FlexiWebP macOS image converter
FlexiWebP is a macOS app for fast, local image conversion to WebP and AVIF. The product helps reduce image weight and prepare assets for publishing on the web without uploading files to an external service.
The app was designed for people who regularly work with websites, stores, landing pages and web apps: developers, designers, agencies and website owners.
FlexiWebP solves a concrete problem in website delivery: heavy photos, galleries and product graphics slow down loading, hurt UX and affect SEO and Core Web Vitals.
Instead of using manual online tools, users can drag files into a native macOS app, choose WebP or AVIF, set quality and export ready-to-use files. The whole process runs locally on the Mac.
