Optimize PNG images for modern web with WebP format. Superior compression, transparency support, batch processing, no registration needed.
Struggling with bloated PNG files that slow your site? WebP solves this by delivering the same transparency with dramatically smaller sizes. Google built this format specifically for web graphics, achieving compression rates that leave traditional PNG technology behind while preserving the alpha channel designers rely on.
Expect size reductions around 25-35% when switching from PNG. Those savings compound across your entire site - faster initial loads, smoother scrolling, happier visitors. Performance improvements show up in analytics and search rankings alike. Sites heavy on graphics benefit most, where dozens of PNGs can drag page speed into the red zone.
Web graphics need efficiency. PNG's approach works but wastes bandwidth by modern standards. WebP compresses the same visual data into much smaller packages, making it perfect for storefronts showcasing products, articles with illustrations, design portfolios, and anywhere transparency matters alongside speed.
PageSpeed Insights flags PNG files as optimization targets and specifically suggests WebP alternatives. This switch brings measurable wins - initial paint happens sooner, main content renders faster, layout stays stable. Search algorithms factor these metrics into rankings, with load speed being explicitly confirmed as important.
Today's browsers handle WebP universally - Chrome, Firefox, Safari, Edge, and Opera all render it natively. That's 95%+ coverage globally. Transparency works identically to PNG, so your logos and icons display perfectly. As a bonus, WebP compresses animations better than GIF while maintaining quality.
Hit "UPLOAD FILES" or drag graphics straight into the converter. Process up to 20 simultaneously - ideal for entire icon libraries, full product catalogs, or complete asset folders. Everything runs locally in your browser, so conversion starts instantly without upload delays.
Progress updates show in real-time as each file transforms. Our smart compression (90% quality preset) balances size against fidelity automatically. Grab individual results or bundle everything into a ZIP for deployment. Files up to 50 MB work fine, accommodating detailed artwork and high-resolution graphics.
Zero signup required, unlimited use, completely free. Ready for more? Click "NEW CONVERSION" to process another batch. WordPress sites accept these files directly in the media uploader, where modern themes handle them automatically.
Nothing leaves your machine. Conversion runs entirely in your browser through client-side processing - no uploads, no servers, no external storage. Your unpublished designs, proprietary graphics, and confidential visuals stay completely private.
Local execution means instant results without network delays. Original PNG files remain unchanged in their location. Converted WebP versions only exist where you save them. Complete control stays with you from start to finish, with zero exposure risk throughout.
