Show HN: Smallimg.cc – A client-side image compressor with no uploads

Hi HN,

I built a free image compression tool called Smallimg.cc that runs entirely in the browser.

The main motivation was privacy. I was never comfortable uploading potentially sensitive images to a third-party server just for compression. This tool solves that by using JavaScript and WebAssembly to perform all the processing on the client-side. Your files are never transferred over the network.

Key features:

Total Privacy: Your images never leave your computer.

Incredible Speed: No upload/download time, just instant processing.

Full Control: You can adjust quality, resize, and convert formats (JPG, PNG, GIF, WebP) on the fly.

Accessible to All: It's completely free, requires no sign-up, and now supports 10 languages!

I focused on creating a clean UI and making it as fast as possible. I'm looking for feedback on performance, features you think are missing, and any potential bugs.

Thanks for checking it out: https://smallimg.cc/
