Ran a batch of jpegs through it and the AVIF output was noticeably smaller without obvious quality loss. Love that it all stays in the browser, no upload waiting around.
@anlahinkayetvg Hey Anıl, thanks for trying it out last month! I just shipped a major update — multi-worker parallel compression (up to 4x faster), a new demo showcase so you can see results before uploading, and better mobile support. Would love to hear what you think of the new version!
Compress images 85% smaller — 100% local, zero uploads, works offline

Hey Product Hunt! 👋
I'm ML, an indie maker from China. I built CompressFast because I was tired of sketchy online compressors that upload your images to who-knows-where.
3 things that make CompressFast different:
1️⃣ TRULY local processing
Open DevTools → Network tab. You'll see ZERO uploads. Everything happens in your browser via Web Workers + Canvas API. Disconnect your internet after loading the page — it still works.
2️⃣ Not just JPEG/PNG
8 formats in, 8 formats out. Including AVIF (next-gen, 50% smaller than JPEG) and HEIC (iPhone photos).
3️⃣ $0/month infrastructure
Built with Next.js + Web Workers + Upstash Redis + Creem. Hosted on Vercel free tier. Total monthly burn: $0.00. This means I can offer Pro as a $24.99 lifetime deal instead of yet another subscription.
📊 Numbers so far (1 month):
• 3,716 images compressed
• 178 users
• $24.99 revenue (1 Pro sale)
• $0.00 monthly cost
I built this in public on Twitter (@CompressFastApp) and wrote about the tech stack on Dev.to. Happy to answer any questions about the architecture, compression pipeline, or building a $0-infra SaaS!
