What is it?
WebP es un formato de imagen moderno desarrollado por Google en 2010, diseñado específicamente para la web. Utiliza técnicas de compresión avanzadas derivadas del códec de video VP8 para lograr tamaños de archivo significativamente más pequeños que JPG y PNG sin pérdida de calidad visible.
WebP admite compresión tanto con pérdida como sin pérdida, así como transparencia (canal alfa) y animación, lo que lo convierte en un reemplazo versátil para JPG, PNG y GIF en contextos 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.
