DH Tools

Hey everyone! 👋

I got tired of online tools (like PDF converters, image compressors, and OCR extractors) uploading my personal files to unknown servers, enforcing daily limits, or asking for credit cards.

So I spent the last few months building **DH Tools** — a lightweight, fast, and 100% client-side web utility portal.

### ⚡ What's included (45+ tools):

* **PDF & Office Suite:** PPTX to PDF, PDF to PNG/JPG, PDF Merger/Splitter, Excel to PDF, Markdown to PDF.

* **Image & AI OCR:** Image to Excel (extract tables from photo receipts), AI Background Remover, Bulk WebP/JPG Compressor, Carbon-style Code-to-Image exporter.

* **Developer & Network Tools:** JSON Formatter/Validator, JWT Decoder, Hash/UUID generators, IP/DNS Lookup, Waveform Audio/MP3 cutter.

### 🔒 Why it's different:

1. **Zero Server Storage:** Everything processes directly in your browser memory via WebAssembly, HTML5 Canvas, and WebCrypto APIs. Your files never leave your device.

2. **No Registration Required:** No forced sign-ups, no spam emails.

3. **PWA Enabled:** Works completely offline on desktop and mobile.

Here is a quick video demo showing the speed and offline workflow.

I'd love to hear your thoughts, feedback, or any new tools you'd like me to add next! 🚀
