PNG to WebP Converter - Free Desktop App

Yes. WebP fully supports alpha channel transparency — unlike JPG, which discards transparency entirely. Your transparent backgrounds, drop shadows, gradient opacity, and overlay effects are perfectly preserved when converting PNG to WebP. WebP actually handles transparency more efficiently than PNG, producing 50-70% smaller files for images with transparent areas.

Lossy WebP at 80-90% quality is typically 70-80% smaller than PNG with near-identical visual quality. Lossless WebP (pixel-perfect, no quality loss) is still 26% smaller than PNG on average. A 1MB PNG product image often becomes 200-300KB as lossy WebP, or 740KB as lossless WebP. The exact savings depend on image complexity — photos see larger reductions than simple graphics.

Convert all PNG images on your site to WebP for faster page loads and better SEO. In Diwadi, select your entire images folder and batch convert to WebP at 80-85% quality. Upload the WebP versions alongside your PNGs and use the HTML picture element to serve WebP to modern browsers with PNG fallback. This typically reduces total image payload by 60-70%, directly improving Core Web Vitals scores.

Yes. Shopify, WooCommerce, BigCommerce, and most modern ecommerce platforms support WebP. Converting product photos from PNG to WebP reduces page load times significantly, which improves conversion rates — studies show each second of load time costs 7% in conversions. Use Diwadi to batch convert your product catalog locally, keeping sensitive product images off third-party servers.

Lossless WebP preserves every pixel exactly like PNG — no quality loss at all — but is still 26% smaller than PNG. Lossy WebP discards subtle visual information for much greater compression — typically 70-80% smaller than PNG. For websites, lossy WebP at 80-90% quality is the standard choice. For archival purposes or images where pixel-perfect accuracy matters, use lossless WebP.

Yes. Diwadi handles unlimited batch conversions with no file count restriction. Select an entire folder and convert all PNG files to WebP in one operation. Processing happens locally on your computer, so conversion speed depends on your hardware rather than internet bandwidth. This is much faster than online tools that cap batch processing at 20-50 files.

Yes. Shopify natively supports WebP uploads and automatically serves them to compatible browsers. WordPress has supported WebP since version 5.8 (2021) and serves WebP through its media library. WooCommerce, Squarespace, Wix, and most modern CMS platforms also support WebP. You can safely convert your PNG images to WebP for any modern web platform.

Diwadi currently converts static PNG files to WebP. Animated PNG (APNG) files will be converted as a single static frame. WebP does support animation (as an alternative to GIF), but APNG-to-animated-WebP conversion requires specialized frame-by-frame processing. For animated images, consider converting APNG to GIF first, then to animated WebP using a dedicated animation tool.

For website images, use lossy WebP at 80-85% quality — this provides the best balance of file size and visual quality. For product photos or portfolio images, use 88-92% quality for higher fidelity. For thumbnails and social media, 75% is sufficient. If you need pixel-perfect quality (screenshots of text, technical diagrams), use lossless WebP. Diwadi shows estimated output size before conversion.

In 2026, over 97% of browsers support WebP, so fallback is rarely needed. If you must support very old browsers, use the HTML picture element to serve WebP with a PNG fallback. Keep your original PNG files and add WebP as an optimized alternative. Most CMS platforms (WordPress, Shopify) handle this automatically. For the vast majority of websites, serving WebP-only is safe.
