Most tools I tried for PNG-to-SVG produced "off" conversions where the PNG didn't match the original SVG, usually due to scaling issues or poor rendering. Squoosh, however, provides a pixel-perfect result every single time. It has now become my go-to for all image optimization and conversion needs.

Awful, laggy, crashed on me 3 times and froze completely had to force stop.

One of the best experience for compressing images to jpegs or even pngs. Fast, intuitive UI, reliable, multiple compression algorithmes to choose and rapidly see how it impact the final image.
Too bad, no local desktop Windows version???
Packed with features and formats (including webp and avif). Runs in the browser and can be installed as a PWA. Compression performance is excellent.
