About this conversion
Convert PNG to WebP to keep transparency and crisp graphics while shrinking file size. WebP supports both lossless and lossy compression with full alpha-channel support — so you get PNG's strengths at a fraction of the file size.
When this conversion is useful
- Shrinking transparent logos, icons, and UI graphics for the web
- Replacing PNG product shots with smaller WebP equivalents
- Optimising illustrations or diagrams without losing transparency
- Cutting bandwidth on image-heavy pages while preserving visual fidelity
Quality and tradeoffs
Use lossless WebP for graphics and screenshots — typically 20–30% smaller than the source PNG with no quality change. Lossy WebP is even smaller (50–70% reduction) but introduces tiny artefacts on flat colour and crisp text.
Frequently asked questions
Does WebP support transparency like PNG?
Yes. WebP has a full alpha channel and handles transparency identically to PNG. You won't lose any transparent regions in the conversion.
Should I use lossy or lossless WebP?
Lossless for logos, icons, screenshots, and anything with crisp edges or text. Lossy for photos and complex graphics where small artefacts won't be visible.
Why does Google recommend WebP?
WebP is significantly smaller than PNG and JPG at equivalent quality, which improves page-load speed — a measured Google ranking factor and a key Core Web Vitals input.
