Show HN: ResizeImage.dev – A fast image resizer runs in browser
resizeimage.devHey 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
Feedback welcome
I’d love feedback from the HN community
Thanks for reading!

Resize could be ether dimensions or file size, resize is a bit （Homographic pun） so does it use ai to scale up or something? 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
