Hi Product Hunt! 👋 I'm the maker of DocHUB. As someone who frequently works with documents, I was constantly frustrated by the existing options. I had to either open slow, bloated, and expensive software just to do a simple task (like merging PDFs or OCR), or risk my privacy by uploading sensitive files to sketchy free online converters. I built DocHUB to solve my own itch. I wanted a lightweight, "Swiss Army knife" utility for Windows where everything runs purely locally on the machine. No cloud uploads, 100% privacy, and instant results. Here is what I packed into it: 📄 PDF Tools: Convert, split, local OCR, and a handy "1-click copy" for annotations. 🖼️ Image Tools: Local AI background removal, batch resizing, and screenshot manager. ✉️ Email Tools: Fast batch validation for email lists. To make it accessible, DocHUB currently supports 5 languages (English, Traditional/Simplified Chinese, Japanese, and Korean). I would love to hear your thoughts, feedback, or any feature requests you might have! I'll be hanging out in the comments all day to answer your questions. 🚀

@lidichu The local-first approach is a smart differentiator—there's real demand from users tired of privacy concerns with online tools. The multilingual support out of the gate shows you're thinking beyond the US market, which is where a lot of indie tools leave money on the table.
