Hey Product Hunt! 👋 I'm the maker of ToolHive. I built this because I was tired of the same bad experience every time I needed to merge two PDFs or compress an image for an email: Watch my private file upload to some random server Hit a "you've used your 1 free file today, upgrade for $9/mo" paywall Get a watermarked output Wonder what that server actually did with my file Modern browsers can do 90% of what desktop software does. ToolHive is 140+ of the most common file, productivity, and AI tools — all running inside your browser. Your files never touch our server. No signup. No watermarks. No file-size limits. No daily caps. No hidden upgrade wall. A taste of what's inside: 📄 PDFs — merge, split, compress, rotate, protect, OCR, rearrange, sign 🖼️ Images — compress, resize, background removal (in-browser AI), HEIC→JPG, upscale, crop-to-circle, watermark, favicon generator 🎬 Videos — trim, merge, compress, MP4→MP3, flip, rotate, add subtitles, YouTube/TikTok/Instagram download 🎵 Audio — voice recorder, speed/pitch shift, vocal remover (karaoke), ringtone maker, equalizer 💻 Developer — JSON formatter, regex tester, JWT decoder, base64, hash generator, UUID, cron builder, markdown editor 🧮 Calculators — 15+ including scientific, BMR, GPA, mortgage, due date, fraction 🤖 AI text — summarizer, paraphraser, grammar checker, humanizer (Llama 3.1 via Groq) ⚙️ Generators — QR codes, invoices, resumes, passwords, citations (APA/MLA), email signatures 🌐 Available in 13 languages (English, Arabic, French, German, Spanish, Chinese, Japanese, Korean, Hindi, Portuguese, Russian, Ukrainian, Italian). The privacy claim is verifiable. Open DevTools → Network tab → compress an image. You'll see: zero outbound requests after the page loads. ffmpeg and the AI models are WebAssembly, running on your device.
