Show HN: QuickImageResize.pro – Free Image Conversion and Resizing Tool

I built QuickImageResize.pro entirely on Replit as a comprehensive web-based image processing tool that handles virtually any image format you throw at it. The tool supports JPEG, PNG, GIF, WebP, BMP, HEIC, TIFF, AVIF, SVG, and even RAW formats (CR2, NEF, ARW, DNG) with automatic conversion capabilities.

Key features:

Drag-and-drop upload with real-time processing Smart format conversion (e.g., HEIC → JPEG, RAW → PNG)

Quality control and dimension resizing with aspect ratio preservation

AVIF support for 50% better compression than JPEG No file uploads to external servers - everything processed locally

Professional-grade Sharp library backend for high-quality results

Built with React/TypeScript frontend and Express.js backend using the Sharp image processing library, all developed and deployed on Replit. The tool automatically handles format detection and conversion, so you can upload a Canon RAW file and download it as a web-ready JPEG with custom dimensions.

Perfect for photographers, web developers, and anyone who needs reliable image processing without installing desktop software. Currently handling 10,000+ image transformations.

Replit made it incredibly easy to prototype, develop, and deploy this tool without any infrastructure setup - just pure focus on building features. The integrated environment handled everything from package management to production deployment.
