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! ❤️

Hey Product Hunt! 👋

Since our initial launch, we've expanded MGToolbox to 90+ 100% client-side tools while keeping our core promise: zero file uploads, zero accounts, and 100% local browser execution.

Today we're excited to launch our Multimedia & Audio DSP Studio expansion, powered entirely by hardware WebCodecs, Web Audio API, and ONNX WebGPU:

✨ What's New in MGToolbox:

1. 📱 Social Video Reframer (/en/social-video-reframer): Convert horizontal videos to 9:16 TikTok, Reels & YouTube Shorts with Gaussian blur background padding, smart crop, rotation, and speed controls — without downloading heavy 30MB+ FFmpeg WASM binaries.

2. 🎬 Quick Video Studio Upgrades (/en/quick-video-studio): Added hardware-accelerated scene transitions (Crossfade, Dip, Wipe, Slide, Zoom) and kinetic subtitle animations (Typewriter, Bounce, Pop, Slide Up).

3. 🎵 4-Stem Audio Separator (/en/ai-stem-separator): Split songs into Vocals, Drums, Bass, and Accompaniment right in your browser with an interactive solo/mute stem mixer.

4. 🎛️ Web Audio Creative Suite:

- Audio Reverb & Echo Studio (/en/audio-reverb-echo)

- Bass Booster & 10-Band ISO Equalizer (/en/bass-booster)

- Multi-Track Audio Joiner with Equal-Power Crossfade (/en/audio-joiner)

- Instant Sample-Accurate Reverse Audio (/en/reverse-audio)

🌍 Fully localized in 6 languages: English, Spanish, Portuguese, French, Japanese, and Mongolian.

Everything runs on your device's CPU/GPU, meaning your confidential PDFs, private voice recordings, and raw video footage never leave your computer.

We'd love for you to try out the new video & audio tools and let us know what utility we should build next! 🚀
