Hey Product Hunt community! 👋

I'm Dev Hridesh, the indie builder behind Useful Tools Zone. Super excited to finally share this with all of you today! 🚀

🤔 Why I built this:

Like many of you, I was constantly frustrated by legacy online file converters and media tools. Almost every tool today forces you to:

1. Upload your private personal videos, family photos, or confidential PDFs to unknown cloud servers.

2. Wait in artificial server queues or countdown timers.

3. Hit paywalls, sign-up traps, and watermark limitations for simple tasks.

I thought: Modern browsers and WebAssembly are powerful enough—why should our private files ever leave our local device?

💡 Introducing Useful Tools Zone:

A suite of 100% private, serverless client-side web utilities that run entirely inside your browser's local RAM:

🔒 100% Zero-Upload Privacy — Your files never touch a remote server. Everything is processed locally via WebAssembly and HTML5 Canvas.

✂️ Smart Video Splitter — Split long videos cleanly into 30s/60s clips for WhatsApp Status, Reels & Shorts with zero voice cuts.

✍️ Social Media Post Chunker — Convert long thoughts/WhatsApp posts into viral 9:16 PNG slides with high-CTR hooks.

📄 Merge Images & Compress PDF — Multi-document merging & compression directly in local memory.

⚡ Zero Server Latency — No queues, no countdowns, and seamless 1-click direct exports.

💸 100% Free Forever — No subscriptions, no credit cards, no forced logins.

🎯 What’s Next?

We are actively building more offline-first media utilities and creator tools.

I’d love to get your raw feedback, thoughts, or feature suggestions on what tools you'd like to see next. Thank you so much for your support! 🙏
