What is it?
WebP adalah format gambar modern yang dikembangkan oleh Google pada tahun 2010, dirancang khusus untuk web. Ini menggunakan teknik kompresi canggih yang berasal dari codec video VP8 untuk mencapai ukuran file yang jauh lebih kecil dibandingkan JPG dan PNG tanpa kehilangan kualitas yang terlihat.
WebP mendukung kompresi dengan kehilangan dan tanpa kehilangan, serta transparansi (saluran alfa) dan animasi - menjadikannya pengganti yang serbaguna untuk JPG, PNG, dan GIF dalam konteks web.

Is WebP better than JPG?
For web use, yes. WebP produces 25-35% smaller files at the same visual quality. However, JPG has broader software support and is still preferred for photography workflows.
Does Safari support WebP?
Yes. Safari added full WebP support in version 14 (2020). All modern browsers now support WebP.
Can WebP replace both JPG and PNG?
Yes, WebP can handle both use cases - lossy compression for photos (replacing JPG) and lossless with transparency (replacing PNG) - while producing smaller files in both cases.
How do I open a WebP file?
Most modern browsers open WebP directly. For desktop use, update your OS image viewer or use image editing software like Photoshop (with a plugin) or GIMP.
Should I convert my website images to WebP?
Yes, if web performance is a priority. Serving WebP to supporting browsers and JPG/PNG as a fallback for older browsers is considered best practice.
