    Hey HN! My friends and I built a new platform for generating images. The app is easy to use for people who find ComfyUI hard to use, or just simply don’t have a GPU to use it on. For those not familiar, ComfyUI is a great tool for using open-source models like Stable Diffusion. It’s primarily great because it’s a node-based tool, which means you can chain together models, upscalers, prompting nodes, etc… which let you create images in the exact aesthetic you want. There’s also a vibrant dev community behind ComfyUI, which means that there are a ton of nodes and customizability. We’re users…

    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,…

    Hi, Firstly, the link to the tool - https://github.com/DrRoach/DynamicImage I created a dynamic image sizing tool that allows images of any size to be generated on the fly. It's aims are as follows: a) Allow users of sites to upload images of any size without the site owner having to worry about their dimensions or having to resize them. b) Reduce load times for sites as images can be stored on their own dedicated server and be served in milliseconds. I'd love to hear some feedback as to what you think and whether you'd consider using this tool and if not, why not? All…
