Hello HN! I want to share something me and a few friends have been working on for a while now — Zeroshot, a web tool that builds image classifiers using text-image models and autolabeling. What does this mean in practice? You can put together an image classifier in about 30 seconds that’s faster and more accurate than CLIP, but that you can deploy yourself however you’d like. It’s open source, commercially licensed, and doesn’t require you to pay anyone per API call. Here's a 2 minute video that shows it off: https://www.youtube.com/watch?v=S4R1gtmM-Lo How/why does it…

Hey HN I built ResizeImage.dev that runs 100% client-side — nothing gets uploaded, and it’s instant. What it does Resize, crop, and optimize images directly in your browser Supports JPG, PNG, WebP Works offline (PWA-ready) No tracking, no server, no data collection How it works It uses the Canvas API and WebAssembly codecs to process everything locally. All transformations happen in-memory, so no files ever leave your machine. Why I built it I needed a simple, no-BS way to resize images for web and social media — something fast, private.

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.…
