Why this beats online converters
Most online image optimizers upload your files to their servers, which adds latency and privacy risk. This workflow processes everything locally in your browser using the Canvas API — your images never leave your device. You get the same WebP compression quality as Squoosh or TinyPNG, but with batch ZIP export and zero upload.
Best for LCP scores
Google's Largest Contentful Paint metric penalizes images that are too large. Converting hero images to WebP at 80% quality and capping width at 1920px typically cuts image payload by 60-75%, directly improving your Core Web Vitals.
