PNG is great for graphics but terrible for file size - a typical PNG is 5-10x larger than its WebP equivalent at visually-identical quality. Convert one PNG or batch hundreds, with transparency preserved and quality/lossless toggles, in your browser. Boosts Core Web Vitals when used for web assets.
When to use this
Where PNG to WebP pays off most: blog post images, e-commerce product photos saved as PNG, UI screenshots in docs, logo files for websites, app store screenshots that are PNG by default. Often the single biggest LCP win you can ship.
Frequently Asked Questions
Will transparency be preserved?
Yes - WebP supports the same alpha channel as PNG. Transparent pixels stay transparent after conversion. Solid-color PNGs and graphics with transparency both convert cleanly.
How much smaller will the WebP be?
Typically 60-90% smaller than the source PNG. Photo-like PNGs (screenshots, scanned documents) see the biggest savings; pure flat-color graphics see less because PNG was already efficient for them.
