TuningImg - Privacy-first image toolkit. Process locally, never upload.

TuningImg is a privacy-first image workspace that works entirely in your browser. Compress, convert, resize, watermark and clean EXIF metadata — with zero server uploads. Supports PNG, JPEG, WebP and AVIF. Batch process multiple files, compare before/after, and download as ZIP. Built for designers, developers and anyone who values data privacy.

Hey Product Hunt! 👋 I built TuningImg because I was tired of uploading sensitive design assets and screenshots to random "free image compressor" sites. Every upload is a potential data leak — and most of us don't even think about it. TuningImg is different. Everything happens locally in your browser. There's no server processing, no cloud storage, no tracking your files. Just fast, professional-grade image tooling. Would love your feedback — especially on performance with large images and any formats you'd like to see supported. Fire away! 🔥
