Hey everyone – creator here! 👋 Most image compressors either destroy quality (hello, Photo Compress 2.0) or can't handle large files (anything above 20 MB and they crash). They also require internet, upload your photos to unknown servers, and give you zero control over quality vs. file size. **ETK Image Compressor** solves all of that: ✅ **Up to 90% size reduction** while keeping almost lossless quality – proven by side‑by‑side video comparisons against the top 5 Google Play compressors. ✅ **Works offline** – no images ever leave your device. Privacy first. ✅ **Supports huge files up to 50 MB** – competitors die at 20 MB. ✅ **Live preview** – you see the difference before saving. ✅ **Dead simple** – 3 steps, no bloat, no intrusive ads. **Why is it better?** I built a proprietary adaptive algorithm that focuses on the **quality‑to‑size ratio**, not just shrinking numbers. The results speak for themselves: a 10 MB image becomes 1.4 MB with 99.6% SSIM similarity (see the video in the gallery). **Free version** is already live on Itch.io (Windows + macOS). **Pro version** (batch processing, manual quality/resolution, advanced formats like WebP/AVIF, no watermark, 2x speed) will launch very soon at $29.99 one‑time. I’m a solo developer from Iran, and this is the result of years of research. I’d love your feedback, upvotes, and any feature requests. Let me know what you think! 🙌

ETK Image Compressor – World’s strongest image compression (free, offline)

Hey everyone I m the developer behind **ETK Image Compressor**.

After months of research, I built what I believe is the strongest image compression algorithm in the world. It reduces file size by up to 90% while preserving almost lossless quality proven by side by side video comparisons against Photo Compress 2.0, Reduce Photo Size, and JPEGmini.
