Hey Product Hunt! 👋 I’m the developer behind MediaDit. I built MediaDit because I was tired of "free" online media tools that act as data traps. They let you upload a file, process it on their cloud GPUs, and then demand a subscription before letting you download—while keeping a copy of your data. Mediadit is a fast, lightweight media utility toolkit. It runs 100% locally in your browser. What it does: -> Local AI Background Remover: Runs ONNX model weights directly in the browser via WebGL. No cloud API. -> Canvas Text Overlay: Create, customize, and drag multi-layered text with full font/style controls. -> Aspect-Locked Resize: Scale dimensions up or down (clamped at 4000px to prevent browser crashes). -> Real-Time Compression: Adjust JPEG/WebP quality sliders with live estimated file size and savings. -> Universal Exporter: Convert to PNG, WebP, or JPEG (features a solid white background fallback for alpha channels instead of default black). -> Multi-Language: Fully localized in English, Spanish, French, German, Portuguese, and Hindi. The Technical Approach: Built with Next.js and deployed on Vercel. All processing is strictly client-side. There is no backend server. When you drop a file into Mediadit, it never leaves your device. Because of this architecture: Absolute Privacy: No network requests with user data. Zero Friction: No accounts, no API rate limits. Truly Free: No watermarks, no paywalls. I’m a 21-year-old developer building this as a public utility. I’d love to hear your feedback on the WebGL processing speed, the UI, and what specific tools you’d want me to add next. Ask me anything about the architecture!
