP support exceeds 96% of web users. For the remaining users, serving a PNG or JPG fallback via a <picture> element is best practice.

Does WebP support transparency?

Yes. WebP supports both lossless transparency (like PNG) and lossy transparency with an alpha channel. When converting a PNG with transparency to WebP, the transparency is preserved in the WebP output.

How much smaller will my WebP file be?

For lossless conversion (PNG to WebP lossless), expect 15-30% file size reduction. For lossy conversion at equivalent quality, expect 25-40% reduction compared to PNG. Results vary by image content — images with large uniform colour areas compress more than photographs.
