Show HN: ResizeImage.dev – A fast image resizer runs in browser (resizeimage.dev)
3 points by wainguo 232 days ago
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

https://resizeimage.dev

Feedback welcome

I’d love feedback from the HN community

Thanks for reading!

do not use ai，it just crop image， or adjust image dimensions and file size if bulk，it use in browser ability to complete the tasks
