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.

@lidichu This is a clean and practical build. I’ve upvoted it because solving document work locally is something more people should take seriously, especially with privacy concerns growing. Well done on keeping it lightweight and focused.
