Hey Product Hunt! 👋 I built LocalResizer because I was frustrated with image tools that upload your files to servers — you never really know what happens to them after. So I built something different: everything runs in your browser. Your images never leave your device. Zero uploads, zero tracking, zero accounts needed. What it does: Compress JPEG, PNG, WebP to any target file size Resize images by pixel dimensions or file size Batch process up to 20 files at once Works offline after first load The secret sauce is a pSEO architecture — one processing engine powers dozens of platform-specific pages (YouTube thumbnails, Instagram sizes, Discord limits, etc.). It's completely free and open source (MIT). Would love your feedback — especially on the PNG compression flow, which was the trickiest part to get right! 🙏
