Hi HN, I built a WordPress plugin called Bandwidth Saver. It takes the images your site already has and serves them through Cloudflare R2 and Workers, which means zero egress fees and extremely low storage cost. The goal is to make image delivery fast and cheap without adding any of the complexity of traditional optimization plugins. The idea is simple. WordPress keeps generating images normally. The plugin rewrites the URLs on the frontend so images are served from a Cloudflare Worker. On the first request, the Worker fetches the original image and stores it in R2. After that, Cloudflare’s…

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,…

Hey HN! I built this because I was tired of manually creating OG images for every blog post and side project. How it works: - Send a POST request with JSON (title, subtitle, template, etc.) - Get back a PNG in ~50-100ms - No Puppeteer, no browser automation — uses node-canvas for fast server-side rendering Live demo on the homepage (no signup needed). Free tier includes 10 images/month. I'm launching on Product Hunt today too, but honestly HN feedback is what I care about most. Would love to hear: - What templates would be useful? - Any features missing? Happy to answer questions about…

Smallimg▲7Hi HN, I built a free image compression tool called Smallimg.cc that runs entirely in the browser. The main motivation was privacy. I was never comfortable uploading potentially sensitive images to a third-party server just for compression. This tool solves that by using JavaScript and WebAssembly to perform all the processing on the client-side. Your files are never transferred over the network. Key features: Total Privacy: Your images never leave your computer. Incredible Speed: No upload/download time, just instant processing. Full Control: You can adjust quality, resize, and convert…
