•<strong class="text-foreground font-semibold">25–50% smaller file sizes</strong> at equivalent quality •<strong class="text-foreground font-semibold">Transparency support</strong> — WebP handles alpha channels just like PNG •<strong class="text-foreground font-semibold">Better Core Web Vitals</strong> — Smaller images improve LCP (Largest Contentful Paint), a key Google ranking signal •<strong class="text-foreground font-semibold">Universal browser support</strong> — Chrome, Firefox, Safari, Edge, and all mobile browsers support WebP

For websites, the conversion from PNG to WebP is one of the highest-ROI performance improvements you can make.

| Metric | PNG | WebP | Savings | |--------|-----|------|---------| | Logo (512×512) | 45 KB | 18 KB | 60% | | Hero Image (1920×1080) | 2.1 MB | 980 KB | 53% | | Product Photo (800×800) | 320 KB | 145 KB | 55% | | Screenshot (1440×900) | 890 KB | 410 KB | 54% |

All conversion happens locally — no files are sent to any server. Perfect for logos, screenshots, and product images that may contain proprietary designs.

Logos and icons — Convert to WebP. The transparency support is identical to PNG, and file sizes drop dramatically. Consider also using SVG for logos that need to scale infinitely.

Screenshots and UI mockups — WebP excels here. Clean edges and text in screenshots compress beautifully in WebP format.

Product photography — Use WebP at 80–85% quality. Product detail remains sharp while file sizes drop by half.

Animated PNGs (APNG) — WebP supports animations too. Convert APNG to WebP for smaller animated files on the web.

After converting, use the HTML <picture> element to serve WebP with PNG fallback:

`html `

Next.js users: Use the built-in <Image> component, which automatically serves WebP to compatible browsers.

For WordPress: Install a WebP plugin or use a CDN like Cloudflare that auto-converts on the fly.

PNG → WebP — Best for web. 25–50% savings, transparency preserved

PNG → JPEG — Smaller files but loses transparency. Use only for photos without transparent backgrounds

PNG → AVIF — Even smaller than WebP (30–50% more savings) but slightly less browser support. Good for cutting-edge sites

PNG → SVG — Only works for vector graphics, not photographic content. Best for logos converted from vector sources

For most web use cases, PNG → WebP is the ideal conversion with the best balance of compatibility and compression.
