Mirror Image Tool – Flip images in browser with complete privacy

I built a simple image flipping tool that runs entirely in your browser. No uploads, no servers – all processing happens client-side using Canvas API.

The main motivation was privacy. I got tired of uploading personal photos to random sites just to flip them, not knowing where they end up. So I made this as a zero-trust alternative.

It supports horizontal/vertical flips, batch processing with ZIP downloads, and handles PNG/JPEG/WebP/GIF. Also added keyboard shortcuts (H/V/B) because why not.

The tool is free and open for anyone to use. No tracking, no registration.

Would appreciate any feedback on the UX or suggestions for other privacy-focused image tools people might need!
