I built a privacy-first image toolkit — all processing happens in your browser, zero server uploads

Every image tool I've used online uploads files to their servers for processing. I wanted something that doesn't.

NullUpload processes images entirely in your browser using Canvas API and WebAssembly. Nothing is uploaded, nothing is tracked, no accounts needed.

Tools included: image compression, format conversion (JPG/PNG/WebP/AVIF), resizing, and EXIF metadata stripping (shows GPS warnings).

Source code is public so you can verify: https://github.com/Lordkro/nullupload

Looking for feedback on the tools and UX.
