24 alternatives to Free Image Converter and Optimizer

Hey HN, I built a small web tool to convert JPG, PNG, and WebP images into AVIF — no sign-up, no compression limits, no backend storage. It started as a weekend side project after I got frustrated with most AVIF converters being either too slow, paywalled, or without preview/download flexibility. Key features: - Drag & drop or multi-file upload - AVIF output with 100% quality (or configurable in backend) - Live image preview + original vs AVIF size savings - Individual or ZIP download - Built with Laravel, Tailwind, and vanilla JS - Images auto-delete after 2 hours No ads, no analytics.…

    Hey HN I built ImageConverter.dev because I got tired of “free” image converter sites that force uploads, or throttle conversions. So I made a tool that runs 100% client-side — meaning your images never leave your device. It’s built for speed, simplicity, and privacy. What it does Convert images between JPG, PNG, WebP Works offline once loaded (PWA support) How it works It uses the Canvas API and WebAssembly to handle conversions directly in the browser. There’s no upload, no tracking, no server costs, and it’s fast even on mid-range devices. Why I built it I wanted an instant, no-ads,…
