Hey Product Hunt community! 👋 I'm super excited to share MGToolbox with you today! 🚀 Like many of you, I constantly need quick utility tools: compressing images, merging PDFs, trimming audio clips, or extracting text from an image. But almost every online tool today forces you to upload your sensitive files to unknown cloud servers, wait in slow queues, or hit annoying daily paywalls. I built MGToolbox to fix this completely. It is a fast, 100% in-browser, privacy-first toolbox powered by WebAssembly and client-side AI. Your files NEVER leave your device — all processing happens directly in your browser. Here is what you can do with MGToolbox: 🖼️ Smart Image Tools: Compress to an exact target size (e.g., 100KB), resize, and convert formats (WebP, PNG, JPG) with zero loss. 📄 Private PDF Suite: Merge, split, rotate, and convert PDFs without server uploads or file size limits. 🎙️ On-Device AI & Audio: In-browser Speech-to-Text (Whisper), neural Text-to-Speech, noise removal, audio trimmer, and OCR text extraction. 🛠️ Developer Utilities: JSON formatters, JWT decoders, hash generators, and CSV converters with zero latency. 🌍 Multilingual: Available in 6 languages (English, Spanish, Portuguese, French, Japanese, Mongolian). ⚡ 100% Free & No Sign-up: No accounts, no paywalls, no tracking — just pure utility. I would love to hear your honest feedback, thoughts, or any tools you'd like to see added next. Thank you so much for checking it out! ❤️
