Hey HN I built ResizeImage.dev that runs 100% client-side — nothing gets uploaded, and it’s instant. What it does Resize, crop, and optimize images directly in your browser Supports JPG, PNG, WebP Works offline (PWA-ready) No tracking, no server, no data collection How it works It uses the Canvas API and WebAssembly codecs to process everything locally. All transformations happen in-memory, so no files ever leave your machine. Why I built it I needed a simple, no-BS way to resize images for web and social media — something fast, private.
