Show HN: ResizeImage.dev – A fast image resizer runs in browser
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.
Try it
