Converting PNG to WebP: what to know
PNG is a lossless format that keeps transparency and stays sharp on logos, screenshots and graphics. WebP, on the other hand, is a modern format that is usually 25-35% smaller than JPG or PNG while supporting transparency. So converting a PNG to WebP makes sense whenever you want a modern and compact file while keeping a clean image.
WebP is now supported by every modern browser, so it is usually the best size-to-quality trade-off for the web.
Everything happens in your browser: your images never leave your device, with no upload and no watermark.
PNG vs WebP: what's the difference?
| Criterion | PNG | WebP |
|---|---|---|
| File size | Heavy | Often 50% lighter, sometimes more |
| Transparency | Yes | Yes — kept identical |
| Compression | Always lossless | Lossless or lossy, your choice |
| Compatibility | Universal | Modern browsers |
The gain is biggest on logos, screenshots and transparent visuals: WebP keeps PNG's transparency for a fraction of the weight.
