Hey Product Hunt! 👋 I'm Haider, maker of PixKilo.

Whenever I needed to resize an ID photo or compress an image below 50 KB for an official government or job portal, existing online tools were frustrating:
1. They required uploading sensitive personal photos to third-party cloud servers.
2. They enforced artificial daily quotas, account registrations, or watermarks.
3. They used vague percentage sliders (e.g., 60% quality) requiring endless trial-and-error to meet strict document limits.

I built PixKilo to fix this: a suite of fast, lightweight image tools that run entirely client-side in your browser using React 19, Vite, and the HTML5 Canvas 2D API.

Highlights:
• ⚡ Exact Target KB Compression: An automated binary-search engine calculates the exact quality and dimensions to hit your target file limit (e.g., <= 20 KB or 50 KB).
• 🛂 Passport & ID Photo Maker: Instant standard sizing (35x45mm, 2x2"), alignment guides, background fills, and ready-to-print 4x6" sheets.
• 🔄 Batch Format Converter: Convert up to 10 images across PNG, JPG, WebP, AVIF, BMP, and ICO with ZIP export.
• 📐 Pixel-Perfect Crop & Resize: Fixed aspect ratios (1:1, 16:9, 9:16) and custom pixel dimensions.
• 🎨 EyeDropper & Base64 Studio: Magnified pixel loupe, dominant palette extractor, and Data URI generator.
• 🔒 Absolute Privacy: Files are loaded into memory and manipulated locally. Zero bytes ever leave your device.

The project is completely free, runs with zero server latency on Cloudflare Pages, and the code is open source on GitHub: https://github.com/haideralifaiz...

I'd love to hear your feedback, thoughts on the UI, or any niche document specifications you'd like added!
