I’m documenting my progress while building a high‑performance offline image compression tool that supports 5 formats: JPG, PNG, WebP, TGA, and EXR.
The goal is simple:
- reduce file size without losing visual quality
- keep everything fully offline
- handle large images (including 8K)
- stay...

As web designers, we all deal with the same problem: large images slowing down page load times, hurting Core Web Vitals, and killing performance scores.
Over the past few months, I tested a bunch of image compression tools on real client projects, including JPG/PNG-heavy websites, WebP...
