Hey Product Hunt! 👋 I built Dumkera because I was frustrated by the state of online utility tools today. Need to merge two simple PDFs? You hit a paywall asking for $12/month. Need to format JSON or convert an image? Your file gets uploaded to a mysterious remote server with zero privacy guarantees. Dumkera takes a fundamentally different approach: 🔒 100% Client-Side Privacy: Tools run entirely in your web browser memory using WebAssembly and WebCrypto. Your files never touch external servers. ⚡ Zero Latency: Instant operations with zero upload waiting times. 🚫 Zero Signups & No Subscriptions: Completely open to use without creating accounts. 🛠️ 87 Handcrafted Tools: PDF suites, Developer formatters & encoders, Image optimizers, Financial calculators, and Cryptographic tools. We've just launched our production architecture and have 19 more tools queued on our roadmap. I’d love your feedback! What tool do you find yourself reaching for daily that we should add next?
